How can I effectively mock APIs in Next.js for debugging?

You can use libraries like MSW (Mock Service Worker) or Mirage JS to mock APIs in your Next.js application. These tools allow you to intercept network requests and return mock responses, which is great for testing and debugging.

Can you give me an example of how to set up MSW in a Next.js project?

Sure! First, install MSW using npm or yarn. Then, create a mocks directory and set up your handlers. Finally, initialize MSW in your pages/_app.js file to start intercepting requests.

What are some common issues I might face while mocking APIs?

Common issues include not properly intercepting requests, mismatched response formats, and forgetting to start the mock service. Always check your console for errors!

How can I test my components with mocked APIs?

You can use testing libraries like Jest along with React Testing Library. Render your components within a test, and use MSW to provide the necessary mock responses.
