Solving the React Router Nested Routes Issue with Correct HTTP Requests

When building applications with React, especially those that use react-router, it's common to encounter issues related to nested routes and API calls. One particular problem that developers often face is how to ensure that HTTP requests function correctly within nested routes. In this post, we’ll discuss a common scenario involving react-router and provide a clear solution to ensure your API requests are structured correctly.

The Problem: Incorrectly Formed HTTP Requests

Let’s take a look at a specific issue that has arisen in a React application. The developer set up routes to display a list of products based on a selected category. Here’s how they defined the route in the App.js file:

And when they navigate to the category, they use:

However, when attempting to make an HTTP request inside the ProductLists component, something unexpected happens. Instead of sending the request to the intended endpoint, the request gets malformed, and the URL looks like this:

The issue here is that the "category" path is being inserted at the start of the request URL. This can be frustrating and can halt development progress.

The Solution: Adding baseURL to Axios Requests

Fortunately, the solution to this problem is quite straightforward. You need to specify a baseURL for your Axios requests. This tells Axios where to start building the request URL from and avoids issues with relative paths. Here's what the corrected Axios request looks like:

Key Changes Explained:

baseURL: By setting this to '/', you inform Axios that the requests should start from the root of your server rather than being relative to the current route. This prevents "category" from appearing at the beginning of the URL.

Maintaining Headers: We also ensure that the headers are set up correctly for the JSON content type.

Conclusion

By correctly setting the baseURL in your Axios requests, you can resolve issues related to incorrect URL formation in react-router nested routes. This simple fix can save you time and frustration while developing your React applications. Remember, when facing similar issues, checking the base URL often leads to a quick solution.

We hope this post helped clarify how to address the problem of malformed HTTP requests in nested routes. If you're ever in doubt, don’t hesitate to reconsider how your API requests are structured. Happy coding!
