Resources for Web Developers in 2022

In this free collection on Facebook's new state management library, we'll get started using Recoil in our React applications and then delve into various common use cases that we may encounter in the field.

We'll start with the basics of state management in Recoil: the Atoms and Selectors. Then we'll dive further into the Selector API, an important part of the library. Along the way we'll learn different strategies for handling synchronous and asynchronous Selectors.

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

If you know what you’re doing, React can drastically simplify how you build, use, and maintain code.

Whether you’re a React newbie or you’re ready for advanced techniques, you can level-up with egghead. Explore our in-depth courses, lessons, and community resources to build more powerful applications and crack open your career.

Learn how to create dynamic front ends using both Cloudflare Pages and Cloudflare Workers. 

With Cloudflare Pages, you can deploy static sites in seconds from Github. In this course, you will learn how to get started by going through the setup process and integrating Contentful and Airtable. 

And we will the frontend dynamic by writing a serverless function with Cloudflare Workers. We set that up by using the Cloudflare Workers CLI, Wrangler, which makes it easy to connect to your Cloudflare account and create serverless functions. 

And then we connect them with our example project, where we need to send submitted form data from our front end over to Airtable. 

So check out this course and learn to use the Jamstack with Cloudflare today!

Cloudflare secures and ensures the reliability of your external-facing resources such as websites, APIs, and applications. It protects your internal resources such as behind-the-firewall applications, teams, and devices. And it is your platform for developing globally-scalable applications.

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.

If you're a web developer who has been itching to get into native development, now is your chance. In this series we'll be talking all about React Native. React Native allows you to build native iOS and Android applications in JavaScript and React.js. 

Regardless of your experience with React, or even with iOS development, my hope is that this series will be beneficial to everyone who is starting out with React Native. We'll jump straight into developing with React Native by looking first at the ecosystem of building React Native apps - including  Xcode, the iPhone simulator, live reload, debugging, and more. 

Once we get our ecosystem set up and our hello world example running using ES5, we'll jump straight into building a fully functioning iPhone app which utilizes many of the best parts of developing with React Native all while covering React.js and refactor to ES6 along the way.

React Native lets you build mobile apps using only JavaScript. It uses the same design as React, letting you compose a rich mobile UI from declarative components.

Javascript offers different ways to work with arrays one of the most used data structures out there.

Learn some of these methods and functions to improve the way you manipulate arrays in your code.

JavaScript® (often shortened to JS) is a lightweight, interpreted, object-oriented language with first-class functions, most known as the scripting language for Web pages, but used in many non-browser environments as well such as node.js or Apache CouchDB. It is a prototype-based, multi-paradigm scripting language that is dynamic, and supports object-oriented, imperative, and functional programming styles.

Redux was [announced back in 2015](https://www.youtube.com/watch?v=xsSnOQynTHs) 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](https://react-redux.js.org/api/hooks) 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 📺.

***Note: Some of the RxJS syntax used in this course is outdated, but the concepts taught on arrays, async, and observables are still reliable and applicable.***

Async programming may seem daunting. How can we write programs that accept user input, run animations, and send server requests over the same period? How do we keep the code clear and concise? How do we gracefully propagate and handle asynchronous errors? How can we avoid memory leaks caused by dangling event handlers? JavaScript's loops and try/catch keywords are no help - they only work on synchronous functions.

Here's the good news: Asynchronous programming is much easier than it seems. The key is to think differently about events. It is possible to build most asynchronous programs using a handful of simple functions. We will learn why most JavaScript developers approach asynchronous programming the wrong way, and how to avoid these common mistakes. 

RxJS is a library for composing asynchronous and event-based programs by using observable sequences.

Start from a blank project and build up to an Eleventy site that includes a blog collection and is prepared to source content from a headless CMS. You'll also learn how to add Sass as the styling solution, complete with triggering 11ty to re-compile when the Sass changes.

These lessons will help explain key 11ty features and concepts to help you make the most of this amazing static site generator.

By the last lesson, you'll have learned how to:
- define custom `input` and `output` directories
- create a layout that accesses front matter variables
- watch for Sass changes and include CSS in the build proces
- create an 11ty collection using `tags`
- define front matter for an entire collection
- make and apply a filter to a collection
- generate pages from an external data source, such as a CMS or API

Eleventy was created to be a JavaScript alternative to Jekyll. It’s zero-config by default but has flexible configuration options. Eleventy works with your project’s existing directory structure.

Eleventy uses independent template engines. We don’t want to hold your content hostage. If you decide to use something else later, having your content decoupled in this way will make migration easier.

Some introductory lessons on Webpack (webpack.github.io). Not tied to any particular framework.

webpack is a tool to build JavaScript modules in your application. To start using webpack from its cli or api, follow the Installation instructions. webpack simplifies your workflow by quickly constructing a dependency graph of your application and bundling them in the right order. webpack can be configured to customise optimisations to your code, to split vendor/css/js code for production, run a development server that hot-reloads your code without page refresh and many such cool features.

**Data** is the bedrock of any application, including your AngularJS project. This series will dive deep into data models, and how to effectively use them in your applications. 

AngularJS's solution out of the box is $resource, but this service isn't always the best solution. Many times we need a custom model layer that serves the needs of our application. This series explores building a $resource alternative from scratch using TDD.

It's intended for **intermediate-advanced AngularJS developers** that want to dig a little deeper to lower level abstractions for core systems in their applications.

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 Data Modeling

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!

Amazon Web Services (AWS) is a powerful expansive cloud infrastructure platform for building modern web applications.

AWS provides services for data, presentation, authentication, security, video encoding, and much more. Offering over 175 fully-featured services from data centers globally, AWS powers a large percentage of the internet.

JSON Web Tokens (JWT) are a more modern approach to authentication. As the web moves to a greater separation between the client and server, JWT provides a terrific alternative to traditional cookie based authentication models. For more information on JWT visit http://jwt.io/

In this series, we’ll be building a simple application to get random user information from a node server with an Angular client. We’ll then implement JWT to protect the random user resource on the server and then work through the frontend to get JWT authentication working.

By the end, we’ll have an application which has a single username/password combination (for simplicity) and uses tokens to authorize the client to see the random user information. You’ll be able to login, get random users, and logout.

AngularJS Authentication with JWT

Creating forms is one of the simplest and most complicated things at the same time. A basic form consists of many different things happening, we have to retain the value, we have to keep watch of validation and we have to show error messages when something is invalid, this is on both the fields and on the entire form itself if we send a request off to the backend service.

So we're going to create a form using just the normal svelte features. Then we'll look into creating a form using the svelte forms lib. 

The magical disappearing UI framework

 - The web's JavaScript bloat crisis, solved. Svelte turns your templates into tiny, framework-less vanilla JavaScript.
 - Simple and familiar. Build apps out of composable, easy-to-write blocks using languages you already know.
 - Super fast, rock solid. Compile-time static analysis ensures the browser does no more work than it needs to.

This collection of videos teaches you how to use [KeystoneJS](https://v5.keystonejs.com) to build a CRUD-ready GraphQL API, coming with an automatically generated Admin UI. 

Starting with a blank file, we will create an API by:
- defining "Lists" as content types
- adding fields (Select, Text, Checkbox, ...) to our lists
- customising access control to define what users can (and cannot!) do with our API.

GraphQL is a query language for APIs and a runtime for fulfilling those queries with your existing data. GraphQL provides a complete and understandable description of the data in your API, gives clients the power to ask for exactly what they need and nothing more, makes it easier to evolve APIs over time, and enables powerful developer tools.
