This course is aimed for using zod effectively in projects based on TypeScript (both browser and node.js). The benefits you gain with this course is not just simply coding, but also understanding when/why/how should you perform runtime validation.

zod is the missing piece to TypeScript's capabilities, which can guarantee type-safety only in compile-time.

zod can be used whenever the compiler cannot guarantee what happens in runtime. And... it's a very frequent usecase, such as HTTP calls, websockets, etc.

In this course you get quickly up and running by:

1. using zod with primitives and objects
2. adapting zod quickly to existing projects thanks to automatic generators
3. changing the strategy frm type-first to schema-first
4. using error-throwing parse or non-error-throwing safeParse basing on your needs
5. applying zod to the most common usecase - validating API responses
6. handling errors the most convenient way (out of many!)

Take advantage of runtime validation with zod. Take advantage of the detailed lessons in this course 🔥

How you build with Angular has changed quite a lot over the years.

For example, the inject function was introduced in version 14 but you might still be familiar with Angular's constructor injection.

Similarly, structural directives like ngif or ngfor have been replaced with @if and @for blocks since version 17 and beyond.

These are patterns that need to be adjusted if you want to stay up-to-date with the latest Angular has to provide.

Luckily, Angular gives you great tools in the form of a migration CLI for supporting your migration efforts as you incrementally update your App from older version features and patterns.

When you're done with this course you'll know how to target specific features, folders, and files to migrate to the latest Angular version.

You'll learn how to migrate:

• Structural directives with control flow syntax
• Constructor dependency inject to inject function
• Make components standalone
• Lazy load routes
• Input/Output decorators to signal-based API

Bootstrap is an incredibly popular CSS framework designed to make your website look great on mobile and desktop.

By the end of this course, you'll be familiar with many of the popular classes and components that Bootstrap uses to apply in your own projects.

For each feature you build in the course, you'll get a sense for what the relevant classes do for those components and links to documentation for further exploration.

For the course demo application, we will analyze the landing pages of Microsoft and Apple to identify common components that are implemented. When these are identified, you'll implement these components yourself with Bootstrap.

You'll build several common UI elements such as a nav bar, a carousel of images, Cards, and Forms.

Through building these components, you'll understand what is behind the different classes Bootstrap gives you and get familiar with how it exposes flex and grid layout for you.

This course is perfect for those looking for a lightweight alternative to NgRx Store that scales effortlessly.

Note: This course is being actively developed and more lessons will be added in the future.

Cursor is an AI-enhnaced code editor that allows you to call upon the robots to refactor or stub out functions for you with natural language.

• Backend Integration: You'll dive into back-end functionality, creating custom API endpoints, and interfacing with a database using Drizzle ORM to manage your content behind the scenes.
• Dynamic OG image generation: Every content website needs decent OG images for social sharing. You’ll learn how to dynamically generate the OG images for your pages and blog articles.

By the end of this course, you won't just have a theoretical understanding — you'll have a live, deployable full-stack blog that reflects current best practices in web development. You’ll also gain valuable and easily-transferrable skills for working with databases and containerizing and deploying full-stack web apps. This course is about building something tangible that you can use as a springboard for more complex projects down the line. So, let's learn how to build great content websites!

Controlling the network is the key to fast prototyping, bullet-proof tests, and efficient debugging. In this course, you will learn how to use Mock Service Worker for API mocking—from the setup and your first request handler to describing more complex network scenarios, such as dynamic requests, HTTP streams, and schema-first GraphQL mocking.

There are two major categories that you'll encounter when you start to build Full Stack applications.

You have: 💽 Database Management 👥 Authentication

Both of these contain their unique set of challenges and layer on top of each other as you build out your application.

You want to be able to Create, Read, Update, and Delete data from your database and also make sure that only the right users are performing these actions that you specify.

That is why this course is set up around these two categories.

You'll learn everything you need to about managing data using a service called Appwrite within your React application. Using Appwrite, you'll be able to create a database, upload files, and manage users.

You'll start out by building out the database while purposefully ignoring authentication/authorization through out the application.

The second part of the course will have you layer on auth so that you can enable users to log in and scope specific actions to roles that you'll create.

This course is focused on the full stack nature of web development so we will start with almost all of our UI built out for us. You can explore the course repository to get familiar with what components are available.

As new features are added to Nextjs app router that do not fall within the scope of the main course, these lessons will be updated and more will be added

How to use this course:

This course is meant to be a supplemental course for the Next Migrate Course.

The lessons match up as follows:

• The two 'primer' lessons follow the 'Initialize The App Router' lesson in the Next Migration Course.
• The 'migrating routes/pages' lessons (3 & 4) match up with the migrating routes lessons (sales, customer routes, and deposit route)
• The migrating route handler and api routes lessons follow the migration of customer api routes from the main course
• The refactoring of api routes to server components lessons follow "Refactor Customer Id Api Route Handler to Server Component" lesson
• The refactoring to server actions lessons follow/fall within the main course refactoring to server action lessons

This course will be updated as all the app router features and apis become stable

Credit for this application goes to Kent C. Dodds. The starter application was ported to Next.js from Kent's Remix workshops at Frontend Masters.

Why this course? Simply put, many are wondering how to migrate their application to Next.js new app router architecture and make use of server components, server actions, etc.

"Server components are the future." Twitter is saturated with comments like this. Many of us feel like it is tech version of Thanos, "Dread it. Run from it. Server Components arrive all the same."

Is this true? Emphatically no. So we can silence the infinity war now and say there is nothing wrong with using the pages router.

In fact, after the initial deployment lesson, you could stop this course and go make it something better or into something you want it to be using the pages router.

There are many incredible additions to Next.js new app router architecture. This is simply a course and resource for you should you choose/desire to migrate from pages router to app router.

You will learn how to:

• migrate api routes, pages, and nested layouts
• take advantage of routing in the app router for a better nested layout experience
• turn getServerSideProps into a React Server Component
• use server actions

And much more.

Due to the applications scale here are a few things to note:

• The course shows how to migrate a set of routes, api routes, etc with a few exceptions
• The remainder videos have been added to a supplemental course which you can find by searching for "Next Migration Course Extras" or clicking here. Consider them your bonus features and deleted scenes from the 'movie'.
• The extras course has been set up to align with the lessons here. For example:
  • As you create the app router, there are 'primer' videos for how to create a page and dynamic routes in the app router
  • As you go through migrating routes, you will find additional 'migrating routes' videos in the extras course
  • As you migrate api routes, the remainder of the api route migration videos are in the extras course

And with that you are good to go!

Start your journey today and experience the possibilities of the Next.js app router

• Subscribing to realtime database changes

This course is a deep dive into modern web development and I'm very excited to see what you're going to build on the other side! 🚀

Developers aren’t the only ones working on sites.

Marketers, copywriters, designers, and other non-coding roles all need to be able to make content changes. If you don't want to be bothered to open a PR every time a typo needs fixed, you need a CMS.

And Strapi is an amazing CMS option.

Strapi helps you quickly build a robust content API. You can host it yourself, it supports both RESTful and GraphQL, handles your authentication, lets you bring team members and it's highly customizable with plugins and extensions.

You can take those gains even further by adding Next.js 13 to the stack.

Next.js is fast, supports both server and client-side rendering, and features dynamic routes. Once you are generating dynamic pages from your CMS you’ll see just how powerful the combination of Strapi and Next.js is!

In this course you will do the following:

• Building Content Models with Strapi
• Fetching Data from your Headless CMS
• Using React Server Components
• Using the Next.js App directory
• Setting up pagination in Strapi and Next.js
• Parsing and rendering content in your Next.js application
• Connecting external services to your Headless CMS (like Cloudinary for Media Management)
• Deploying your Next.js and Strapi Applications to a production environment
• Setting up and using Strapi Plugins Transferring data between your Strapi environments

By the end of this course you’ll be building pages and managing your content like a pro!

