This course is designed to teach you how to manage states in Angular using the powerful NgRx library.

You’ll learn the fundamentals of state management and how it can be implemented in an Angular application using NgRx. Next, you’ll learn how to use the NgRx store, actions, reducers, and selectors to manage the application states and handle complex data. You’ll also learn how to handle side effects and asynchronous operations in an Angular application.

Throughout the course, you’ll gain hands-on experience in implementing state management using interactive projects. You’ll learn best practices and design patterns for state management in Angular and how to structure the state of an application using NgRx. Additionally, you’ll learn how to write unit test cases for NgRx features.

By the end of the course, you’ll be able to implement and debug states in an Angular application. You’ll be able to create more scalable, maintainable, and testable Angular applications that can handle complex states and data.

Mastering State Management with Angular and NgRx

# Redux principles

Redux is based on the following three principles:

- A Redux app has a single source of truth called the store.

- The store is read-only and can only be changed by dispatching actions.

- Changes are made using pure functions called reducers.

# Redux architecture

- We should keep our entire app's state in a single JavaScript object called store.

- Our app's components/views subscribe to the store for the required data.

- When the state needs to get updated through user interactions, the component/view dispatches an action. The action contains information about the new data.

- The action forwards the information to a reducer function. The reducer uses that information to modify the state.

- Since the component/view has already been subscribed to the store, it gets updated automatically with the new data.

Let's briefly recap what we have learned in this chapter.
