How to Retrieve a Token from Redux Store for Axios Instance in React

When developing a React application that requires secure API interactions, handling authentication tokens efficiently is key. If you're using Redux to manage the global state of your application, you might find yourself needing to retrieve a token stored in the Redux store to use it in your Axios instance. This can be a bit tricky, especially since the typical use of useSelector is confined to functional components. In this guide, we'll discuss how to properly set up your Axios instance and retrieve the token from Redux using Axios interceptors. Let's dive in.

Understanding the Problem

You have an Axios instance configured to handle API requests, but you need to include an authorization token stored in your Redux store to ensure those requests are authenticated. The challenge lies in accessing Redux state outside of a functional component, where useSelector isn’t available. This is a common scenario among developers, but fortunately, there are efficient solutions.

Solution: Using Axios Interceptors

One effective approach to solve this issue involves using Axios interceptors. Interceptors allow you to run your code or modify the request before it is sent to the server. This is perfect for adding the authentication token to your requests.

Step-by-Step Guide to Set Up Axios Interceptors

Create Your Axios Instance:
First, you will want to create your base Axios client instance. This is where you define your configurations such as the base URL and default headers.

Set Up the Interceptor:
Now, you can add a request interceptor to your Axios instance. This interceptor will fetch the token from your Redux store and attach it to the headers of each request made using this instance.

Use the Axios Instance:
Now whenever you make a request using axiosClient, the interceptor ensures that the token is included in the request headers.

Why Use Interceptors?

Decouples Authentication Logic: Using interceptors allows you to keep your authentication logic separate from your API calls.

Consistency: Every request made with your Axios instance will consistently include the authorization token.

Simplification: Reduces the need to modify each individual request.

Conclusion

Using an Axios interceptor is a powerful solution for accessing a token from the Redux store and integrating it into your API requests. It enhances security and maintains clean, manageable code by decoupling the concerns of authentication from your API requests. By following the steps outlined above, you can secure your React app with minimal hassle.