SvelteKit is an application framework that builds on top of Svelte that provides you the app level functionality you need. It does the boring stuff that you don't want to so you can execute on the projects you want.

As you build with SvelteKit, you'll find it continues the philosphy of Svelte by adhering to Web Standards and APIs. It builds on top of Web APIs so when you're develop SvelteKit sites you are also learning skills that will transfer to any web-based project

In this course, you will build a modern SvelteKit blog powered by Sanity CMS. You'll start from scratch and build out a site that dynamically generates pages that you create inside Sanity.

As you build your blog, you will learn how to:

• Style Svelte components with TailwindCSS
• Add error pages to different routes
• Query your CMS in the front end
• Parse and validate your data with Zod and JSDoc
• Deploy both Sanity and your app to the web

Get started building web applications with Angular and Firebase.

In this course, you'll learn how to set up and use Firebase in your Angular applications using the AngularFire library.

We choose the AngularFire library because it is an official library created by the Firebase and Angular teams to work better with Angular.

It helps you by wrapping everything into observables and helps update zones.

By the end of this course, you'll be able to build web applications using Cloud Firestore as your database, Firebase Authentication as your Auth system, Cloud Storage to save files, and Firebase Hosting to deploy your applications to the web.

RTK Query is a powerful new way to model data fetching and caching in Redux applications. It’s built on top of Redux Toolkit, but hides almost any interaction with reducers, selectors or thunks behind custom hooks generated specifically for your API.

If your redux application relies heavily on data coming in from over the network, there’s a good chance RTK Query is worth adopting. It will allow you to remove significant chunks of code while also giving you new tools for error handling and cache invalidation that will make your users smile. Apply what I teach in this course and you won’t have to think about thunks ever again.

Sample code can be found here: https://github.com/xjamundx/egghead-rtkq

Learn how to build a pin-input component with state machines, Zag.js and React.

We’ll look at modeling a UI component with state machines, implementing those in a framework agnostic way using Zag.js, and connect the logic to the UI component.

This course is a must-watch if you’re unfamiliar with State machines, and want to learn how to use them to build UI components with ease.

In this course, you will:

• Learn fundamental concept of state machine, event and transition
• Model a UI component with state machine
• Connect state machine logic to UI
• Manage DOM events in state machines
• Create custom React hooks with state machines

Auth0 Actions are serverless developer tools you can use to customize Auth0.

Actions allow developers to extend Auth0 beyond what it can do out of the box by adding logic to login, user registration, password changes, and other events. You can quickly solve complex identity problems without hosting your own environment, and worrying about performance, maintenance, and security. Your code is stored and runs on infrastructure owned and maintained by Auth0.

Actions are JavaScript functions that run as part of a flow. Action integrations can be installed in the Dashboard, or Actions can be written directly in the Dashboard’s JavaScript code editor.

With the drag-and-drop flow editor, you can visually arrange Actions to build custom identity flows. You don’t have to rewrite your code to reorder and reconfigure functions.

Follow along with Will Johnson as you download a sample application configured with Auth0, then write code for several Actions.

Some examples of Actions you can create:

• Block access from certain counties with an Action from the Auth0 marketplace.
• Use an npm package and secrets to send a Slack message.
• Redirect users to an a URL after login and back to Auth0

This course will give you a solid foundation to start developing your own Actions.

Supabase is a collection of open-source tools that wrap around a PostgreSQL database. In this course, we look at building a realtime chat application with Remix, using Supabase for db hosting, authentication, authorization and subscribe to realtime db events - updating the UI as the database changes.

We will learn about:

• loaders and actions in Remix
• querying and mutating data with Supabase
• authentication with GitHub
• authorization with RLS
• merging client and server state with realtime events
• deploying a Remix app to Vercel

This course is 100% TypeScript, however, don't stress if you don't have any experience with TS, as Supabase does most of the heavy lifting here! 🎉

Almost every React application needs to fetch data from a server and cache the result between renders.

Traditionally, in-memory API Caching is something that has been done in React applications either on a per-component-level, which lead to application state running out of sync, or using a global state like Redux, which required a lot of hand-written code.

RTK Query is part of the official Redux Toolkit and provides an application-global API cache that abstracts most of that hand-written code away, leading to a lot more readable code bases.

It also offers a lot of advanced features like auto-generated hooks

In this course, you will learn about

• Using createApi to define multiple endpoints to interact with your API
• The auto generated useQuery hooks and how to use them in your application
• The RTK Query Dataflow and the role of the baseQuery function
• The Redux Devtools “RTK Query” Monitor and which actions are flowing though your app
• How to use RTK Query either with an ApiProvider or a pre-existing Redux store
• Using RTK Query with TypeScript

Personalizing the user experience is becoming more critical every day, even more so if your application or content is consumed by users in different parts of the world who most likely use other languages, date formats, currency, etc.

There are multiple solutions to make your content adapt to the location or language of your users. Still, many of these methods have become outdated, complex, or dependent on a particular framework.

Javascript also offers an internationalization solution, the Intl object.

Monorepos are an amazing way to collaborate on a multitude of projects with other team members. The ability to share code seamlessly between projects and have a single source of truth is paramount when working on projects with multiple moving wheels.

One of the tradeoffs of a Monorepo is all of the management you have to do to make your projects run flawlessly and simultaneously. Each project has it’s own linting, building, testing, and deploying that it runs whenever code in that project changes.

This becomes a real problem when each of your projects lints, builds, tests, and deploys on every PR into your monorepo. You might be fine with a handful of projects but as your applications scale and you accrue more projects, you will need a way to scale.

Turborepo is the tool that solves your monorepo’s needs.

Turborepo is a task runner for Monorepos. Turborepo caches the results of your CI tasks, schedules those tasks to run at maximum speed, and only runs tasks on the affected code in your PRs. And because of remote caching, your coworkers, wherever they are, will have the most up-to-date code possible.

One of the greatest things about it is that it's easy to use and can be incrementally adopted. Turborepo is a thin layer on top of your Monorepo.

Turborepo doesn't get in the way as it is only a task runner. You don't have to modify your application code or anything to make it work.

You’ll learn about

• How to set up caching for both local and remote
• CLI-commands and how they enhance your Monorepo
• Parallel execution of your tasks

So hop in and learn about Turborepo today!

Prerequisite: This course is a continuation of Introduction to Monorepos with NPM Workspaces. To get the most out of this course, watch Monorepos with NPM Workspaces first.

In a monorepo, all of your apps and packages reside in a single repo. Structuring your code this way has many organizational benefits. You can more easily manage your dependencies, and you can maintain more consistency across your various apps.

But, if you attempted to do this with just yarn or pnpm alone, you'll quickly start running into productivity issues. Your build times will be very long, and you'll have to make sure to run builds for any internal packages an app is depending on.

That's where Nx comes in.

Combining the speed of pnpm with the efficiency of Nx gives you an amazingly performant monorepo setup.

Nx builds a graph of your workspace and all of the connected dependencies. If there is a change anywhere, Nx will know about it and everything that is affected by it.

Which means that Nx is able to use caching to prevent unnecessary builds when nothing has changed. Nx's caching features enable blazing fast <10ms build times 🔥

You get to have all the advantages of the monorepo with none of the performance issues!

So start watching this course and learn how to achieve these speeds today.

The “Edge” is where you write and store your code where your data is being produced. This allows for a quick and efficient data transfer, eliminating or severely reducing lag.

Supabase is a suite of open-source tools wrapping a PostgreSQL database. It provides the building blocks of an app - database hosting, auth, file storage, real-time, and edge functions - so we can focus on what makes our app unique.

