Resources for Web Developers in 2022

NativeScript has the ability to write Objective C, Swift and Java apis directly from JavaScript and TypeScript. 

In this course, we will learn how to code directly against these native api’s with NativeScript for Angular. Many libraries are written and published in these languages. With NativeScript you are no longer limited to just JavaScript based libs, but have direct access to these api’s right from JavaScript/TypeScript. Let’s look at how to include these native libraries internally to your project as well as build public plugins to share with the community. 

We will cover some considerations with Objective C and Swift based libraries as well as Java/Android libraries. You can think of CocoaPod, Gradle, and Android Arsenal like npm for native libs. iOS libraries can be found via CocoaPods, Android libraries can be found via Gradle or Android Arsenal. 

Let’s also cover how to write custom view components based on native libs since there are considerations for both iOS and Android. Lastly we will learn how to best handle cases where a plugin/library only supports 1 platform.

This course teaches the ubiquitous abstractions for modeling pure functional programs. Functional languages have adopted these algebraic constructs across the board as a way to compose applications in a principled way. 

We can do the same in JavaScript. While the subject matter will move beyond the functional programming basics, no previous knowledge of functional programming is required. You'll start composing functionality before you know it.

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.

Vue.js has a first-class ecosystem to help construct Vue.js apps. This includes Nuxt.js which enables server-rendered applications and a page-based approach. 

This course will start with an empty app and walk through how to use Vue.js for building the app, Nuxt.js for organizing the app, and Vuex for managing state.

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.

If you have used RxJS Observables, it is likely you have seen the flatMap or switchMap operators. They are very powerful operators that can be used in various situations, while being common for dealing with HTTP requests. These operators may look mysterious at first, but turn out to be simple flattening operations on higher order Observables. 

In this course you will learn what is a higher order Observable, when does it occur in real applications, and how to handle them with operators like switchMap. Throughout this course we will see real applications of these operations.

Start following this course if you have some understanding of RxJS, but want to gain advanced skills in the art of using operators.

If you're new to RxJS, we highly recommend the [Introduction to Reactive Programming using RxJS](https://egghead.io/courses/introduction-to-reactive-programming) to begin with, and then [RxJS Beyond the Basics: Operators in Depth](https://egghead.io/courses/rxjs-beyond-the-basics-operators-in-depth) to understand operators.

If you're an absolute beginner to the concept of Observable and async streams, we highly recommend starting with [Jafar Husain's excellent introduction](https://egghead.io/courses/mastering-asynchronous-programming-the-end-of-the-loop).

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

It’s really fun to work with graphics when building apps and websites, but how do you get started? HTML5 has a technology called **Canvas** that lets us draw graphics to our screens. We can do everything from making basic shapes to creating complex interactive games and animations!

 In this course, we will learn the basics of using **Canvas**. We’ll start by learning how to create a canvas on an HTML page. Next we will learn how to draw and style with fills and strokes. Finally, we will add interactivity to canvas elements.

HTML 5 is the structure of our web pages. It is the markup that represents the DOM (document object model).

npm is like a giant library of code building blocks. There are tons of these “blocks”, aka “packages” that we can compose together to build cool things. We can use packages by other developers, but we can also write and publish our own. 

In this course we will learn how to create, publish, and update our own packages. We will create a JavaScript utility module to filter out sensitive words from a string, including tests and development file watching. We will then cover publishing and updating our package. This same approach can be used to create and publish other types of packages too like components (React, Angular, Web Components etc.) and command line interfaces.

npm is the package manager for JavaScript. Find, share, and reuse packages of code from hundreds of thousands of developers — and assemble them in powerful new ways.

Ember is a javascript framework that provides a rich set of tools for building modern web applications. Unlike many frameworks, Ember comes with opinions and a way of doing things so you aren't left with a ton of decisions to make about problems that have already been solved very well. Ember was designed from the start to deliver a productive and comfortable experience for you, the developer.

In this course you will learn what you need to know to get started building your own Ember we applications. From the absolute essentials like creating a new project with the Ember-CLI tools, templating, routing, and reusable components.

