Resources for Web Developers in 2021

This is a list of web components lessons showing the technologies behind it and some practical ways to use it now in production.

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.

GraphQL is gaining traction as one of the most popular ways to create an API. Regardless of which GraphQL implementation you pick, you’ll use the QL in GraphQL — the query language — to query data, change data with mutations, and listen for data changes with subscriptions.

You need to know the Query Language regardless of the server-side implementation.  In this course, we will learn the GraphQL query language by sending an assortment of GraphQL operations to an existing API. 

To start, we’ll learn how to write queries to obtain all the data needed for an app in one response. As the course progresses, we’ll use mutations to add and change data. To wrap up, we’ll investigate GraphQL subscriptions and realtime data. 

After the course, you’ll be ready to communicate with a GraphQL API regardless of server-side implementation using the GraphQL query language.

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.

In this collection of lessons we will create a developer dashboard in the terminal using react-blessed and react-blessed-contrib. We will discuss various ways to layout the dashboard, show how to change fonts, style with colors, and position text within each widget. Then we will shift focus on creating some widgets to display developer content such as an interactive time log, a pomodoro timer, displaying recent commits, currently running docker containers, and more. Once you know the basics you can create a widget of your own to add to the dashboard.

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.

Extracting meaningful data from strings is a crucial skill when working with bash, and bash gives us powerful tools to do so: `head`, `tail`, `cut`, `sed`, and `awk`. But these tools can be hard to understand without spending time to learn them, so many developers fall into a rut of blindly copying and pasting commands. No more! With this mini-course, you'll understand the basic ins and outs of these commands in under 15 minutes. 


Bash is a Unix shell and command language written by Brian Fox for the GNU Project as a free software replacement for the Bourne shell. Bash is a command processor that typically runs in a text window, where the user types commands that cause actions. Bash can also read and execute commands from a file, called a shell script.

Gatsby Themes are the next iteration of web development. They take all the good things about Gatsby and make them even more reusable and extendable. Themes are composable chunks of fully functional websites-- not just visual aspects.

Because they’re composable, you can have multiple themes on a single site. This lets you pick the right eCommerce theme, with whatever backing engine you want. You can then install whatever blog theme you want-- Wordpress, Contentful, etc. and you can customize them both. It's up to you!

For a written version of this course, check out the [Gatsby docs](https://www.gatsbyjs.org/tutorial/building-a-theme/).

Gatsby is a blazing fast static site generator built with React. Gatsby gives you all of the modern JavaScript tools you want; set up and ready to go out of the box.

Imagine the following.

You join a new project and after getting access to the repo you notice that there's no tests.

You decide to ask the team whether they are in different repo or something and unfortunately the answer is:

>We don't have any tests, we didn't have the time.

In this collection we're going to learn how to add e2e tests with cypress.io to an existing React app in order to do two things:

- 🌟 Ensure that our app currently works as intended
- 🌟 Allow us to add features to it with a technique called "Cypress Driven Development" 

In less than 20 minutes we're going to go through:

- ⚡️Adding cypress.io setup to an existing project
- ⚡️Testing search functionality with `data-cy` properties
- ⚡️Using "Cypress Driven Development" to add a new feature to an app
- ⚡️Use Cypress UI to debug an API response
- ⚡️How to use `cy.only` and `cy.skip` in order for us to build our e2e test suite faster

and much more!

Fast, easy and reliable testing for anything that runs in a browser.

We generally tend to avoid paying for things unless we actually need them, and the same goes for AWS

When using a cloud provider like AWS sometimes an unexpected charge may occur and we'd like to understand what are we being charged for and how to be notified whenever an unexpected charge occurs (especially when we're trying to stay within a free tier).

In this quick (4 minutes, 2 lessons) collection we're going to learn how to:

- Review the AWS Billing & Cost Management Dashboard
- Set up a billing alarm to be notified whenever our bill is larger than $5
- Review the AWS bill to understand how much are we going to pay this month and why

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.

