Understanding the Problem: nginx + React Router Routing Issues

If you're running a web application using React and utilizing the react-router for routing, you might face issues with properly displaying routes beyond the homepage. This is especially common when your application is served through an nginx reverse proxy. A typical problem is when you navigate to a route such as domain.com/some-route, and you end up seeing a 404 error page instead of your intended component.

In this guide, we'll explore a simple yet effective solution to this common issue, ensuring that your application's routes are handled correctly by nginx while keeping the desired URL structure.

Key Insight into the Issue

The fundamental issue arises from how the server handles requests to different routes. When you navigate directly to domain.com/some-route, the nginx server is expecting a static file to respond to that path. Since React applications are single-page applications (SPAs), all routing is managed client-side, which means that nginx doesn't find a corresponding file on the server, leading to a 404 error.

Solution Breakdown

Understanding Your Setup

Before diving into the solution, ensure that you understand your current environment:

Two Instances of nginx: It's crucial to note whether you're running multiple instances of nginx, such as one on your server and another within a Docker container. This can lead to confusion when configuring your routing.

Steps to Resolve Routing Issues

Identify Your Configuration:
Ensure you’re working with the correct nginx configuration. If you have multiple instances, confirm which one serves your React application.

Update nginx Configuration:
Modify your nginx configuration to include a rule that will redirect requests properly. Here’s a simple configuration example:

proxy_pass: This line forwards the request to your backend.

try_files $uri /index.html: This directive tells nginx to try and find the requested URI, and if it doesn't exist (like in cases of client-side routes in an SPA), to serve the index.html file instead.

Deploy Changes:
After updating the configuration, you will need to build your application and then deploy it within the correct Docker container if applicable.

Test Your Application:

Now, navigate to both domain.com and domain.com/some-route to verify that the application displays as expected.

If successfully configured, both routes should render the correct components without a 404 error.

Final Thoughts

Once the proper configuration is applied, you’ll find that navigation across your React application works seamlessly, even when directly accessing nested routes. The takeaway here is understanding how to effectively configure nginx to work with SPAs, particularly when using routing libraries like react-router.

By ensuring that all your routes fall back to serving your index.html file when requested URIs aren’t found, you can maintain a clean URL while allowing your React application to handle the routing internally.



Now you should have both the knowledge and the refreshed configuration strategy to tackle your routing issues with nginx and React Router. Happy coding!
