What are ngrx effects and how do they work?

NgRx Effects are a way to handle side effects in Angular applications using the NgRx library. They allow you to isolate side effects from your components and manage them in a more organized way.

Can you give me an example of how to implement an ngrx effect?

Sure! Here's a simple example: you can create an effect that listens for a specific action, like 'LOAD_DATA', and then makes an HTTP request to fetch data. When the data is received, it can dispatch another action, like 'LOAD_DATA_SUCCESS'.

What are some common use cases for ngrx effects?

Common use cases include handling API calls, managing complex asynchronous operations, and integrating with third-party libraries.

How do I test ngrx effects?

You can test ngrx effects using the TestBed from Angular and the NgRx testing utilities. You would typically mock the actions and services to ensure your effects behave as expected.