SSH provides a secure way for your to [connect to and authenticate with GitHub's servers](https://help.github.com/en/github/authenticating-to-github/about-ssh). While HTTPS connections use usernames and passwords as credentials, SSH instead uses public and private key pairs. These can be generated on your system using a CLI like [`ssh-keygen`](https://help.github.com/en/github/authenticating-to-github/generating-a-new-ssh-key-and-adding-it-to-the-ssh-agent) and then associated with your GitHub account using the public key.

In some cases, you may need to connect to more than one GitHub account from the same system. For example, you may have [separate accounts for personal and professional projects](https://ryanharris.dev/managing-ssh-keys-for-github/), which can be difficult to manage manually. Using `ssh-agent` and a SSH configuration file, you can alleviate this pain point by automatically determining which key to use based on your GitHub repository's `git` URL.

Github Actions are an awesome tool from Github that allows us to automate tasks using code-based workflow configuration files. There's also a large marketplace that comes stocked with many useful tools that are ready out of the box.

But sometimes the options available don't completely solve our needs or maybe we're working with a new technology that's simply not available as an Action yet. Luckily, Github allows anyone to create their own Actions using common technologies like Javascript via Node.

We'll learn how to create a new Javascript-based Github Action running on Node. We'll first walk through a simple Hello World example, learn how to test it locally, version control it, use it in the wild, and move on to more advanced solutions that include using packages from npm!

GitHub fosters a fast, flexible, and collaborative development process that lets you work on your own or with others.

It's tempting to pick up a framework which has preselected flexbox or grid as the layout tool of choice, but it's important to learn when and why to use each method. This leads to slimmer stylesheets which results in better site performance, and less likelihood for "hacks" to make one method do what the other does inherently better.

Throughout this collection, we will be progressively styling a responsive landing page template while building your knowledge on when to select grid or flexbox for any layout scenario. Spoiler alert: sometimes the best solution is using both!

The specification describes a CSS box model optimized for user interface design. In the flex layout model, the children of a flex container can be laid out in any direction, and can “flex” their sizes, either growing to fill unused space or shrinking to avoid overflowing the parent.

Welcome to this beginner level series on Alpine JS! 👋🏞

Alpine JS is a rugged, minimal framework for composing JavaScript behaviour in your markup. It brings declarative, reactive, data-driven nature of libraries like React or Vue to your HTML templates.

In this series, you will learn about Alpine's handy **directives**. You'll discover how to define a component scope with `x-data`, run code on mount with `x-init`, attach event listeners with `x-on`, display data with `x-text`, decide wether or not to show an element with `x-show`, iterate through data with `x-for`, retrieve a DOM element with `x-ref`, learn how to achieve _two-way data binding_ with `x-model`, and much more.

You'll also learn how **"modifiers"** can be applied and chained to directives to provide additional functionality: control the animation transition of entering and leaving DOM elements, debounce an event listener, etc.

We'll also touch on what Alpine calls **"magic properties"**, which give you access to native browser events (`$event`), reference to DOM elements (`$refs`), and more.

You'll gradually discover Alpine's API and syntax, from building simple tabs to a mini app that fetches a dog picture based on a "breed" search field. 🐶

**Get ready to breathe some fresh air** - it's time to walk into cool, green Alpine pastures! 🏞

Alpine.js offers you the reactive and declarative nature of big frameworks like Vue or React at a much lower cost.

You get to keep your DOM, and sprinkle in behavior as you see fit.

The JAMstack, short for “JavaScript, APIs, and Markup,” has been making waves in the world of web development. 

Building JAMstack applications removes the hassle of building out a backend from scratch, freeing you to focus on what really matters: your content.

In this course, you’ll learn how to build and deploy your own static Gatsby site that pulls external data from Contentful and then deploys to the web with Netlify. After the course, you’ll have all the knowledge you need to build a blog, marketing site, or portfolio with Gatsby. Just add content.


Check out these [**community notes for this course on Github**](https://github.com/eggheadio-projects/build-content-rich-progressive-web-apps-with-gatsby-and-contentful-notes).

Build Content Rich Progressive Web Apps with Gatsby and Contentful

Modern applications know how to keep users informed of realtime updates through notifications, popups, and other messages.

On the development side, the ability to not only create web apps but have them communicate in realtime is a quirky, standout skill for your resume. It’s interesting, useful, and powerful.

