What are some practical examples of using NgRx in Angular applications?

NgRx is a state management library for Angular. Here are a few practical examples: 1. Managing user authentication state. 2. Handling complex forms with reactive state. 3. Caching API responses for better performance.

Can you elaborate on how to manage user authentication state with NgRx?

Sure! You can create an authentication feature state that includes properties like 'isLoggedIn' and 'userDetails'. Use actions to log in, log out, and store user data, and reducers to update the state accordingly.

What about handling complex forms?

For complex forms, you can use NgRx to manage the form state. Create actions for form input changes and validation results, and use selectors to retrieve the current form state in your components.

Are there any best practices for using NgRx?

Yes, some best practices include keeping your state immutable, using feature modules for better organization, and leveraging effects for side effects like API calls.