Cloudflare Workers are serverless functions that run at the Edge! In this course, we will use the Wrangler CLI tool for interfacing with your Cloudflare account and creating or publishing your Workers.

KV Storage is a cache that Cloudflare makes available to our Workers. It replicates across multiple CDN nodes, making it super performant to cache data.

Combined, these three things give you the benefits of that reduced lag in a smooth and streamlined process.

Throughout this course, Jon will teach you how to create a small blog that hits the key points of how to:

• Query Supabase from Cloudflare Workers
• Read and write KV Storage cache from Cloudflare Worker
• Cache Supabase response at the Edge with KV storage

And more!

Web3 is a paradigm shift in how applications are interacted with, ran, and built.

It’s not just a Pump-and-Dump scheme on cryptocurrencies or Bored Ape NFT profile pictures you can put on Twitter.

A fundamental tenet of Web3 is bringing ownership back to the user. You no longer have to trust that your data is being properly handled on someone else’s server (although, currently Web3 ecosystem mainly depends on centralized infrastructure such as GitHub).

This ownership is achieved through blockchain, cryptocurrencies, NFTs, and smart contracts.

A great example of this type of ownership is through how you exchange money in Web3. There is no intermediary like Stripe, or PayPal to process your transactions. You can even build your own smart contracts that receive crypto (e.g. Ethereum or ‘eth’ for short) and then process that eth how you’d like.

Building this type of smart contract is exactly what Matías is going to show you how to do right now.

Matías builds out a Web3 application that allows you to receive tips in the form of eth in a tip jar on your website. This means your application will be backed by a smart contract that’s accepts eth, stores data, and emits Solidity events.

The frontend application uses SvelteKit which you’ll see how easy it is to get up and be productive with in minutes. A huge benefit here is that the JavaScript you write is just that, JavaScript. You’ll be able to take what you learn and implement it into any framework of your choosing.

While you build this application you will learn how to:

• Write a smart contract using Solidity language
• Test the smart contract using just JavaScript through the waffle framework
• Communicate and interact with the smart contract using ethers.js in a SvelteKit application
• Deploy your smart contract to make it public and accessible to anyone

Smart Contracts are programs stored on the blockchain that run when certain conditions are fulfilled.

These Smart Contracts have many benefits to them such as speed, transparency, and security. The contract is immediately run as soon as the requirements are fulfilled. This creates a system where you place trust in a transparent system, instead of an opaque intermediary.

Noah will show you how to write, test, and deploy smart contracts on Ethereum, using the popular smart contract language, Solidity. You'll also learn how to use Foundry, a popular dev-toolbelt, to streamline our whole development process.

Throughout this course, you'll learn how to:

• safely and securely set up Smart Contracts
• write and read data on your Smart Contract
• send transactions with specific arguments to your Smart Contract
• deploy your Smart Contract using Forge and QuickNode

And more!

Approaching testing at a component level has definitely its benefits. Seeing your component rendered in isolation, and making sure it behaves correctly with different properties is definitely faster that trying to interact with an app at end-to-end level. On the other hand, seeing your app render in a browser in an end-to-end test is a significant advantage.

With Cypress’ component testing you can now take the best of both worlds. Render component and interact with it in a real browser. You can pass different properties, spy on its function calls, click and type into them or even intercept its network calls. All this with a minimal setup and vast options.

What you'll learn

• setup component testing in Cypress
• customize component mounting properties
• render a component in a browser
• examine a component with different passed properties
• make asserrtions on component’s emitted events
• render a component with content passed into its <slot />
• catch edge cases by calling actions and passing values into Pinia’s state
• handle router and it’s effect component behavior

Next.js is one of the most popular server-side-rendered React frameworks you can use to build production-ready serverless applications in record time.

On the other hand, Fauna is a flexible, serverless, distributed document-relational database. Fauna has a powerful GraphQL API and custom resolver support.

Using Next.js and Fauna, you can build robust, feature-rich, production-ready full-stack applications without the hassle of managing any servers or databases.

In this course, Shadid guides you through building your very own full-stack serverless marketplace application using Next.js, GraphQL, and Fauna.

You will learn,

• How to work with Apollo GraphQL Client in Next.js
• How to setup Fauna GraphQL
• Data modeling in Fauna
• How to write custom Fauna GraphQL Resolvers (UDFs)
• How to authenticate with Auth0?
• Stripe payment

D3, or Data Driven Documents, is the defacto standard for data visualization on the web. It's an incredibly powerful library that gives you all the tools you need to build just about visualization you can dream of.

D3 is not a collection of predefined charts. Instead, it's a robust set of utilities you can use to ingest and transform data, to map that data to screen values, and ultimately to manipulate the DOM to render your visuals.

When working with React, D3's desire to manipulate the DOM is at odds with React's goal of rendering the UI as a function of state. So how do we handle this? Simply put, we use D3 for everything up to the point where we want to render our output, and then we hand all that data to React for rendering.

In this course, we'll start from scratch and build out an SVG bar chart for some sample data. We'll lean on D3 for its tools and then hand that data off to React for rendering.

In this course, Colby is going to do a deep dive into creating a full store for your products. You'll learn how to set up and use GraphCMS as your content management system. You'll learn about the Cloudinary UI extension and how to use it to host your images. You'll learn about Snipcart and using the useSnipcart hook to handle the cart state and the checkout. You'll learn how to implement Stripe as your payment gateway. And lastly, you'll learn how to deploy a Next js app to vercel from github with environment variables.

In this course we demonstrate how to get started with Microsoft Playwright. We follow this up with various features of Playwright that make it extremely easy for you to test and automate modern web applications.

Jotai's state management is primitive and flexible. This gives you room to build, compose, and share state throughout your application exactly how you need it.

This flexibility can become hard to manage when you have complex requirements that span across a number of states your application can be in.

Jotai lets you leverage other state management solutions through integrations so that you can solve the problem you're facing exactly how you need to.

One of those integrations is XState. XState gives you a safe abstraction to enumerate and handle the complex states your application can be in.

With Jotai + XState, you get the flexibility and ease of use of Jotai with the power of XState.

XState is a sophisticated library to provide a better and safer abstraction for state management.

Intro

TypeScript has been growing in popularity among companies who build their products with React, and for good reason!

Types play nicely when working with components, and lead to a super smooth developer experience.

But what if your application is already being shipped and continuously deployed? It doesn't mean you can't take advantage of everything TypeScript has to offer.

Refactoring an application to TypeScript doesn't have to be daunting. Follow Chance's lead, and you'll be well on your way!

The course starts with an overview of some of Chance's favorite tools and their TypeScript-specific settings. These tools will help you search your project's TypeScript paths for auto-importing, a shorthand tool for writing JSX and TypeScript to speed up your writing, and a tool for helping you to maintain your code to a high quality.

The tools are Emmet, ESLint, Prettier, and a variety of VSCode extensions. There's even some rollup and Babel thrown in for transpiling and compiling our TypeScript to make configuration and build setup a breeze.

The Project

Once the tooling is in place, Chance works through converting a completely functional Windows 98-style Minesweeper game away from JS React into one that takes advantage of the power of TypeScript. It'll be clear how changing the JS to TS will not affect the functionality of the game at all but improves the safety of your app.

Topics in the second half of the course include component refactoring as well as adding types to React Hooks, useReducer, and Context. You'll even see how to add types to a legacy Class component!

Chance has several years of experience working with component libraries and this is your opportunity to learn from his experience and apply his process to your own.

Gain these Skills

Chance will give you the knowledge of how to incorporate TypeScript into any React application, whether it's shipped and continuously deployed or not. You'll take the practices and tools that you learn here to be much more productive in your TypeScript, wherever you use it. Lastly, He will give you the knowledge of when you see React Types vs your own custom types.

