Learn Angular, Redux and Svelte

JavaScript community has been shaken recently by a release of Svelte 3 and for a good reason - it's a completely different approach than React or Vue. To quote the docs:

"[Svelte](https://svelte.dev/) is a radical new approach to building user interfaces. Whereas traditional frameworks like React and Vue do the bulk of their work in the browser, Svelte shifts that work into a compile step that happens when you build your app."

**The best part?** If you have 26 spare minutes you can learn the basics of Svelte 3 and start building your own apps with it!

Enjoy!



The magical disappearing UI framework

 - The web's JavaScript bloat crisis, solved. Svelte turns your templates into tiny, framework-less vanilla JavaScript.
 - Simple and familiar. Build apps out of composable, easy-to-write blocks using languages you already know.
 - Super fast, rock solid. Compile-time static analysis ensures the browser does no more work than it needs to.

Angular is a robust, powerful framework for building applications at scale, but it can be really intimidating to beginners! This collection by [JavaScript teacher Sam Julien](http://www.samjulien.com/) is here to help you learn Angular in bite-sized chunks. 

*Note from Sam: these lessons are loosely related but are not meant to necessarily be followed in order from start to finish. I've provided embedded code and links to GitHub where applicable, though, so you can always have access to the finished code for the lesson.*

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 Basics

Angular elements are one of the major innovations in Angular 6+. Elements allow us to develop Angular components like we always have through Angular’s powerful API, and then compile them into browser-native custom elements. With custom elements, we can define new HTML elements in a framework-agnostic way that adheres to web standards. We can also extend the HTML by defining a tag whose content is created and controlled by JavaScript code.

In this course, we’ll look at how to leverage Angular elements within our Angular apps to make them even more dynamic — a use case that’s commonly required in CMS-like environments. Going a step further, we’ll also see how we can compile our Angular elements into a standalone script file, which you can integrate into any other web context to pass data and register events on your custom elements.

Thanks for joining us!

Build Performant and Progressive Angular Applications

At a high level Redux is just a dispatching system, sitting atop a finite state machine, driving our application state. It just so happens that the State ADT is good at modeling a finite state machine. It allows us to represent our stateful transactions in discrete, easily composed transactions. We can create complicated stateful transitions by composing many simple transitions into one state transaction. By using the State ADT, we should be able to model all of our application state transitions and provide a single reducer function to Redux that integrates with our state machine model.

We’ll put this theory to the test by building a Memory type game called “Anger The Bunny”.  We start of by defining our state transitions using the State ADT, starting with simple, discrete transactions and using them to create the complex transitions typical of any game. Then once we have a majority of our game logic implemented, we will integrate those with Redux.

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.

Redux and the State ADT

As your Angular application grows, it becomes more difficult to manage application state.

NgRx can help with that!

In this course, we will learn how to convert an Angular application from using stateful services into using NgRx.

We will accomplish this by adding a new feature, including building a reducer and actions. We'll also touch on using selectors to query our state, managing collections with NgRx entity, async operations, and hiding implementation details with the facade pattern.

Reactive State Management in Angular with ngrx

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.

Reduce Redux Boilerplate with Redux-Actions

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.

Advanced Angular Component Patterns

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.

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.

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).

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 Service Injection with the Dependency Injector (DI)

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.

In this course we will explore integral Angular Material components. We will start with components related to navigation, layout, and structure. We will then move through the utility, input, and datatable components, demonstrating how each can be used to suit your project’s needs. Finally we will touch on theming your application to create a custom look and feel that fits within the Material Design guidelines.

By the end of the course you will be comfortable leveraging the Angular Material library to create an outstanding interface and user experience!

Client-server communication is at the heart of any modern web application. In this course we will take a look at how to communicate with your backend API in Angular, specifically with the new Http module(`@angular/common/http`) introduced and used in Angular  `4.3.1` and later.

We will learn how to configure the `HttpClientModule`, how to fetch and send data, customize HTTP headers that are being sent and how to properly handle error responses.

