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

# Working with lazy-loaded modules

When an Angular application loads, all of its modules load as well. This is known as eager loading. This is the default behavior of all the Angular modules. However, if we specify a module as lazy-loaded, it will only be loaded when the user requests it.

During compilation, each lazy-loaded module gets bundled independently. It helps keep the initial bundle sizes smaller, which in turn helps decrease load times.

# The common mistake developers make

The main goal of creating lazy-loaded modules is to entirely decouple the functionality of that module from the initially bundled code. Developers often import interfaces from the lazy-loaded modules into the eagerly loaded modules. As a result, the lazy-loaded module mistakenly gets compiled into the initially bundled code.

Let's briefly review what we learned in this chapter.
