Resources for Web Developers in 2022

The tools available for unit testing have come a long way. While testing may never be “easy”, the available tools have certainly moved testing closer to the simple end of the spectrum. Full end to end testing hasn’t quite kept the same pace and as a result many applications are testing manually and often by users in production. Cypress provides a testing environment that makes end-to-end testing fast and reliable with a simple API that makes creating automated unit tests for your web applications a no-brainer.


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

A collection of lessons about generators in JavaScript to help developers understand how useful they can be in many common scenarios.

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.

Generators in JavaScript

Eleventy, or 11ty,  is a simple yet very powerful static site generator. It does not require any config to get started.

This what it will take you to get an 11ty project running.

```
npm install -g @11ty/eleventy
echo '# Page header' > README.md
eleventy
```

After watching this collection you will be able to:

* Bootstrap a simple 11ty website
* Use 11ty layouts
* Chaining multiple 11ty layouts
* Use 11ty Collections
* Create pages from data

...and much more

Eleventy was created to be a JavaScript alternative to Jekyll. It’s zero-config by default but has flexible configuration options. Eleventy works with your project’s existing directory structure.

Eleventy uses independent template engines. We don’t want to hold your content hostage. If you decide to use something else later, having your content decoupled in this way will make migration easier.

GraphQL is a fan favorite for good reason. It lets a client make specific, complex, and/or aggregate queries for data, and it’s user-friendly to boot.

If you’ve been meaning to learn GraphQL and start harnessing its powers, this is a great place to start.

This course is for GraphQL newbies with a basic understanding of React. It focuses on the client-side implementation of GraphQL usage using the Apollo client.

We’ll start with a guide on how to add the Apollo client to an existing project, then move on using the Query and Mutation components to fetch and manipulate data using a GraphQL API.

***Note: RxJS imports have changed since the publication of this course, these changes to RxJS have been reflected in the code examples underneath each lesson. The concepts being taught on RxJS are still applicable.***

Vue.js is an amazing framework that can easily update and reflect user input using templates and data-binding. But there are many scenarios where complex asynchronous behaviors (like loading data, handling "pending" states, timeouts, etc) are solved much easier by leveraging the streaming capabilities of RxJS. This course covers how to setup and use the features of "vue-rx" to enable streams within your templates and easily solve complex scenarios.

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.

Redux is a powerful way to manage application state, but that power can come with a lot of code. A single update can sometimes require changes across many files and the code required to define action creators and to handle those actions in your reducer can start to get pretty repetitive.

The redux-actions library offers a small but powerful API to help cut down on some of the boilerplate that is typical of an application that uses Redux to handle state management.

Redux is a predictable state container for JavaScript apps.
It helps you write applications that behave consistently, run in different environments (client, server, and native), and are easy to test.

Reduce Redux Boilerplate with Redux-Actions

GitHub Actions are a powerful workflow tool that allows you to write and use custom code to execute workflows. It's like a serverless CI/CD platform built directly into GitHub. We have access to GitHub's registries, our own repos, multiple platforms (Mac, Windows, Linux), runtimes (VMs and Containers), and languages (JS, Rust, Go, etc) to perform any action we want. We can trigger workflows using GitHub's own events, our custom events, or even scheduled events like a cronjob.

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

Working with forms can be laborious, but redux-form takes out the tedium and replaces it with an enjoyable way to create beautifully crafted forms. You get the benefit of integrating form state with an existing Redux application, plus the ability to track the state of your form with precision in Redux DevTools, without writing lots of boilerplate code.

In this course, we will use the redux-form package to create a form whose state is easy and enjoyable to manage. Over 46 minutes and 14 lessons, we will:
* find out how redux-form ties into a React/Redux application
* learn how to use both synchronous and asynchronous validation
* use real-world examples and effective ways of presenting relevant information to the user

Learn to create precise, reusable form components, and enjoy yourself in the process.

Many languages work on a compilation story to WebAssembly, but Rust is already ready for primetime. Why?


- Rust is a stable language and great replacement for C and C++. 
- Due to the reference and borrowing concept, Rust doesn’t need a Garbage Collector and can be used for a production-ready WebAssembly project. 
- The Rust/Wasm team has built some sophisticated tooling for straightforward interoperability between Rust and JavaScript.

This course gives you the tools to compile to WebAssembly with Rust. Over 11 lessons, we’ll set up a project and explore various paths of communication and interoperability between Rust and JavaScript.

Rust is a systems programming language that runs blazingly fast, prevents segfaults, and guarantees thread safety.

