Resources for Web Developers in 2022

ES2015 brought a native Promise to the JavaScript standard library. In this course, we’re going to take an in-depth look at how to use promises to model various kinds of asynchronous operations.

First, we’re going to explore how to create promises using the Promise constructor or the Promise.resolve() or Promise.reject() methods. Then, we’re going to see how to chain promises together using .then(), .catch(), and .finally(). We’re going to compare various error handling strategies along the way. We’re going to wrap up this course by taking a look at how to deal with multiple promises using Promise.all() and Promise.race() and how to await a promise using the await operator.

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.

Knowing your everyday toolset increases your productivity as a developer. And Git is one of those tools you use on a daily basis. Mastering Git is tough; it has hundreds of different commands, often even inconsistent at how you pass in flags and configuration options. On the other side, there are a lot of good Git courses out there already, explaining all of these commands in detail. 

With this course, I aim at a different goal. You will walk through a series of scenarios which you’ll most commonly encounter in your daily work life as a developer. I’m talking:
 - updating your feature branch with the latest changes from master
 - polishing your git history to make it ready for being peer-reviewed
 - moving a set of commits to another branch
 - undoing accidental commits

The goal is not to cover everything, but those tasks that will greatly improve your daily productivity with Git.


Git is a free and open source distributed version control system designed to handle everything from small to very large projects with speed and efficiency.

Bash makes automation easy. Just a few lines of code can take care of repetitive tasks for you and your teammates. 

In this course, we’ll dive deep into the automation potential of bash. You’ll learn to leverage common hooks that open up interesting automation possibilities, like git hooks, adding functions and aliases in your bash_profile, and running scheduled jobs in launchd.

For example, we’ll write a git hook that checks package.json for changes, and if there are changes, the hook runs npm install for you automatically. 

Along the way, you’ll also learn:

- more advanced bash commands like exec
- syntax such as redirecting stdout and stderr to the same destination
- timesaving tricks like brace expansions

Automation is all about saving you time — and at only 52 minutes, this course is well worth yours. Enjoy!

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.

On many websites, images and video make up the vast bulk of the data being sent over the wire; websites will often have _several megabytes_ of images!

There's a lot of low-hanging fruit in this area. In this collection, we'll learn how to convert our images to the `webp` format—a format often **2-3x smaller** than png/jpg—and how to use the `picture` element to ensure graceful fallback on unsupported browsers. We'll see how to come up with a great abstraction for React to make it as painless to use as possible.

Later in this collection, we'll also cover:
- Automatically generating webp images on build
- Leveraging `gatsby-image` to do the same thing in Gatsby
- Smaller images across the browser spectrum with jpeg2000 and jpegxr
- Avoiding layout problems with `display: contents`
- Smaller video with `webm` instead of `mp4`

WordPress is the most popular content management system in the world. Content creators are able to easily customize nearly everything about WordPress from their admin dashboard, providing a really pleasant content management experience. Using Gatsby as a frontend for your WordPress sites makes the experience of developing the site and visiting the site just as pleasant.

Moving your WordPress frontend to the Jamstack means you keep the convenience of using WordPress’s custom backend for creating and editing content while _also_ avoiding some of WordPress’s biggest downsides.

Historically, WordPress has many downsides, including:

- **Security** — because it’s the most popular content management system in the world, hackers work hard to find and exploit security holes in WordPress sites.
Performance — through a combination of legacy code, community plugins, and other challenges, WordPress sites can easily become slow to load.
- **Scale** — if a WordPress site suddenly becomes very popular (a great thing!) it can overload servers and cause the website to go down (a not-so-great thing!) without complex scaling techniques.
- **Cost** — a WordPress site requires always-on hosting, and specialized hosting can be expensive. Adding support to handle massive scale adds significant cost, too.

Switching to the Jamstack helps mitigate — and even eliminate! — these downsides:

- **More secure** — Jamstack sites don’t connect to the server or database after they’re built. This makes it much harder to hack the site.
- **More performant** — by doing less work for each request and leveraging modern tools, Jamstack sites tend to outperform WordPress sites out of the box, and can be very fast with a bit of extra effort.
- **More resilient** — because Jamstack sites ship to a content delivery network (CDN) by default, a sudden surge of site visitors won’t take your site down.
- **More affordable** — many Jamstack hosting solutions have generous free tiers that are plenty for most small to medium sites, and upgraded accounts typically cost less than specialized WordPress hosting.

Switching to the Jamstack gives you all of the benefits of WordPress and helps you avoid the downsides!

In this collection, we walk through the full process of migrating a WordPress site to the Jamstack, which keeps all the flexibility and power of WordPress’s admin dashboards while adding all the benefits of the Jamstack.

Migrate a WordPress Site to the Jamstack Using Gatsby

In many cases, teams reach for Redux as the de facto choice for state management. But sometimes, Redux is overkill. In those cases, the React Context API might suit your needs perfectly.

In this course, we’ll build a simple email client using the React Context API to pass data throughout the app. You’ll learn how to create a context, how to pass data deeply through an app without manually passing props all over the place, and how to group related data and logic using simple wrapper components. We’ll also cover practical applications like using Context to display and manage notifications, how to maximize performance with Context, and how to test the components that use it to ensure your app is working properly.

React Context for State Management


React got that name for a reason. It’s a component-based JavaScript library that renders smartly and can seriously simplify your work.

This course is for React newbies and anyone looking to build a solid foundation. It’s designed to teach you everything you need to start building web applications in React right away.

Each lesson in this 19-part course is a single index.html file. This keeps your focus on learning React, no distractions. We’ll start with a blank file and add more complexity as we go along, wrapping the course with a lesson on how to move into a more production-ready development environment—and even deploy your app to a great service like Netlify.

You'll come out of this course with a solid grasp on:

what problems React can solve
how React solves those problems under the hood
what JSX is and how it translates to regular JavaScript function calls and objects
You’ll build a solid understanding so when you come across JavaScript challenges down the road, you’ll know how to…react.