Prerequisites

This is not an introduction to React or TypeScript course. You will need to have a basic understanding of the two to be able to follow along. If you don't have that basic understanding, or just want a refresher on the subjects, The Beginner's Guide to React and Up and Running with TypeScript are the best two places to start.

What's Next?

The Beginner's Guide to React is the best place to go if you are just starting out in React. This course by Kent C. Dodds covers all the basics to get you up and running with React.

Advanced TypeScript Fundamentals by Marius Schulz will take you beyond the basics to teach you some new language features TypeScript has to offer courtesy of the wonderful team over ta TypeScript.

TypeScript: Tips and Tricks by Kamran Ahmed is where to go once you've started using TypeScript but looking for that little something to take it to the next level.

Most developers would raise an eyebrow if they saw database queries being done in a for-loop, but GraphQL provides just enough abstraction that it isn't always intuitive exactly how many times each resolver fires at scale, nor is it obvious how to batch operations efficiently and still return the correct results to the correct consumer.

You'll learn how to use the GraphQL Data Loader pattern to improve the performance of your application, and solve scaling issues before they become a problem.

To do this, we'll first implement our own naive version of the pattern to understand why the API is shaped how it is. Then we will switch over to the official DataLoader package and explore the benefits further.

Skills you'll Gain

• Implement a cache layer to optimize your requests
• Batch requests so your Database isn't overloaded
• Build a performant GraphQL API

Front-end web architecture has made exciting advances in recent years. But before we get to that we need to have a discussion on what has led us to this point and the driving principles behind it.

Since JQuery, we've progressively been decoupling our logic from the DOM. After JQuery, frameworks like Angular were able to abstract that logic into controllers and services. Then Redux came along and brought a simplified that let us reorganize our logic into more cohesive units.

We should be taking advantage of improved decoupling in the modern web. If you can write a function you can write an endpoint. And if you understand frontend architecture principles, then you already understand cloud architecture principles.

In this course, you will learn how to decouple JavaScript functions from the environment they live in. By using the Serverless framework and AWS, you will see how straightforward it is to create an endpoint.

So check out this course and start lifting your functions into the cloud today!

Scripting can save you a ton of time by automating your daily workflows.

But it's hard to justify the time investment of learning Bash to write your scripts.

Bash is the great barrier we all face when trying to script away our daily tasks. There are some common problems that we run into when dealing with it. Like what if we want to display images? Or share our script with other devs cross platform?

You know what you want your script to do. You know you could figure it out if you had the time. But it's all just too darn much.

What if you could write your scripts in JavaScript, launch a GUI, and were actually easy to share with your team? audible gasp

Script Kit is the tool that’s been missing from your developer toolbox for so, so long. 🛠

Download the new hotness here: https://scriptkit.com 🔥

We even use Script Kit internally at egghead.io to manage our lesson transcripts! With a single script, we query an API to list the transcripts, modify them as necessary, then post the changes.

This course was made to show you what Script Kit can do for you.

John Lindquist, the creator of Script Kit and co-founder of egghead.io, has put together this series of lessons to give a quick overview of the features of Script Kit to help you get oriented.

We know you’ll be off and having a blast with your own scripting ideas in no time!

Intro

Animations do more than just look good. They can draw the user's attention to important information or let them know they can interact with certain elements.

You can use them to smooth transitions and bring your applications to life. It makes you stand out from the usual wall of text that you see on most applications.

But here is the issue, animations can get complicated. You have to have a good understanding of how CSS works but it takes hours of studying before you can even start trying to animate.

Framer Motion solves this for you and Will Johnson will show you how.

The Project

In this course, you’ll iteratively add animation to a fully-styled shopping list app that’s built-in React.

You’ll see how Framer works out of the box, and learn just how customizable it is. Throughout the course, Will demonstrates animation through changing size, direction, and even appearance.

It has smart defaults that handle making the animations smooth and performant. Automatically animating layout changes. It does so much for you it almost feels like you're cheating.

You’ll even see how to animate the path of an SVG making it draw the path for your image.

Gain these Skills

Will gives you the knowledge of how to incorporate Framer Motion into any React application. You will be able to customize your animations to do whatever it is you want/need and show your users what items on your app are interactable. You’ll be able to take your static application and make it interactive.

Prerequisites

There are no prerequisites for this course. The application we are working on is already built for you so you just have to be able to follow along with Will as he integrates Framer Motion into the app.

What’s Next?

If you are further interested in learning about animating your applications, Spring Animation in React with React Spring is a great place to learn! Christian Nwamba will teach you the skills to begin using the react-spring library and add animation to your React components.

If you are interested in more courses by Will Johnson, he has a mini-course on how to Create A Blog With Jekyll. Will shows you how to download, install Jekyll plugins, and create blog posts.

Build a fully managed, serverless GraphQL API powered by TypeScript and AWS CDK in a matter of hours, not days.

AWS CDK gives us the power to go all-in with infrastructure as code for AWS. With it, we can create a full GraphQL API with AppSync, a database with DynamoDB, serverless functions with Lambda, and much more.

In this course, you will learn how to do all of the above from your command line and code editor, which will save you time and give you greater flexibility.

Want to delete your stack? That's fine, just run cdk destroy and poof, all of the resources are gone. Changed your mind? Just deploy the stack again and they all come back.

AWS CDK makes it that easy.

And since we are working from the command line and our code editor, we will take advantage of TypeScript and other third-party libraries to improve our developer experience.

So stop wasting time in the AWS console, check out this course, and learn how to leverage infrastructure as code to your advantage.

GROQ (Graph-Relational Object Queries) is a query language for JSON. This course will help you build your first query and walk you through filters, projections, functions, and the other features of GROQ to help you request exactly the data that you want.

In this course, John Lindquist will teach you how to create and structure GROQ queries to load exactly the data you want.

The course will kick off by giving you a quick introduction on what GROQ is, and then you will learn how to use the different features the language supports.

At the end of this course you will know how to use GROQ in the context of a Sanity.io dataset.

Your app can react in various way on different network conditions. Cypress has a great toolset for setting up those conditions, which enable you to test your app thoroughly. That way you can ship your app with confidence.

Cypress’ .intercept() command is one of the most fun command to use. And it’s also one of the most useful.

Especially when you are done with all your happy paths and want to increase your test coverage with some edge cases.

These edge cases can mean different data, headers or server behavior. You can modify all of these, dynamically or with a static fixture prepared beforehand

In this course, we will be building a React Native news app that is read-only when offline.

The videos are recorded on a Mac with an iPhone 13 Simulator using plain React Native, but you can do this course using Android, Windows and even the Expo managed workflow. See the lesson description for platform-specific instructions. The solutions repo has been verified to work on a Pixel 3a Emulator on Mac.

The completed app for this course is available here and each lesson will include a link to the commit that added the code so you can check your work.

After we build our news app, we're going to enhance it to make it read-only when offline using urql'g GraphCache.

This course will require you to run the api locally on your device. The api repo is available here.

Resources:

• urql: https://formidable.com/open-source/urql/docs/

Get started building dynamic apps with GraphQL and Vue3.

As your app scales, so does the complexity of managing your routes and API endpoints.

It gets tiresome.

But this aspect of web development can be streamlined considerably!

GraphQL is a powerful tool for querying and mutating your data. In this course, we are going to create a Vue3 app that leverages GraphQL to create a dynamic front end.

But what does GraphQL do?

Its power comes from giving you a single endpoint that you make all your queries to. Instead of making a request to a specific endpoint and getting a fixed response, you can write flexible queries to a single endpoint.

Vue3 has some great new features that we will be exploring, such as the setup script syntax. But you won't just be exploring Vue3's new features, we will be building a dynamic front end with an index, view pages generated from data, and forms.

