Resources for Web Developers in 2022

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.

React is one of the web’s most popular frameworks for building JavaScript applications.

The definition of "legacy code" can be described simply as "code that doesn't have tests." Code you just wrote, 5 minutes ago? Legacy code. Code that can't be **refactored**, but only changed.

How do we prevent the mountain of legacy code that most projects become?

A solid testing strategy.

React apps are no different, and can be tested simply if you know some core principles.

In this course we will take a look at testing React applications. From getting setup and running tests, all the way through testing Redux enabled React applications.

In this comprehensive tutorial, Dan Abramov - the creator of Redux - will teach you how to manage state in your [React](/q/react) application with [Redux](/q/redux). 

[State management](https://egghead.io/playlists/react-state-management-in-2021-6732) is absolutely critical in providing users with a well-crafted experience with minimal bugs. 

It's also one of the hardest aspects of a modern front-end application to get right.

Redux provides a solid, stable, and mature solution to managing state in your React application. Through a handful of small, useful patterns, Redux can transform your application from a total mess of confusing and scattered state, into a delightfully organized, easy to understand modern [JavaScript](/q/javascript) powerhouse.

The principles of Redux aren't new, but they are packaged and presented for you in an easy to use a library that not only elevates your applications but also improves your general understanding of building JavaScript UIs.

In this course, Dan Abramov will show you the fundamentals of Redux, so that you can start using it to simplify your applications. 

There are some amazing [community notes on this course here on Github](https://github.com/tayiorbeii/egghead.io_redux_course_notes).

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

![todo-app-screenshot](https://res.cloudinary.com/dg3gyk0gu/image/upload/v1639014074/course-resources/Build-data-driven-applications-on-the-edge-with-Workers-and-Workers-KV/CleanShot_2021-12-08_at_16.46.39_2x.png)

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](https://egghead.io/courses/introduction-to-cloudflare-workers-5aa3) to get a better understanding of how Workers KV comes into play.

## 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

![https://res.cloudinary.com/dg3gyk0gu/video/upload/e_loop/q_100/v1639426695/course-resources/refactor-react-components-to-typescript-c70bffa0/landing-page-gif.gif](https://res.cloudinary.com/dg3gyk0gu/video/upload/e_loop/q_100/v1639426695/course-resources/refactor-react-components-to-typescript-c70bffa0/landing-page-gif.gif)

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](https://egghead.io/courses/the-beginner-s-guide-to-react) and [Up and Running with TypeScript](https://egghead.io/courses/up-and-running-with-typescript) are the best two places to start. 

## What's Next?

**[The Beginner's Guide to React](https://egghead.io/courses/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](https://egghead.io/courses/advanced-typescript-fundamentals-579c174f)** 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](https://egghead.io/courses/typescript-tips-and-tricks-20c4) 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.

Refactor a React Application to TypeScript

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.

Next.js is a minimalistic framework for server-rendered React applications.

How to Extend a GraphQL API

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. 

Modern Redux with Redux Toolkit (RTK) and TypeScript

One of the fundamental concepts for building a successful large-scale application is breaking it down into smaller, potentially independent, but mainly more controllable and maintainable parts. This starts at the component level, the module level, and finally the application routing level. Routing is a core part of every application—it should be part of every developer’s tool belt.

This course will guide you step-by-step from understanding the basic concepts of routing to mastering expert-level topics. We'll start by setting up and configuring the router, then define simple routes and child routes and best practices of organizing them using the Routing Module pattern. 

You'll learn about the supported URL types and its segments, how to define them, and how to leverage RxJS Observables for subscribing to route updates. We'll also learn how to secure routes with various types of guards and about performance tuning with the router’s lazy loading and preloading capabilities.

Angular is a development platform for creating applications using modern web standards. Angular includes a wealth of essential features such as mobile gestures, animations, filtering, routing, data binding, security, internationalization, and beautiful UI components. It's extremely modular, lightweight, and easy to learn.

Learn Angular Router for Real-World Applications

Supabase is an open-source tool for rapidly building application backends with real-time data and authentication. In this course, you'll learn the fundamentals of Supabase. You'll learn how to model complex data using PostgreSQL and SQL, build authentication flows with Oauth, and add real-time data to a Next.js application to build a fully-featured chat application, similar to Discord.

The chat app will have different "channels," which will be powered by data inside of Supabase. Users can visit these channels and write messages, which will be sent in real-time to other current users of the platform.

After this course, you will be able to model real-world scenarios in actual relational databases, understand how to manage real-time data, and leverage key functionality provided by Supabase, such as authentication, instant APIs, and real-time subscriptions.

Supabase is an open source Firebase alternative. A service to:

- Listen to database changes.
- Query your tables, including filtering, pagination, and deeply nested relationships (like GraphQL).
- Create, update, and delete rows.
- Manage your users and their permissions.
- Interact with your database using a simple UI.

Supabase is not a 1-to-1 mapping of Firebase. Most notably, Supabase uses Postgres rather than a NoSQL store.

Angular is basically a collection of Components brought together within modules. The many tools, such as the Angular CLI, allow you to easily create Components. The key to understanding Angular is understanding how Components interact with each other through Services, Inputs, and Outputs. It's also essential to understand the basics of styling components and how CSS is shared so you can make your application look the way you want.

This course will step us through creating a simple Angular application starting with the Angular CLI. We will build out a few components that will handle events through Angular Event handlers. The course will then finish up with styling the application.

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](https://reactjs.org/docs/hooks-reference.html) and how to replace `connect()` with [redux hooks](https://react-redux.js.org/api/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](https://react-redux.js.org/api/hooks#useselector) and [useDispatch](https://react-redux.js.org/api/hooks#usedispatch) hooks will transform your redux applications for the better. 

Modernizing a Legacy Redux Application with React Hooks

One challenge when learning AngularJS is that most examples are trivial. It is difficult to find materials on learning "real-world" patterns and practices.

The joy of Angular is that you are free to build an application in any form that you wish. MCV, MVVM, MVP, MV*whatever*... You get to decide! Freedom is wonderful. 

"But what if I choose poorly?"

Good question.

This series will demonstrate how to organize and tool your AngularJS application for real work. It's an opinion. A way that has worked on our own projects. Use it as a guide for building the solution that best suits the needs of your projects. All projects are different, but with the right set of modular tools you can build a foundation for success.

Building on the previous series, we are going to refactor Eggly to be modular and scalable. By introducing modules and sub-modules, domain models and state management with ui-router, we will start to establish best practices on how an AngularJS application should not only function, but fit together.

Be sure to check out Part 1: [AngularJS App From Scratch: Getting Started](https://egghead.io/courses/angularjs-app-from-scratch-getting-started)

AngularJS is an open-source JavaScript framework, maintained by Google, that assists with running single-page applications. Its goal is to augment web-based applications with model–view–controller (MVC) capability, in an effort to make both development and testing easier.

AngularJS Application Architecture

Tic Tac Toe is a classic game that has a relatively simple win condition. Get three of your pieces to line up in a row on a 3x3 grid-style board and you win, and also prevent your opponent from doing so.

This makes the game a great challenge to represent as code. 

In this course, you will start with a blank create-react-app application, learn how to build a 3x3 grid (with CSS Grid), and power that grid so that you can take turns with another person and play tic tac toe. 

You'll model the game state as a multidimensional array where you will manage and update that state with `useReducer`
