What are the best practices for using Axios in Vue?

When using Axios in Vue, it's important to keep your API calls organized. Here are some best practices:

1. Create a separate service file for API calls.
2. Use interceptors for handling requests and responses.
3. Manage error handling effectively.
4. Use async/await for cleaner code.

Can you explain how to set up interceptors?

Sure! You can set up interceptors in your Axios instance. Here's a basic example:

import axios from 'axios';

const instance = axios.create({
  baseURL: 'https://api.example.com',
});

instance.interceptors.request.use(config => {
  // Do something before request is sent
  return config;
}, error => {
  // Handle the error
  return Promise.reject(error);
});

instance.interceptors.response.use(response => {
  // Any status code that lie within the range of 2xx cause this function to trigger
  return response;
}, error => {
  // Handle the error
  return Promise.reject(error);
});

This allows you to modify requests or responses globally.

What about error handling?

For error handling, you can use a centralized approach. Create a function to handle errors and call it in your catch blocks. For example:

function handleError(error) {
  if (error.response) {
    // The request was made and the server responded with a status code
    console.error('Error:', error.response.data);
  } else if (error.request) {
    // The request was made but no response was received
    console.error('No response received:', error.request);
  } else {
    // Something happened in setting up the request that triggered an Error
    console.error('Error:', error.message);
  }
}

Then use it in your API calls.