To make our frontend dynamic, we will be powering it with GraphQL. We start with the basics by creating queries but we move on to more advanced topics such as query params, mutations, and pagination.

To actually use GraphQL in our Vue app we will be using the Vue Apollo Client. Which gives us convenient methods for making queries, getting the data back into the client, and handling errors.

Gain These Skills

• Add GraphQL to a Vue 3 project
• Query and mutate data with GraphQL in Vue 3
• Create data-driven views with Apollo client
• Handle routing within a Vue 3 project
• Implement optimistic updates and infinite scroll

Prerequisites

Some entry-level knowledge on Vue and GraphQL is recommended, but this course is beginner-friendly enough to where it isn't a strict requirement.

If you want to build a deeper foundation for both Vue and GraphQL we have a couple of awesome courses that you can hack through.

For Vue, check out The Beginner's Guide to Vue 3, which is also by Kevin. It's great for both newcomers to web dev and veterans alike.

And for GraphQL, work through GraphQL Query Language from Eve Porcello. Eve literally wrote the book on learning GraphQL and her course is similarly top quality.

What's Next?

Progressive Web Apps are a more advanced topic, and converting an existing Single Page Vue App into one makes for an excellent follow-up project. -> Offline-First Progressive Web Apps (PWA) in Vue.js

If you want to take your GraphQL game to the next level, then becoming an expert in designing GraphQL schemas is the way to go. -> Designing GraphQL Schemas

And I know the following recommendation is a React course but it really is that good. You will learn some advanced techniques that will be applicable to Vue or any other Apollo compatible framework that you work with. -> Manage State in React Apps with Apollo Client and GraphQL

todo

Storybook is a tool for UI development. It makes development faster and easier by isolating components. This allows you to work on one component at a time. You can develop entire UIs without needing to start up a complex dev stack, force specific data into your database.

In this course, Michael Chan will teach you how to integrate Storybook 6.3 with Next.js 11 so that you can flawlessly build UIs.

The course will kick off by taking the default Next.js page and turning it into a Story. You will then learn how to leverage Story Args, configure the next/image component to be unoptimized, and mock server workers with MSW inside Storybook.

You're going to find cloud services being used at nearly any enterprise you work for. So it's important for us developers to at least have a high-level understanding of this infrastructure.

And since AWS has the dominant share of the cloud market, being familiar with it is incredibly valuable and opens a lot of doors.

But gaining that familiarity isn't easy. Just browsing through the list of 200+ services is overwhelming.

Getting started with learning AWS usually involves having a dozen or more open tabs and the feeling that you're going down a rabbit hole that never ends.

This course is an alternative to that stress. It has been structured like a boat tour on a river of knowledge, linearly guiding you through the core of AWS.

By the end of this course, you will be confidently spinning up servers, creating relational databases, storing static assets, and writing serverless functions with confidence.

So, whether you need to learn AWS for your current job or are looking to earn your cloud practitioner certification, start watching this course and gain the skills you need today.

The Edge is one of the most exciting new topics in web development. At the front of the pack is Cloudflare, whose network boasts servers located in hundreds of cities all over the world instead of in regions like "East" or "West".

More servers in more locations mean a faster experience for your users.

But what about the data part of the equation?

If the application you're working on skews more toward "reading" rather than "writing" data, Cloudflare Workers KV is a perfect fit.

Once you create a KV namespace— the "KV" stands for "key-value"— Cloudflare keeps track of your application data. The most commonly accessed data will be propagated around the world to the various Edge servers, while less popular data will be stored in more central locations.

Kristian Freeman has produced courses that introduce how to build and deploy sites and JSON APIs powered by Cloudflare Workers.

Today, he will show you how Workers KV can be integrated into a Cloudflare Workers project through building a Todo App.

The Project

Before you groan about a bland Todo App, think about it this way:

The Todo App is the perfect example of the CRUD operations. Cloudflare KV has its own nuances for reading and writing data through a concept called Binding that is easier to grok when you understand the larger example as a whole.

As the course progresses, Kristian shares examples of how you can store more complex key-values, along with data operations like editing and filtering.

One of the coolest features that Cloudflare KV allows for is user-specific data that is tied to the IP address the request originates from. In other words, you'll be able to share your deployed Todo app with anyone around the world, and they will only see their personal items.

Gain these Skills

• Manipulating data using Cloudflare Workers KV
• Make data unique to each user without logging in
• Effectively store lightweight data in Cloudflare Workers KV
• Setting up a key-value store and connected projects
• Reading and writing to a serverless key-value store
• Storing complex values in a Cloudflare KV store

Prerequisites

You'll need to have a basic understanding of what Cloudflare Workers is recommended but not necessary. This course is relatively beginner-friendly into the world of Workers KV that you can get by with no knowledge on Cloudflare Workers.

But if you want to get the most out of this course, we would recommend taking Introduction to Cloudflare Workers to get a better understanding of how Workers KV comes into play.

Protect yourself from unexpected charges by learning how to use Firebase emulators.

By using Firebase emulators you no longer have to create a second dev firebase project to avoid using production data. You also don't run the risk of having a cloud function crash and run up a huge bill.

In this course, you'll learn how to set up and use Firebase's authentication, function, and Firestore emulators. You will also learn how to safely set up Cloud Function emulation, import seed data into your emulators, and disable the emulators in production.

By the end of this course, you'll be able to confidently set up a safe environment for testing in your own applications!

Create a serverless application and deploy it in under thirty minutes!

We'll be using Netlify, Vite, TypeScript, and React in our project. This stack synergizes extremely well for rapidly developing professional-quality applications.

If you haven't heard of Vite, it's the French word for quick! It's also a build tool that consists of a dev-server and an extremely fast bundler. It makes for a rapid development loop.

As for the rest. Netlify makes hosting fast and easy with serverless functions and continuous deployment. React enables you to quickly create reusable components. And TypeScript helps you write cleaner code that is easier to refactor.

So get started and learn how to use this stack in your own applications!

For your frontend, this application will be using Next.js and Tailwind CSS. You will learn how to maneuver around an app and build a strong static pricing page.

For your backend AND authentication, we will make use of Supabase. Supabase is open source and is all of the backend services that you will need to build your site. It includes a dedicated and scalable Postgres database and user management with Row Level Security!

Lastly, for payments, you will be using Stripe. It will be an individual payment checkout system that will create and update users' subscriptions.

Jon will take you through all of this and more in just 1 hour and 10 minutes!

Optimizing your application is key to being able to provide your users with a clean and pleasurable experience.

To make your app as performant as possible, you have to send to the browser the least amount of code possible. Also, you want to render the least amount of components on a page at a time as necessary. Then you also want to rerender components in the least amount of time possible.

Tyler has found that working in enterprises and startup cultures that, as you get more developers in a team and as your application grows, a lot of these little practices become ignored or forgotten or missed on a refactor or a pull request. They start to build up over time. Then, at the end of the day, you have a slow-performing app. You go through it, and you have to do all these little updates.

In each one of these lessons, Tyler going to be adding and deleting code to walk you through how to optimize a React app using a dashboard React app as the example.

(todo)

Web accessibility (also referred to as a11y) is the design and creation of websites that can be used by everyone. Accessibility support is necessary to allow assistive technology to interpret web pages.

React fully supports building accessible websites, often by using standard HTML techniques.

Erin Doyle is an expert in creating accessible React applications and has developed a course that will give you a concrete process for auditing react apps for accessibility. In this course, you will go through different tools and libraries to audit components in a React app.

Notion is a note taking application that empowers super productive workflows, without compromising on beautiful UI or intuitive UX. Next.js is a React framework that sprinkles in server-side logic in the places it is needed. This allows each page to be dynamically rendered by the client, rendered by the server or entirely static and rendered at build-time. This makes it an incredibly flexible option that can start off as simple as create-react-app and incrementally introduce complexity as the application evolves.

