Learn Flux-architecture, Nginx and Ngrx-store

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.

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.

Reactive State Management in Angular with ngrx

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

Angular has many built-in features for working closely with RxJS to help you build entirely reactive applications. This course will teach you how to use Angular with RxJS. We will learn how to use the ngrx/store library to manage state in a clean, reactive "Redux style."

This course assumes you've got a working knowledge of Angular and reactive programming with RxJS. If you don't, you might want to watch the following courses to get you up to speed!

Build Redux Style Applications with Angular, RxJS, and ngrx/store

As a React application grows, so does the needs for organization and patterns. How do components communicate? How do we manage state across the application? How is data shared between components? 

These are the questions that Flux was built to answer.

In this series, we will explore React Flux, using ES6 (ES2015), babel, and webpack to manage our developer workflow.

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.

React: Flux Architecture (ES6)

Reducers are also often used for changing a single property inside of other reducers. This lesson shows how a type can enter the people reducer, but then the people reducer can use a different type to call the clock reducer and get a value back.

Use a Reducer to Change an Object's Property Inside an Array

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

Flux Architecture: Overview and Project Setup

In this lesson we'll create a very simple application dispatcher utilizing the open source flux dispatcher from Facebook.

Flux Architecture: Application Dispatcher

In this lesson we'll create our Flux application's store which will manage the state of our application.

Flux Architecture: Application Store

In this lesson we'll create our initial components using the architecture we've built so far.

Flux Architecture: Components/Views

In this lesson we'll shift the responsibility of managing the state of our application over to a higher-order component rather than having each component managing it's own state.

Flux Architecture: Higher-Order Components

In this lesson we'll organize our components by feature.

Flux Architecture: Project Organization

Using our established architecture we'll make short work of a few remaining tasks to meet our application requirements.

Flux Architecture: Component Wrap Up

In this lesson we'll simplify future development by reducing the logic contained in our application's store.

Flux Architecture: Dumb Stores

This lesson summarizes everything the course has covered and how Angular 2, RxJS, and ngrx/store work together to achive a reactive application.

Review of Angular 2, RxJS, and Reducers from ngrx/store

The scan operator in RxJS is the main key to managing values and states in your stream. Scan behaves just as a reduce function would, but scan is able to collect values from streams over time. This lesson covers using startWith to set the initial accumulator value then using scan to update the value of the clock from the clicks and interval.

Manage State in RxJS with StartWith and Scan

In this lesson we'll build our actions which will be sent to our dispatcher.

Flux Architecture: Application Actions

While you have multiple streams flowing into your scan operator, you'll need to map each stream to the specific values you need to update your state the way that you want. This lesson covers using the map operator to determine what the click and interval should do when the state is updated.

Map Streams to Values to Affect State

Angular templates use a special Async pipe to be able to render out Observables. This lesson covers the syntax used to create an Observable in Angular and then to render it out in the template.

Render an Observable with the Async Pipe

ngrx/store is a library that simplifies common RxJS patterns for managing state and gives you an easy api to use it within your Angular application. This lesson shows how to convert a common startWith and scan stream into an ngrx Store and reducer.

Use ngrx/store and Reducers for Angular Application State

Angular allows you to pass values from inputs simply by referencing them in the template and passing them into your Subject.next() call. This lesson shows you how to make a number input and pass the value so you can configure how much you want the clock to change.

Pass Template Input Values to Reducers

The components inside of your container components can easily accept Observables. You simply define your custom @Input then use the Async pipe when you pass the Observable in. This lesson walks you through the process of passing an Observable into a Component.

Pass Observables into Components with Async Pipe

Reducers can easily be used inside one another to update related state. This lesson shows how you can use the clock reducer inside of the people reducer to create the time for each new person.
