How to Use Axios with Authentication Tokens in 2025?

In 2025, handling API requests securely and efficiently is more crucial than ever. Axios, a popular HTTP client for JavaScript, continues to be a reliable choice for making requests to APIs. One of the most common use cases is sending requests with authentication tokens. This article will guide you through using Axios with authentication tokens effectively.

Why Use Axios?

Axios simplifies the process of making HTTP requests and integrates well with JavaScript applications. It supports promise-based calls and can be used in both node.js and browser environments. With its ability to intercept requests and handle responses, Axios is perfect for managing authentication tokens.

Integrating Axios with Authentication Tokens

To utilize Axios for requests requiring authentication tokens, follow these steps:

1. Install Axios: Ensure Axios is installed in your project. You can do this by running:

1

   npm install axios

1. Set Default Headers: To include your authentication token in Axios requests, set the default header for authorization. This ensures that every request contains the token.

   axios.get('https://api.example.com/secure-endpoint')
     .then(response => {
       console.log('Data:', response.data);
     })
     .catch(error => {
       console.error('Error:', error);
     });

Security Considerations

• Secure Storage: Store your authentication tokens securely. Consider using environment variables or secure storage solutions available in your platform.

• Token Rotation: Implement token rotation if your authentication service supports it, to enhance security.

• Error Handling: Always handle errors, especially around token expiration or invalid tokens.