In this course, you will learn how to pre-render static pages with data from the Notion API. We will cover querying page, block and database data, as well as updating properties with mutations, and some helpful techniques for transforming raw responses into convenient data structures for our React components. Using Incremental Static Regeneration (ISR), we will learn about dynamically creating static pages any time new data is available in Notion.

We will be building two example applications - a recipe app and a movie picker. The data for these applications will live in Notion, and be queried by Next.js at build time. This allows us to use Notion for its delightful authoring experience, and Next.js to make this data publicly available via super performant static pages.

Zustand is a state management library aimed at staying simple and un-opinionated so that you as the developer can build your application as you see fit. To do this it creates a store (module of state) that you can subscribe components to read and update data from.

Zustand leans on hooks as the primary way to interact with your state. This means you get less boilerplate and a centralized, action-based state management solution that scales with the complexity of your app.

Daishi, a core contributor of Zustand, will show you the inner workings of the library by creating a small version of it. You learn how Zustand's API came to be and gain a better understanding of it by the end of this course.

At the core of a good client-side GraphQL library is a cache. The cache is very important for improving the efficiency of your data retrieval and providing your users with a clean user experience.

In this course, we're going to see how Apollo's powerful cache helps easily solve complex UI problems, such as pagination, handling loading and error states, optimistic updates, and minimizing network requests.

We'll start from the basics, and look at how to make queries and mutations, but then we'll look at how the cache is behind most of Apollo's immediate benefits. We'll explore in-depth how it works, how it stores data, and how we can manually modify it manually for advanced scenarios.

Even if your backend doesn't fully support GraphQL yet, we'll look at how to write GraphQL queries in your components that retrieve local client state under the hood - or that can even make REST API calls.

After completing this course, you will be able to build well-designed user interfaces without spending a lot of time (if even) styling every component and element. You will drastically simplify your front-end work and learn to modify and build on top of existing design systems.

Chakra UI is a React components library with built-in accessibility. It comes with a modern-looking design system that's easily extendable and configurable. The simple styling API significantly reduces development time, so developers can quickly prototype their ideas and achieve the desired style and "brand" by editing a single file.

The result of using Chakra UI is a well-designed app that's accessible out-of-the-box, achieved with minimal effort and time.

In this course, you'll learn how to build a checkout UI.

In the first phase of the course, you will learn all about the built-in components. Then we will override the theme, add custom fonts and colors, and make our UI unique.

This course provides all the design files to follow along. You can download them here.

A skeleton loader is a popular UI pattern for loading screens: instead of a spinner, we show static or an animated placeholder for the information that is still loading.

In this course, we go through 3 instrumental libraries for React Native - Linear Gradient, Masked View, and Reanimated 2 - and in the end, we use them in tandem to build a Skeleton Loader.

Linear Gradient Expo | Pure React Native

Masked View Expo | Pure React Native

Reanimated 2 Expo | Pure React Native

This course is built using an iOS simulator on plain React Native. Still, it will work on Expo and Android (you'll need to follow the relevant installation instructions available in the documentation).

The finished code for the skeleton loader (last 2 lessons) is available on Expo Snack.

Tailwind CSS is a utility-first CSS framework for rapidly building custom user interfaces. It is a highly customizable, low-level CSS framework that gives you all of the building blocks you need to build bespoke designs.

Prisma is an open-source ORM. It consists of the following parts:

• Prisma Client: Auto-generated and type-safe query builder
• Prisma Migrate: Migration system
• Prisma Studio: GUI to view and edit data in your database

Prisma Client can be used in any Node.js or TypeScript backend application (including serverless applications and microservices). This can be a REST API, a GraphQL API, a gRPC API, or anything else that needs a database.

In this course, you will learn how to initialize Prisma in a TypeScript Node project, use Prisma Client to create and find records, use Express to create data dynamically, and more!

Best practices for building & testing redux applications have changed dramatically over time. This course aims to be a comprehensive and up-to-date resource for those seeking to confidently test their redux apps. Whether you're just getting started or want to improve on your existing testing strategy, there will be something in this course for you.

This first few lessons of this course look at how to add jest to an existing react/redux application that was built on top of vite. We cover basic functionality like using npm test vs npx jest and generating and using code coverage to inform our testing strategy.

The next 10 or so lessons cover the specifics of unit testing the redux code in our application. We'll go over how to test reducers, selectors and thunks. As part of this we'll touch on mocking APIs and using Redux Mock Store as well as running actions through our applications' actual reducers to broaden our test coverage.

In the final part of this course we'll look at how we can test our redux connected react components using the various utilities that come with the React Testing Library. We'll cover simulating various kinds of user input with the User Event Module, populating our redux store with test data, using jest spies, how to wait for asynchronous tasks to complete, and several approaches for finding & asserting that visual elements exist on the page.

This course is built on top of content that was created for the Modern Redux with RTK and TypeScript course and I highly recommend you start there if you haven't completed it already. It does expect a basic familiarity with react, redux and jest. TypeScript is used in these lessons, but is not a major focus and hopefully won't distract you too much if you prefer plain JavaScript.

No matter your experience level with redux and testing react applications, I'm confident your abilities will level up as you watch this course and follow along with the examples.

Thank you!

In this course we take a basic shopping cart application built with React and fully power it with Redux and RTK using TypeScript. For those of you familiar with Redux Hooks, we use those here, but the emphasis is more on how the Redux Toolkit simplifies the process of setting up your redux application including building slices, reducers, selectors and thunks. Everything we do in the course is typed with TypeScript to make your application development process as smooth and powerful as possible.

jotai is a primitive and flexible state management solution for React.

jotai gives you a minimalistic API that you can use that separates your state management from your UI. You get the benefits of well manages state AND you don't have to set up any boilerplate like defining actions, reducers, dispatchers, or stores.

You create an atom and you're off to the races managing your application state.

In this course, you'll build an SVG drawing application. You'll see how you can represent the canvas as state through atoms and add svg path, change the path colors, delete, and even undo actions. You'll sum up your learning by learning how jotai can isolate state in your applications by using and composing Providers.

You'll be able to use the concepts you learn here to manage any state in your own application.

Learn how to make flexible customized Twitch Scenes using the static site generator Eleventy (11ty), CSS, and ComfyJS.

Throughout this course, you'll create scenes for preshow, host, and main desktop display streaming purposes. Using ComfyJS, we'll add embedded chat and be able to create responses to chat commands. Finally, we'll see how to actually setup the scenes in OBS to prepare to use them for your stream.

Bonus: you'll learn a bit more about CSS grid layout, and also the "cicada principle" to be able to show the commands randomly across the scene!

Every developer who has attempted to demystify OAuth 2.0 must be presented with mind-bugging complicated flow diagrams. It becomes worse when you try to understand all the terminologies of OAuth 2.0 and Open ID protocols.

There is no getting around the OAuth 2.0 flow being complicated with back and forth between your browser, the service you are authenticating with, and the application you want to access.

This course gets straight to the point without any application code distracting you from the core takeaway -- You will learn how to authenticate and authorize yourself using GitHub as your Auth Server.

We'll first cover the OAuth 2.0 flow for authentication and then integrate the Open ID protocol for authorization.

LIVE EVENT: Register here for a live webinar with Christian on OAuth. Bring any questions you have from taking this course!

Vue is a progressive framework for building UIs that allows you to incrementally integrate the technology into any existing project that you're working on. This makes it a great tool for you to learn as you can bring it anywhere.

This course is for learners just starting out in web development as well as for those who want to get up to speed on Vue 3 as fast as possible. You'll learn all the foundational skills of web development and how they are presented in Vue.