In this course, we are going to learn about the CSS Grid Layout. The Grid Layout is a feature in CSS available in modern browsers.

CSS Grid layout is a two-dimensional layout method that gives you control over items in rows as well as columns. In this course we will look at multiple ways to divide the page into major regions with control of the size, position, and layer.

We’ll discuss all the features CSS Grid has to offer us, and how we can apply these features to real world layout-based obstacles. We’ll start with placing items on a grid by using grid-column and grid-row and progress to more complex topics such as nesting grids within grids.

Cascading Style Sheets bring order and beauty to our applications.

A large part of a software developer’s time is spent searching the internet for answers to a never-ending stream of questions. Often, the answers we find are on blogs written by people who’ve been there, and found a solution. Isn’t it time you paid it forward?

Gatsby.js is a static site generator for React with a plugin ecosystem that makes it super easy to publish.

In this course, you’ll build a Gatsby site that transforms Markdown documents from your local filesystem into HTML. From there, you’ll use GraphQL to query posts for displaying on an index page, link between posts, and group posts by tags. After your site has been compiled, you’ll see how to deploy it via Github Pages.

Have you ever wished for access to conditionals or iteration when writing styles? How cool would it be to use functions to write styles? SCSS has that and more! SCSS is a superset of CSS. Any valid CSS is SCSS, they even have the same syntax. SCSS borrows features from other languages to write smarter, reusable and more readable styles. This course will focus on how to use SCSS’s more useful features, compare them against each other and assess when their usage is appropriate.

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

This is the video companion to the [egghead.io Instructor Guide](https://howtoegghead.com/instructor/).

Screencasting is hard! There are virtually infinite ways to produce one. For an egghead.io lesson we expect several key aspects to be met. We want to make sure that our lessons have depth and clarity. Clarity is important and starts with the technical aspects of recording your screen and voice. Once we have achieved this objective level of clarity, we dip into the stylistic aspects of recording a lesson. The style is subjective, and the goal of an egghead.io lesson is not to have an army of uniform drone producing flavorless video content for the masses.

Our mission is to make you a badass screencaster. We want to push you to another level. We've found that a small set of standard practices will create an awesome experience for the student, and eliminate frustration as we teach by providing a repeatable pattern for success. It’s not complicated. In fact, it is simple, but it isn’t easy.


This course will show you how to produce an egghead.io lesson. We strive for consistency in style, and these lessons will demonstrate the core elements that create our brand screencasts. Let’s learn how together.

Looking at snippets of CSS is a great way to learn how to use it, but some details can fall through the cracks. This course demonstrates the process of styling an application from start to finish.

We will take a basic un-styled todo-list application written in React and use CSS to get the application to look like how we want. The first steps will be to apply static styles to the app based on a mock up, then we will incrementally add user interactivity as well as make the app responsive.

Style an Application from Start to Finish

In this course we will show you how to wield the power behind the elusive window function. Which five movies were the highest grossing each year? Who are the highest performers in each department relative to their peers? These questions ask us to partition records into subgroups and answer questions about those groups -- that’s the power of a window function. 

Many programmers will reach for their favorite scripting language to solve problems like these, but window functions allow you to answer them with the speed and efficiency of the Postgres query planner.

Plus, with the power to further slice and dice this derivative information, there’s no limit to the questions you can answer with raw SQL.

In this course, we will learn how to use the core layouts for NativeScript apps. We will start with the basic principles of NativeScript layouts using XML. This course will use the app templates provided from the NativeScript framework and installed using [the NativeScript CLI](https://egghead.io/lessons/angular-1-x-set-up-a-native-app-project-with-the-nativescript-cli).

We will cover the following layouts: `StackLayout`, `WrapLayout`, `GridLayout`, `DockLayout`, `AbsoluteLayout` and `FlexboxLayout`. Understanding the concepts and usage of UI layouts in NativeScript is key for a great app.

In this course we will learn how to use the ES2017 async and await keywords to write asynchronous code that is more readable and easier to follow than equivalent code based on long promise chains or deeply nested callbacks. 

The await operator takes a promise and then pauses the function execution until that promise is settled which allows for an async function to read like sequential synchronous code.

