Resources for Web Developers in 2022

Progressive Web Apps are just Web pages, but with superpowers.  They load under uncertain network conditions, even offline. They’re fast and engaging, providing the best user experience. They can be installed on your smartphone if the browser supports it, feeling like a native app.

In this course I’m gonna show you how to take an existing Single Page App made in Vue.js and pragmatically convert it to a Progressive Web App by creating a web manifest, then it goes through caching static assets, external resources and streams using service workers, applying code-splitting and lazy loading, notifying new versions of the app or wether is online or offline, understanding the preload and precache directives, finishing up by showing how to audit a Progressive Web App.

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.

JavaScript’s dynamic typing makes it incredibly flexible. That flexibility can lead to trouble though. When values have the potential to change types or to end up as `null` or `undefined`, that can lead to runtime errors in our code or bizarre bugs that take forever to track down because of type coercion. To battle this, we end up with code that is littered will conditionals for `null` or `undefined` values and type checks, making the core logic harder to read and refactor later. 

The **Maybe** encapsulates the type checking and guards against missing values for us. With **Maybe** in our toolbelt, we can keep our functions free of all the guardrails, outsource that work to the **Maybe** and keep our business logic free of all the clutter.

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.

Services and registering service providers are an inherent part of an Angular application. It is where you should define your application logic, they keep the state of the application and allow to share that among different components. 

That said, components can ask for instances of services by specifying them as parameters of their constructor functions which will then provided at runtime by Angular’s dependency injection mechanism. While services themselves are mostly just plain ES2015 classes, there are some interesting things to discover, especially when it comes to dependency injection. 

We can define services at various levels within our application, which allows us to control the scope and visibility of a given service. We can furthermore alias old service definitions to new, existing services which is handy for refactoring scenarios and we also have the possibility to define so-called factory functions for fully taking control of how a given service is being constructed. 

In this course we will take a closer look and walk step by step through all of these scenarios.

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.

Angular is particularly popular at large enterprises. Most of the time those line of business apps are very data driven and forms heavy. While Angular gives us two different approaches to implementing forms, neither of them is very satisfying, nor do they help keep the maintainability high especially in large enterprise apps. 

In this course we're going to learn about [ngx-formly](https://formly.dev/), a library that helps cope with some of the mentioned issues. With Formly you define the form structure once in your component code and the HTML will be taken care of by the library. This helps to reduce maintainability and moreover Formly has some nice reactive features built-in that help you reduce your form code even more.

The core of serverless architectures are auto-scaling systems and a pay-per-execution pricing. Two traits that allows developers to significantly reduce operational cost and complexity, by outsourcing infrastructure management to cloud providers and focus on building business logic.  

In this course we walk through the basics on how to create a serverless API. We start off creating a simple HTTP endpoint. Then we build the first two endpoints of a REST API for a simple Todo Application backend storing the data in DynamoDB. After watching this course you will be ready to get started building you first serverless backend.

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

Building your web app with a fully customized design is a daunting task. If you aren't a CSS expert, applying a design style to your markup can consume hours and hours as you try to tweak pixels, align elements, and bang your head on the desk in frustration.

Tailwind provides us with highly composable utility classes but leaves the design specification entirely up to the user to maintain that custom look and feel to your app.

In this course, you'll learn how to handle responsive breakpoints, how to trigger specific element states, how to handle specificity, how to keep your bundle file size in check, and how to seamlessly extend Tailwind with your own custom utility classes.

By the end of the course, you should have a firm understanding of how Tailwind works and be able to create your own tailor-made design system and utility class CSS toolkit for your next project!

Tailwind is a utility-first CSS framework for rapidly building custom user interfaces.

In this course we are going to work through properly setting up Enzyme with Jest to test rendered components. This includes the nitty gritty of making our testing environment work with various versions of React. After we get our environment setup ready, we’ll work through the different ways we can render a component within our test pages. With a rendered component we can now test component methods and properties to assert that they are what is intended.

This collection will cover the basics of how to interact with an HTML document with JavaScript. We will go over:

- What is the DOM?
- fetch elements from an HTML document
- add HTML nodes to a HTML document
- Respond to click events

Introduction to Client Side Web APIs

Frontend runtime optimization is heavily impacted by rendering.  Understanding the way the JS engine and the browser work is crucial for optimizing applications and understading how to avoid performance pitfalls.
This collection explains about the Critical Rendering Path, performance bottlenecks and practical solutions.

End-to-end testing assures you of a few things: that all the integrated pieces of an application properly function, all those pieces work together as expected, and your tests include and simulate real-user scenarios — something unit and integration tests just don't do.

This course introduces you to two great tools for E2E testing: 

* Puppeteer opens and runs applications in a Chromium browser and performs the actions it's given.
* Jest asserts that the integrated pieces work as expected and that add-on libraries like Faker and pixelmatch take our tests to the next level.

Over 9 lessons, we will create common application features and use Puppeteer and Jest to run different types of tests against them. You'll get practice using these tools to render content, mimic user activity, automate tests, and measure the overall performance of your application.

JSON Web Token (JWT) is a low overhead option for authentication that is easy to implement and scales with your application. There is no need to store session data as everything you need is stored in an encoded string sent in the JWT, significantly reducing database overhead for your servers.

In this course, we will build a simple authentication server that will act as a token issuer, and we will use those tokens to access resources on an API.  Starting from scratch, you will learn how easy token based authentication can be and will understand how to use them on your APIs as well as on the front end of your web applications.

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

This course explores the capabilities of TypeScript’s type system and shows how to use advanced static types in practice. For example, you’ll learn how to write safer code by using non-nullable types and being explicit about `null` and `undefined` in the type system. 

You’ll also see how the compiler analyzes control flow to determine the most specific type for a variable at any given location.

In addition to that, you’ll learn about the `readonly` modifier and the special `object` and `never` types. This course also inspects string enums, literal types, discriminated unions, and static types for the rest and spread operators. 

Finally, you’ll see how to type dynamic property access using the `keyof` operator and how to create new types by applying transformation functions to existing ones.

TypeScript is a typed superset of JavaScript that compiles to plain JavaScript.

***Note: Active maintenance for Recompose has been discontinued since the announcement for React hooks. Your existing code using Recompose will still work. Recompose is not compatible with RxJS version 6 and beyond. You can read more about the decision [here.](https://github.com/acdlite/recompose/issues/756#issuecomment-438674573)*** 


Loading data and handling events almost always introduces layers of complexity into React apps. Recompose and RxJS solve your async problems by using Streams to output components. This course walks you through combining the powers of React and RxJS to stream data into JSX with streaming patterns and pure React components.

In this collection, we build a minimal flashcard application using React, primarily focusing on function components and the hooks API. To make sure we can understand and maintain existing code, there are also a few lessons toward the end that use class components so you can get familiar with the syntax. We cover important React concepts, and sprinkle in libraries that are pretty standard in the ecosystem like @reach/router, Jest, and React testing library. We start with create-react-app so we can get right into it without worrying about configuring tooling. There's [a separate course for that here](https://egghead.io/courses/modern-javascript-tooling-with-react?af=5mx0ie)

Vue is known for being super easy to pick up and quickly build great applications using the built-in template bindings and directives. As your application grows in complexity, you'll need finer control of your components.

In this course, we’ll define where content of a component should land when you define the content inside of a parent component with Vue slots and manage that relationship with slot-scope. We’ll continue with dynamic and async Vue components as well as use JSX inside Vue for complete JavaScript control of your components. 

This course provides an overview of Advanced Vue.js Components with quick demonstrations on how to leverage Vue Component patterns.
