Understanding the Problem

Consider the following code snippet where this issue might arise:

The code attempts to redirect the user to the login page when a 401 error occurs. However, when using BrowserRouter from react-router-dom, you may encounter the error log:

This happens because BrowserRouter does not expose a push method directly, making a more structured approach necessary for navigating away from routes based on external sources like Axios interceptors.

The Solution: Creating Custom History

To handle routing outside React components effectively, you can create a custom history object. This allows you to utilize routing functions such as push, replace, etc., in non-component JavaScript files, like your Axios interceptor.

Step-by-Step Instructions

1. Install history package

If you haven't already, you must install the history package in your React project. This package provides utilities needed to manage session history in your application.

2. Create a History Instance

Import the necessary tools from react-router-dom and the history package to create a custom history object.

3. Update Your Application's Router

Now that you have a custom history instance, you can use it within your app's Router component. Replace your existing Router component with the newly created custom history.

4. Use the Custom History in Axios Interceptor

You can now modify your Axios interceptors to use the custom history object for navigation. This will allow you to use the push method seamlessly.