This course will start by showing us how to convert a function doing a simple HTTP request into an async function using async/await. By the end of the course we will be able to loop over asynchronous data sources using a `for-await-of` async generator function.

Asynchronous JavaScript with async/await

CMD+F in your text editor can only get you so far! In this course, we will learn to use grep and find, two powerful command-line utilities, to search through and explore our codebase. Learn to search specific files and folders, using regular expressions to look for -- or ignore! -- particular phrases. We'll cover how to search recursively, get more context on your results, and some simple tricks to make your searches faster and more targeted.


Once you're familiar with grep and find, you'll be able to quickly answer questions such as: Do I use this function anywhere other than my tests? Where does this file get imported? Whether you're working on a new feature, reading a codebase for the first time, or refactoring existing code, grep and find can help you work faster and more effectively.

***Note: RxJS imports have changed since the publication of this course. The concepts being taught on RxJS are still applicable.*** 

RxJS Subjects are a source of confusion for many people using RxJS. For many, the Subject is the obvious and only answer to every problem. Subjects are incredibly useful and necessary, but the key is to know when to use them for solving specific problems that you encounter.

In this course, we are going deep into RxJS Subjects and multicasting operators. You'll gain a solid understanding of when, where, and how to use these powerful tools.

If you are new to RxJS, or want a refresher please check out this course **[Introduction to Reactive Programming](https://egghead.io/courses/introduction-to-reactive-programming)**.

RxJS Subjects and Multicasting Operators

With the variety of choice we have in building modern web applications using JavaScript, it can make it difficult to understand where to even begin. We live in a wondrous era, where every problem we have seems to have a corresponding javascript module on npm that we can install with just a few keystrokes. It’s easy!


Often, “easy” can mean the opposite of simple. Easy is “quick to do”, where simple is “quick to understand”.


KISS.


In this course you will learn how to build production quality React applications. We will strive to keep things as simple as possible, with minimal dependencies. Instead of typing `npm install`, we will build our own simple solutions first, to get a solid understanding of the problems that we are solving through libraries. We will build our tools in a functional style, and write appropriate unit tests to verify that they work as expected.


If you are brand new to React, you’ll want to read the documentation and watch our [free React Fundamentals course](https://egghead.io/courses/react-fundamentals).

Build Your First Production Quality React App

In this course we will introduce the topic of using npm scripts as a build tool. We will start simple and then continue to build a small website as we introduce new topics. By the end of the course, you'll know how to get started and what tools and techniques are needed for you to create your own set of build scripts.

How to Use npm Scripts as Your Build Tool

It’s amazing how much you can accomplish with a basic knowledge of SQL. In this course we’ll learn how to store lots of information (many millions of things!) and answer nearly any question we might have about that information (on the order of milliseconds!) 

We’ll learn enough to make you say you “know SQL” -- table creation, inserts, selects, updates, deletes, aggregations, indexes, joins, and constraints. Along the way we’ll model real world problems so that you can see just how powerful SQL will make you!

Get Started With PostgreSQL

As a developer, you'll often make use of APIs that have you pass in a callback function. For example, adding event listeners or using various other DOM or Node APIs.

What's less common is writing your own code that makes use of callbacks. Many developers know *what* a callback is, but not the why or how of implementing them in their projects.

A callback is a function that you pass to another function, so that the function that you pass it to controls the invocation of that function.

To help keep things straight, John Lindquist calls the innermost callback the Listener, and the function it gets passed into the Broadcaster.

Think of it as one function *broadcasting* values to another function that is *listening* for them. 

These Broadcaster-Listener callback relationships can be composed to solve problems in the realm of timing, buffering, and caching.

This pattern of composing callbacks is the foundation of RxJS and other libraries that handle complex async scenarios.

In this course, John Lindquist guides you from a blank JavaScript file all the way through creating a library of reusable functions not unlike those found in RxJS. The difference is you'll be writing from scratch.

You'll learn techniques for solving Callback Hell with composition, implementing debouncing, and building a word game among several other examples.

Using callbacks in code is a major pattern in JavaScript, and learning to work with them effectively will take your problem-solving skills to the next level.
