How do MSW and Axios handle errors differently?

What are the main differences in error handling between MSW and Axios?

MSW (Mock Service Worker) simulates API responses for testing, while Axios is a promise-based HTTP client. MSW allows you to mock errors easily, while Axios handles errors through catch blocks and response interceptors.

Can you give me an example of how to handle errors in Axios?

Sure! In Axios, you can use a try-catch block like this:

try {
  const response = await axios.get('/api/data');
} catch (error) {
  console.error('Error fetching data:', error);
}

How would I simulate an error response using MSW?

You can simulate an error response in MSW by defining a handler like this:

import { rest } from 'msw';

export const handlers = [
  rest.get('/api/data', (req, res, ctx) => {
    return res(ctx.status(500), ctx.json({ message: 'Internal Server Error' }));
  }),
];

Which one is better for error handling in a production app?

It depends on your use case. For production apps, Axios is better for real API calls, while MSW is great for testing and development.
