Axios network error

by

When making API requests using the Axios library, you might encounter a “network error” if there is a problem with the network connection or if the server is not responding.

The network error can occur due to various reasons, such as:

  • No internet connection
  • Server is down or unreachable
  • CORS (Cross-Origin Resource Sharing) issues
  • Firewalls or security settings blocking the request
  • Timeout or latency issues

Here is an example of how to handle network errors with Axios:

// Import Axios library
import axios from 'axios';

// Make a request to an API endpoint
axios.get('https://example.com/api/endpoint')
  .then(response => {
    // Handle successful response
    console.log(response.data);
  })
  .catch(error => {
    // Handle network error
    if (error.response) {
      // Server responded with a status code outside the range of 2xx
      console.log(error.response.data);
      console.log(error.response.status);
      console.log(error.response.headers);
    } else if (error.request) {
      // No response received from the server
      console.log(error.request);
    } else {
      // Other errors occurred during the request
      console.log('Error', error.message);
    }
  });

In the above example, we use the Axios library to make a GET request to an API endpoint. The .then() block handles the successful response, and the .catch() block handles any network errors.

Within the .catch() block, we can check the error.response property to determine if a response was received from the server. If it exists, it means that the server responded with a non-successful status code (outside the range of 2xx), and we can access the response data, status code, and headers.

If the error.response property is not available, it means that no response was received from the server. We can access the error.request property to debug and investigate the issue further.

In any other cases, such as if the request couldn’t be sent or other errors occurred, we can access the error.message property to get the error message.

By handling network errors appropriately, you can provide useful feedback to the user and handle different scenarios gracefully within your application.