We will also take a look at some more advanced use cases such as listening to progress events and intercepting HTTP calls. Finally we will also learn how to isolate and mock HTTP calls in automated unit tests.

When we build forms, we know there’s a good chance that the data we want to collect may change. Dynamic Forms in Angular give us the ability to define the underlying object model before binding the form to the template. This lets our forms programmatically adjust to the underlying model so we don’t have to update each form manually as our data will eventually change.

In this course Google Developer Expert-led we will use Angular’s Reactive Forms and learn about the basics for dynamically rendering `FormControls`. We will also explore how more advanced input controls such as select boxes and radio button lists can be dynamically bound to our template. 

If you’re coming from AngularJS (v1.x) you may also be familiar with dynamic forms in the context of `Formly`, a library for automating dynamic forms. We will also quickly touch on `ng-formly`, which is the Angular (2+) equivalent.

Create Dynamic Forms in Angular

Dynamic data gives us the opportunity to build dynamic components. Dynamic components are reusable and make building large-scale applications so much easier. In this course, Juri Stumpflohner will take us through the specific use case of of creating a tabbed component which allows us to dynamically define new tabs.

On our journey of implementing this component we will learn about how we can dynamically instantiate components, leveraging the `ComponentFactoryResolver` and `ViewContainerRef`.

Furthermore we will explore how to define view templates, how to pass them to our dynamically instantiated components as well as how to pass data into those templates. All of this will be powered by `ngTemplateOutlet` and `ngTemplateOutletContext`.

***Note: RxJS imports have changed since the publication of this course. Operators now must be passed into `.pipe` to be applied to an observable.***

In this course we will begin with nothing more than an empty directory & a text editor. Through small, focussed lessons we’ll learn how to setup a React project that uses Redux for state management and redux-observable for asynchronous actions. We’ll see how ‘epics’ are registered and how they each receive a ‘stream’ of actions from the store. 

With an understanding of how things work, we’ll move onto solving common problems such as Ajax cancellation, creating sequences of async actions, enabling code reuse through higher-order Observables and much more.

Managing state in modern web applications is hard. As applications grows in complexity, keeping track of state changes and mapping those changes back to your UI becomes increasingly difficult.

One way data flow makes managing state more approachable and lightens the cognitive load required to follow the flow of data through your application. Using Redux takes this idea to the next level and moves the state and the state changes and centralizes them in a global store, managed with pure reducer functions.

In this course you will learn how to build a production quality React application using Redux. We will build up from using redux by itself, so we can understand the core API and how that interacts with a React application, then we’ll move on to introduce `react-redux` to abstract away some of the underlying details and clean up our code. We’ll use middleware and a mocked API server to understand how asynchronous code fits into the Redux model and we’ll even deploy our finished work so we can see it running live in the cloud. 

If you are brand new to React, you’ll want to read the documentation and watch our free [React Fundamentals](https://egghead.io/courses/start-using-react-to-build-web-applications) course and our [Build Your First Production Quality React App](https://egghead.io/courses/build-your-first-production-quality-react-app) course.

Developers usually have a love-hate relationship with CSS and styling user interfaces. But it is a fundamental part of creating nice-looking, adorable and successful user interfaces. In this course we will take a deep dive into the various possibilities Angular offers for styling components. We learn about the different APIs, how they allow us to conditionally apply one or multiple styles in the form of style attributes and CSS classes. We also explore the concept of style encapsulation and how it helps prevent our styles from leaking into other components.

Understand How to Style Angular Components

Building native mobile applications has traditionally been a completely foreign work flow than web development. Recently frameworks, such as Ionic and React Native, have been come out to create a similar web development workflow in a native environment. 

Ionic 2 builds on top of Angular to offer a complete framework for building mobile apps using HTML, CSS, and Javascript that target native mobile and the browser. We’ll work with the RandomUser API to create an employee directory that will let us view user details, update that information, and pass the data back and forth with Ionic 2 routing.

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.