Components are all about encapsulating decisions. The perfect component makes good decisions for you without making you think about it. Of course, no one knows what decisions you’re going to want. To make components reusable, we set reasonable defaults, then allow you to override them when you don’t like the decisions made for you.

This course covers three broad categories of decisions that can be encapsulated in a component: state, view, and logic. You’ll learn to move an Angular component from completely static to very configurable using a variety of techniques.

The course takes some of the most popular components in web development and applies them to Angular. You’ll learn to write components that are opinionated about their core purpose, but allow parent components to overwrite secondary concerns when pain points require a more complex pattern.

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.

Advanced Angular Component Patterns



Humans were never meant to repeat joyless tasks in a precise manner, over and over and over. Computers are meant precisely for these types of tasks.

Bash is a ubiquitous technology in web development that gives you the immense power of automating repetitive tasks you find yourself performing throughout the day.

The topics we cover will give you confidence in creating build scripts that run on continuous integration servers or quickly testing and debugging an API with `curl`. We’ll go over:  - Interacting with the file system - Creating, moving, copying, and deleting files and folders - Finding files and text patterns in files - Creating and running scripts - Language syntax like variables and conditionals.

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.

While this course is for IBM Domino Developers who are looking to utilize Node.js alongside their applications, or Javascript developers looking to integrate with a Domino server. There are quite a few tips and tricks you can learn for integrating Node.js as a proxy server for any REST API you might want to communicate with your JavaScript Application.

We cover how you can continue to use cookies provided by IBM Domino for user authentication and authorization while accessing a Node.js / Express based application, including modifying the standard login form to expose authentication errors.  

We show how to store user level information inside a JWT giving the option to store functional levels of access safely.  This stateless token can then be decoded server side to list what user roles a user has and therefore can restrict functionality without having to refer back to Domino each time.

The course will demonstrate Create, Read, Update and Delete methods using the Domino Data Services all via the NodeJS application but still maintaining Domino security.

And finally, we show how you can reuse Domino generated HTML inside a handlebars template by scraping and manipulating the HTML.

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

How do inherent prototypes work?

You might not think this question applies to you, especially if you come from a classical background. But if you use objects, functions, or arrays, you're probably already using prototypes, and can benefit from learning the logic behind them. 

This course explores the mechanics of inheritance in JavaScript by showing how prototypes work as chained references to other objects. Learn to take full advantage of prototype shortcuts to make your work simpler and faster…and debug them if you hit a snag. 

We’ll explore: 

- how to manipulate prototypes to work like traditional classes
- how polymorphism and factory functions can be used within JavaScript
- how the `class`, `new`, and `this` keyword work and how to use them
- using the `instanceof`, `Object.create`, and `Object.getPrototypeOf` functions to explain why objects have the properties that they do

Develop the knowledge needed to use inheritance for faster, better, bug-free code.

In this course we will learn some of the basics of getting data into and out of Neo4J, as well as touch on some of the libraries and tooling available in the Neo4J community ecosystem, which we will leverage to quickly create and use a full-featured GraphQL API.

We will start by learning how to run and interact with Neo4J locally. Then we will develop a graph model in which to store the data that we pull from SWAPI via REST. We will then create an Apollo GraphQL API driven by a few simple schemas which fit into this model. We will then write some simple code to crawl SWAPI and insert the data into Neo4J through our GraphQL API. Once there is data in the store, we will learn about some of the features in `neo4j-graphql-js` that make connecting and accessing our graph Nodes easier.

Neo4j delivers the lightning-fast read and write performance you need. Neo4j combines native graph storage, scalable architecture optimized for speed, and ACID compliance to ensure predictability of relationship-based queries.

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.

Offline-First Progressive Web Apps (PWA) in Vue.js

In this course we will create an Angular application that will serve as a public website. Normally there are quite a few trade-offs by using a Single Page Application for a public website. For instance, they are hard to index by search engines and if you link to them on social media you get a generic preview. Also, the initial rendering can take a while (especially on mobile devices) as the browser has to pull in all the JavaScript in order to render a working app.

By adding and configuring Angular Universal we add Server Side Rendering capabilities to our application. This helps prevent the issues mentioned above by pre-rendering the application on the server and serving this out to the user when she requests the app. Once the JavaScript has been loaded the app will seamlessly switch over to a ‘normal’ web application.

For good measures and to modernize our application we will add and configure a Service Worker that will allow for a native-like experience in the browser (splash screen, desktop icon, fast load, cached data, etc).