In this course, Mark Barton will show you how to use Socket.io to facilitate bi-directional client-server communication and notifications using Vue on the frontend. Socket.io is a JS library that connects a client-side library to a node.js server. In the course, you’ll see how to use Socket.io to broadcast simultaneously to all or targeted clients based on filters you set up — so the right people see the right message at the right time.

You’ll learn to set up and connect Socket.io with node.js and Vue, and you’ll get practice making informed, complex architectural decisions around realtime broadcast messaging.

Vue (pronounced /vjuː/, like view) is a progressive framework for building user interfaces. Unlike other monolithic frameworks, Vue is designed from the ground up to be incrementally adoptable. The core library is focused on the view layer only, and is very easy to pick up and integrate with other libraries or existing projects. On the other hand, Vue is also perfectly capable of powering sophisticated Single-Page Applications when used in combination with modern tooling and supporting libraries.

Vue and Socket.io for Real-Time Communication

One of the most important — but most ignored — practices for web developers is performing end-to-end testing on applications before they go live into production. You know: making sure they work like they’re supposed to. But testing can be tedious, and definitely not fun.

In this course, Brett Cassette will show you how you can test all layers of your application stack, simultaneously, with Cypress. When you use Cypress, it’s like having a robot that uses your app the way a real user would. Cypress reports if things work the way you designed them to — and if they don’t — every step of the way. And it’s fun.

After completing this course, you’ll be ready to apply the same E2E testing principles to your own applications. Stop leaning on your QA department (if it exists) to stress-test your application, and ship your app knowing it’s ready. 


Test Production Ready Apps with Cypress

Learn how to build a simple REST API to store notes using the latest built-in node features including native ES modules, the fs/promises API, async/await, the nullish coalescing operator, and destructuring. No compilers, no build steps, pure code.

This collection of lessons is great for beginners to Express as long as they are familiar with JavaScript and the HTTP protocol. Those more familiar with node and express will appreciate a fast-paced, modern take on using these popular tools and will likely benefit most from the lessons on input validation, models (which emphasizes a lot of new syntax), using fs/promises to serialize a `Map`, and accessing asynchronous data with `async/await`.

Pre-requisites:

- [Install curl](https://curl.haxx.se/)
- [Install node 14](http://nodejs.org/)
- Be familiar with the terminal

View the source for this project in the [project's github repo](https://github.com/xjamundx/egghead-express).

**Notes**:

- I'm not very pedantic about REST and basically just mean an API over HTTP
- [Express 5](https://expressjs.com/en/guide/migrating-5.html) is still in alpha (and has been for over two years), but most of these lessons apply to Express 4 as long you use something like [express-async-errors](https://www.npmjs.com/package/express-async-errors) to add support for `async` routes and middleware

Express is a minimal and flexible Node.js web application framework that provides a robust set of features for web and mobile applications.

There are many ways to build a new website, but it can often be a slow, painful process for both beginners and those who have been working in the field for a long time.

With the modern tooling in the Jamstack world, we can take advantage of tools like Gatsby that can allow us to rapidly spin up a new project and TakeShape that can provide us with an all-inclusive content management system (CMS) to focus on the important parts of what makes our websites unique. 

In this collection, we'll walk through building a new company website from scratch. After creating a new example project in TakeShape, we'll use the TakeShape API to fetch that data and dynamically build a website using a Gatsby Starter for a TakeShape Startup project. With your new website, we'll learn how we can customize it to make it your own by adding new content and changing the branding like the logo and colors.

Whether you enjoy CSS animations or not, learning how to work with CSS transforms and transitions can help the overall user experience on your websites.

In this collection we will look at the various CSS properties that help create the kind of experience user have come to expect from websites. 

We will explore:
- The transform property
- The transition property


Cascading Style Sheets bring order and beauty to our applications.

Recoil is a new (experimental!) library from facebook that can handle complex shared data across a large react app.

In this collection, we'll create a simple game with React using Recoil, to explore how you can share and update state across an app.

Recoil is similar to (but different than) Context, Redux, or other shared state libraries (like MobX), but is designed to handle large (and variable) numbers of state that can update without re-rendering your entire app's component tree.
