What are the best practices for using Axios in Next.js?

When using Axios in Next.js, it's important to handle API calls efficiently. Here are some best practices:

1. Use Axios instances for default configurations.
2. Handle errors gracefully with try-catch blocks.
3. Utilize Next.js's data fetching methods like getStaticProps and getServerSideProps for server-side data fetching.
4. Keep your API calls organized in a separate service file.

How can I create an Axios instance?

You can create an Axios instance by importing Axios and using the axios.create method. Here's an example:

import axios from 'axios';

const api = axios.create({
  baseURL: 'https://api.example.com',
  timeout: 1000,
  headers: {'X-Custom-Header': 'foobar'}
});

What should I do if an API call fails?

If an API call fails, you should handle the error in your catch block. You can log the error, show a user-friendly message, or retry the request. Here's an example:

try {
  const response = await api.get('/data');
} catch (error) {
  console.error('API call failed:', error);
  // Show a user-friendly message
}
