Resources for Web Developers in 2022

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 validation can be tough, but angular-formly makes it extremely simple with a single validation API that enables basic and advanced field validation. You can specify a string expression, function that returns true/false, or a function that returns a promise which is resolved/rejected.

Sass is the most mature, stable, and powerful professional grade CSS extension language in the world.

Tired of dealing with monolithic CSS files? Are requests for multiple CSS files hurting your performance? In this lesson we learn how to separate our styles with SCSS partials, and how SCSS imports compile to one file so there's only one request.

Organize SCSS into Multiple Files with Partials

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.

Applications are driven by state. Many things, like the user interface, should always be consistent with that state.
[MobX](https://mobxjs.github.io/mobx) is a general purpose FRP library that provides the means to derive, for example, a React based user interface automatically from the state and keep it synchronized.

The net result of this approach is that writing applications becomes really straight-forward and boilerplate free.

Python is a widely used dynamically typed programming language. It allows for many different programming paradigms including object-oriented, imperative, functional programming, and procedural styles.

Object oriented classes work much like classes in other languages. Learn how to create them and use them, learn the difference between class variables and instance variables, creating class methods, and learn how to create classes that inherit from other classes.

Use Python Classes

In this lesson, we see how we can apply styles globally with the "injectGlobal" helper method in styled-components. This method allows us to apply styles on the body element, which cannot be wrapped in a styled-component.

The Chrome Developer Tools (DevTools for short), are a set of web authoring and debugging tools built into Google Chrome.

Organize your log output by grouping your logs into collapsable hierarchies using console.group().

The Angular Material Layout API wraps the flexbox CSS features with an amazingly easy, powerful HTML markup API. The Layout API hides the complexities of the CSS, is intuitive to use, and eliminates the need for developers to become flexbox experts to implement modern page layouts. 

In this lesson we will learn how to use the Angular Material Container components and the Layout API to implement the layouts specified in design wireframe.

With Angular, most of the time you're specifying a templateUrl for your directives and states/routes. This means you need to make sure that you're loading in these templates into the $templateCache for your tests and production. Oh, and don't forget to update all your URLs whenever you move the files around! When you add in Webpack and the raw-loader, you don't need to do this anymore. Simply require the html file and your work is done!

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.

With ECMAscript 6 we get the luxury of default parameters for our functions.

Any extra information on the screen will easily distract the audience from the purpose of your lesson. Do your best to remove any extra notifications, UI, or other information that would take away from what you're teaching.

Remove Distractions

This lesson explains how you can build larger trees of react component and how they are managed efficiently by MobX. You will learn how to pass observable data structures around in props and how the Devtools can be used to analyze the performance of your UI.

This lesson explains how actions can be used to control and modify the state of your application. They help you to structure your code base and integrate well with the MobX React Devtools. Actions automatically create transactions, which group changes together.

Use MobX actions to change and guard state

The spread operator allows you to "explode" an array into its individual elements.

Using the ES6 spread operator

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

In this lesson we learn how to fetch new data whenever the refresh button is clicked. This lessons starts to give us a feeling of how is it to develop reactive applications in RxJS.

Any information you would want to put into an Intro or Outro belongs in the accompanying description, title, course page, etc. The lesson is only for showing the process. Talking about yourself, the lesson, or other lessons is a waste of time.

Avoid Intros and Outros

`Array.from()` lets you convert an "iterable" object (AKA an _array-like_ object) to an array. In this lesson, we go over grabbing DOM nodes and turing them into an array so that we can use methods like `Array.filter()` and `Array.forEach()` on them.

Converting an array-like object into an Array with Array.from()

We can write reusable styles with the SCSS @extend or @mixin directives. Which one is better? It depends. A better question is, how do they differ?
Extends:
change the source order, mixins don’t.
maintain relationships, mixins don’t.
share inherited traits, mixins don’t.
can extend multiple classes, mixins don’t.
can create multiple class declarations in the compiled CSS, mixins don’t.
can use the placeholder selector, mixins don’t.

Mixins:
can accept arguments, extends don’t.
can pass additional content, extends don’t.
repeat code when compiled, extends group class names together.
work well wIth media queries, extends have a limited interaction wIth media queries.

In this lesson we learn about writing reusable styles with the @extend directive and how it compares to the @mixin directive.


Reuse Styles with the SCSS @extend Directive

Themes convey meaning through color, tones, and contrasts. And the theme color palettes, alphas, and shadows deliver a consistent tone to your application and a unified feel for all Angular Material UI components. Theming allows developers to change the intention and meaning of the application by changing the colors and shadows. 

Accessibility is a huge - often overlooked - feature in modern web applications. Angular Material components all implement ARIA features whenever possible. And for usage scenarios where the ARIA attributes are not explicitly provided and cannot be inferred, then Angular Material will provide details console warnings alerting the developer.

Let’s use the Angular Material Theming service to change the background, primary, accent, and warning colors used within the entire application. These will be configured at startup using the $mdThemeProvider.  

Let’s also resolve the two ARIA warnings shown in console. These originate from icon buttons where the ARIA label cannot be inferred. So let’s add a static aria-label and a dynamic, interpolated aria-label to those buttons.

React requires some initial setup before we can get going with the app. In this lesson, we will use `create-react-app` to do this initial setup for us.

In this lesson we'll look at an overview of how Flux works, setup our application structure and tools, and create our first component.

The use of RxJS Subjects is common, but not without problems. In this lesson we will see how they can be usually safely replaced with plain Observables.