We will start with an HTML, CSS, and JavaScript file as to not distract you with any possible tooling that goes on top of the building websites with Vue.

You will incrementally build an app that sells comedy event tickets. In the end, you'll see how to deploy the application with Netlify Drag and Drop.

Cloudflare Workers let you write JavaScript Service Workers that run directly in Cloudflare's 200+ edge locations around the world.

With a Cloudflare Worker, you can modify your site's HTTP requests and responses, make parallel requests, and even reply directly from the edge.

Cloudflare Workers are written against a similar API to the W3C Service Workers standard. However, while Service Workers run inside the end user's browser, Cloudflare Workers run on Cloudflare's servers. This means that Cloudflare Workers can implement trusted code (which the client cannot tamper with), and will work no matter what browser the user is running.

In this course, Kristian Freeman will teach you how to build and deploy a Serverless API with Cloudflare Workers. By learning how to build your own serverless JSON APIs, you can effectively manage a highly-available backend for your projects, without needing to learn DevOps or manage services.

Listening to and responding to events is a foundational skill for building software for the web. The Document Object Model, or DOM for short, has a powerful built-in event system. And yet, many of us have a pretty basic understanding of the DOM event system and only scratch the surface of the available power.

This lack of understanding leads to bugs in our applications and writing lots of code to work around the DOM event system rather than leveraging it. The goal of the course is that you will walk away with the confidence to successfully and meaningfully engage with the DOM event system.

The DOM event visualizer domevents.dev will be used to explain many behaviors throughout the course. You are welcome to play with the visualizer yourself to continue your learning

One of the hardest parts of learning AWS is understanding how the different moving parts work together.

In this course, we tackle a real-world project of deploying the blogging platform Ghost to AWS using EC2 (the server where Ghost will run) and RDS (a relational database for Ghost to store data).

This course ties together skills like networking, SSH, and using the command line while getting a realistic full-stack platform up and running.

Whether you're studying for a certificate like Certified Cloud Practitioner or just learning for fun, this hands-on project will be a great way to dig in and get some practice!

Using TypeScript in your project has never been easier than it is today. The TypeScript team has continually added features to allow you to reap the benefits of static typing while reducing the overhead to get there.

This course will teach you these new language features TypeScript has to offer. You'll use optional chaining, handle undefined behavior with the unknown type and assertion functions, create private classes, handle tuple (and other data types) types, as well as learn about conditional types.

You'll also learn how to prevent type widening with TypeScript's new const assertions and efficiently type string literals through the use of template literals.

All of these skills will be brought together into examples that Marius will show you how to apply these new TypeScript features to real-world problems.

Skeleton screens show users that content is loading, offering a vague preview of how content will look once it fully loads.

CSS Animations are crucial for the perceived performance purposes since it shows for the user the content is loading by using animations as feedback for whoever is accessing the page.

Follow the steps in this course and you will learn how to create a beautiful and pleasant Skeleton Loader for your web app using CSS animations, focusing on Web Accessibility and Web Semantic.

Learn how to make a fully functioning Tic Tac Toe game that doesn't need any client-side JavaScript!

Learn how to:

• Generate markup with loops and template literals
• Leverage native HTML behavior
• Create SVG
• Use CSS variables and scope
• Implement game logic with HTML forms
• Animate SVG with CSS
• Use CSS Animation to provide motion
• Use Pug Mixins
• Disable motion when users don't want it

• Generate random animations using Pug and CSS variables

Many engineers working with redux have felt burdened by large amounts of boilerplate code and confusing indirection. These apps often rely on legacy patterns that are no longer recommended, but are still commonly found in production code bases. If you are are an engineer working on such an application, this course is for you. In it I will show you how to modernize your application, with react hooks, one component at a time. At the end of it, we'll still be using redux, but the structure and content of your code will be significantly improved.

We will cover migrating class components to functional components with react hooks and how to replace connect() with redux hooks. This course will serve as a good tutorial for learning react hooks. It will also help you apply modern patterns for using redux. These patterns, powered by the new useSelector and useDispatch hooks will transform your redux applications for the better.

In this course, Chris takes a README-driven approach to build out a Rust CLI that supports content authoring for a digital garden.

Specifically, you'll work through the first command for the CLI, writing files. You start by initializing a new Cargo binary crate through creating the write command that allows you to create files (and their contents) to the folder that you set.

Step by step you'll learn about:

• Handling user input
• Error handling
• Rust Move semantics
• Rust Copy semantics
• Integration testing

...and more!

A series of lessons to help you get more familiar with modern JavaScript syntax.

• Web audio APIs include support for features that aren't available by default in the native HTML audio element.
• The operating system includes basic controls
• Custom controls must be accessible with a keyboard, and make sense to a screen reader
• Don't hide the built-in controls until you know that your custom controls are working
• Listening to what VoiceOver reads should inform the a11y information you include
  • VoiceOver says "Elapsed Time" on its own, so we wouldn't want to write it in our code.
• loadedmetadata should have the duration to avoid glitches from new audio not being loaded.
• Elements should be labeled with a unique id

elm-ui is a language for layout and interface design. This is a novel iteration on declarative styling where you can use Elm types and functions to define your UI in a declarative way.

The novel part is that it does not require you to know CSS to be used. The API is very simple and can be learned quickly!

The approach taken by elm-ui is based on two big ideas: Getting the compiler to verify as much of the layout and styling as possible by defining them in Elm code Enabling refactoring capabilities of Elm for UI code

Forms are one of the most common features of a web application. They are also a common cause of headaches. The controls you use, the markup for the structural layout, and the styling all have to be considered.

What you build can look and behave differently depending on the browser being used, and how you build it can impact the accessibility of your application.

Stephanie Eckles has prepared several lessons that work through the creation of a complete form demo featuring the most common controls with a variety of attributes.

You'll create semantic fieldsets, add responsive styles without media queries, and prepare styles for accessible validation.

The demo is built with Sass and Eleventy. Don't worry if you don't have prior experience with these tools— Stephanie's code and explanations make it easy to follow along, and additional resources are available if you need them.

Redux was announced back in 2015 and immediately took off as the de-facto state management solution for React. As it gained widespread traction, it also became clear that in many cases it was brought into applications prematurely. The community in some ways started to push back on its use and recommended the built-in setState method as an alternative. Several other state libraries also started popping up around this time. Finally, as React Hooks were announced with a built-in useReducer method it appeared that Redux's time was up. However, these claims have proven to be premature. Redux is not dead and instead remains React's most popular state management library*.

Recent updates to redux exposing a hooks-based API address some of its most serious drawbacks and make it even more appealing. This course will show you how to apply redux to a modern react hooks application. I hope you leave this course with a continued appreciation for React Hooks and renewed enthusiasm for Redux.

Thanks for watching 📺.

Cloudflare Workers is a serverless application platform that enables you to create and deploy functions to Cloudflare's Edge Network.

Unlike other serverless providers that only have regional data centers, Cloudflare's Edge Network consists of hundreds of servers all over the world.

Cloudflare Workers is a powerful platform, and this course serves as a great introduction for what it can do.

Follow along with Kristian Freeman as you build a localization engine that renders data based on the Edge location nearest to the application's user.

After this course, you'll be ready to start experimenting with your own Cloudflare Workers projects. Need an idea? Check out the suggested Portfolio Project for this course.

The CSS Grid Layout introduces a two-dimensional grid system allowing both fixed and flexible track sizes to be defined. This allows for easy management of an app's layout.

You'll start with an empty HTML file with minimal global styles applied in your CSS file. You will then iteratively add sections and items to your HTML page to structure through a CSS grid. You'll learn how to control a grid's columns and rows and define the size of each respectively.

