What are the best practices for using NgRx in Angular applications?

Some best practices include using feature modules, keeping state immutable, and leveraging selectors for state access.

Can you explain why immutability is important in NgRx?

Immutability helps to ensure that state changes are predictable and can be easily tracked, which is crucial for debugging.

What are selectors and how do they improve performance?

Selectors are pure functions that select a slice of state. They improve performance by memoizing results and reducing unnecessary re-renders.

How can I structure my NgRx store for a large application?

For large applications, consider using feature modules to encapsulate related state and actions, making the store more manageable.

Any tips for testing NgRx effects?

Use the NgRx testing utilities to create isolated tests for effects, ensuring they respond correctly to actions and handle side effects.