By the end of the course, you'll have a fully responsive landing page that behaves how you expect it to on any device.

Starting from a prebuilt frontend, Jason Lengstorf guides you through the creation of a "Corgi Up-boop App" that uses Netlify Functions and Hasura. You can view the deployed final product on Netlify.

You'll set up the Netlify CLI, and configure a local development environment before writing and deploying functions with a few different use cases.

The first example function bypasses CORS restrictions to retrieve corgi data from an example third-party API.

Next, you'll configure environmental variables to securely communicate with the Unsplash API without exposing private keys to the client.

Serverless functions don't persist data by themselves, so we will use Hasura to create a GraphQL API for tracking the number of "boops" each corgi receives.

This course is an excellent illustration of the speed of Serverless functions, and how fast you can implement functionality in your web applications.

How to create buttons in React Native depending on the level of desired customisability: the quick and simple Button, a more customisable Touchable, and the most customisable Pressable.

Button component is useful for quick prototyping.

TouchableOpacity is the most common way of creating buttons and other touchable areas, and is suitable for most use cases.

Pressable gives you the most control over the look and feel of your button, including customising the pressed state and text, as well as handling long presses separately from regular presses.

Accept payments & sell products powered by Stripe and the best of the JAMStack

There are as many ways to build an e-commerce store on the internet as there are products to sell. One thing is for certain, e-commerce is here to stay and as professional developers we need to understand how to build fully custom stores for our clients using the best modern tools available.

• React: flexible and customizable while following modern best practices
• Next.js: lightening fast with guide rails to help your project perform as consumers expect
• Stripe Checkout: lets you offload reams of complicated business logic to a trusted third party that maintains regulatory compliance, global payments, and a standard UX.

Your store will have well managed local component state using React Hooks and you'll also have clear and cohesive shared (global) state with React Context.

Finally you'll deploy your custom store to Vercel (the platform behind Next.js) as well as how to make your Next.js e-commerce store portable to deploy to other platforms.

Learn how to use the AWS Cloud Development Kit (CDK) to create and deploy a DynamoDB table with Next.js.

While "It works on my computer" might give you an excuse to close a bug ticket in the backlog, it doesn't really work when you're working on a team.

You need to ensure that your application can run regardless of what hardware your teammates are running or libraries they have installed.

Docker solves this problem by collecting everything your application needs to run into a container.

Containers aren't just for source code. They can hold configuration, scripts, and even their own filesystem. It's similar to a Virtual Machine, without having to bring a full operating system along for the ride.

Because containers run in isolation, there is some configuration involved to allow for files to be saved and containers to communicate with one another.

One of the most useful ways to get your head around Docker is to see it in action.

Follow along with Joel Lord as he works through the process of preparing an application to run in separate containers for the frontend and backend of an application that searches for gifs and re-encodes them with a caption supplied by the user.

You'll see how to configure the separate containers to communicate with one another, work with environment variables, and persist data to your local machine. Along the way, you'll pick up some tips on useful commands and bash scripting. Finally, you'll learn how to use Docker Compose to make it easy to run multiple containers simultaneously.

WordPress has been around for a long time and powers a huge number of sites.

Just because WordPress isn't brand new doesn't mean it can't get the job done!

Running WordPress as a Headless CMS gives you the benefit of a great content creation experience on the back end with the powerful Gutenberg editor while allowing you to use a modern JavaScript framework on the front-end.

In this course, Kevin Cunningham will guide you through setting up WordPress as a headless CMS from scratch, as well as migrating from an existing WP site. You'll get practice with different WordPress content types, implement a GraphQL endpoint for querying data, and backup & deploy your site. All the while, you'll deepen your understanding of how headless WordPress approaches the relationship between content & rendering.

Using WordPress as a headless CMS turns it into a datasource ready to work with Gatsby, Next.js, or whatever else you want to build with. Your and your clients will be able to take advantage of WordPress's content editing experience, without having to settle for a cookie-cutter theme on the frontend.

With WordPress being decoupled from the rendered site, the database isn't hit for every request. This means faster performance and more security against WordPress exploits. You don't even have to host the editor at the same domain as the published site.

While watching, consider...

• What are the tradeoffs of using a CMS for a site?
• Would headless WordPress work for me or my clients in this scenario?

Managing state in a UI is challenging. It's genuinely difficult and the solutions require a depth of knowledge and experience to understand. Everything is a balance of tradeoffs in complexity, performance, and user experience.

This is a series of interviews with experts, open-source maintainers, and UI developers that have combined decades of experience building stateful UI applications for millions of users.

Part interview, part screen share, these videos should benefit you if you're building web applications.

They focus on React, but the underlying principles are valid for UI work in general (and beyond).

On the surface, starting a project sounds easy. First you make some directories, install some dependencies, then you write some code.

But there's a bit more to it than just those three steps.

The type of project you're working on impacts the decisions you make. It gets more complicated when you're working on multiple projects that are related. For example, maybe you have a customer-facing frontend app, an admin dashboard app, and a single backend used for both.

How does this change your directory structures? How should you share code between projects? What happens when you add a Design System into the mix?

It can get hard to keep things straight in your head.

Nx is a tool that aims to solve these problems for you, whether you're working solo on a small full-stack app or on a dev team of thousands.

It's not just an opinionated folder structure. When you create an app with Nx, it generates unit and e2e test setups as well as preparing bundling and code-splitting with Webpack, and stubbing out common features like routing.

One of the coolest features of Nx is its Dependency Graph. The graph can visually show you the relationship between the parts of your application, and is optimized to ensure that compiling, testing, and linting only happens in the affected areas of your project.

In this course, Juri Strumpflohner demonstrates these features and more through the iterative creation of a React + Storybook + Express app. Don't worry if this isn't your preferred stack! Nx supports the most popular frameworks & libraries on the web.

More importantly, the focus of this course is more on the workflow than the implementation.

Watch Juri's course, and see if the Nx tooling & workflow is right for you and your team!

The new React Hooks API allows using different patterns in a simple, direct, and functional way.

In this course, you will find a step-by-step guide to build a complex component using different design patterns implemented with the Hooks API.

We will start with a simple component <Wizard> that uses the useState hook and in each lesson, we will be improving the implementation by using different strategies.

In the last lessons, we will have a full Wizard component with a flexible API to allow the user to manage the component based on their requirements and You will have learned the use of useState, useReducer, useContext, useEffect and useCallback along with some popular design patterns to build React applications.

You will be able to find the code and notes for each lesson in the GitHub repository.

Techniques to improve your CSS, Sass, and HTML implementations for everyday scenarios.

Learn how to create tuples in Python. The videos in this collection will also cover more advanced features of tuples

As a developer, you'll often make use of APIs that have you pass in a callback function. For example, adding event listeners or using various other DOM or Node APIs.

What's less common is writing your own code that makes use of callbacks. Many developers know what a callback is, but not the why or how of implementing them in their projects.

A callback is a function that you pass to another function, so that the function that you pass it to controls the invocation of that function.

To help keep things straight, John Lindquist calls the innermost callback the Listener, and the function it gets passed into the Broadcaster.

Think of it as one function broadcasting values to another function that is listening for them.

These Broadcaster-Listener callback relationships can be composed to solve problems in the realm of timing, buffering, and caching.

This pattern of composing callbacks is the foundation of RxJS and other libraries that handle complex async scenarios.

In this course, John Lindquist guides you from a blank JavaScript file all the way through creating a library of reusable functions not unlike those found in RxJS. The difference is you'll be writing from scratch.

You'll learn techniques for solving Callback Hell with composition, implementing debouncing, and building a word game among several other examples.

Using callbacks in code is a major pattern in JavaScript, and learning to work with them effectively will take your problem-solving skills to the next level.
