React Router Browserrouter Leads To 404 Not Found Nginx Error When Going To Subpage Directly Without Through A Home Page Click

It can be quite frustrating when you're eager to navigate to a specific page on your React application, only to be greeted by a 404 Not Found error, especially if you are using React Router's BrowserRouter. This issue commonly occurs when attempting to access a subpage directly without navigating through the home page first. Fortunately, there is a simple solution to this problem that involves configuring your Nginx server to work seamlessly with React Router.

When you encounter the 404 Not Found error with React Router's BrowserRouter, it typically means that the server is not configured to handle browser history's client-side routing properly. Nginx, a popular web server, needs specific directives to ensure that all routes are correctly redirected to the index.html file, where React Router can take over and handle the routing internally.

To address this issue, you need to create or modify the Nginx configuration file for your React application. If you are using a standard Nginx setup, you can usually find the configuration file at /etc/nginx/sites-available/default. Open this file in your preferred text editor to make the necessary adjustments.

You will need to add or modify a location block within the server block of your Nginx configuration. Here's an example of how you can configure Nginx to work properly with React Router:

Nginx

server {
    listen 80;
    server_name yourdomain.com;

    root /path/to/your/react/app/build;
    index index.html;

    location / {
        try_files $uri $uri/ /index.html;
    }
}

In this configuration snippet, we set the root directive to point to the build folder of your React application. The index directive specifies that Nginx should look for index.html files by default. The crucial part is the location block, where we use the try_files directive to attempt to serve the requested URL directly. If that fails, Nginx will serve the index.html file, allowing React Router to handle the routing internally.

After making these changes to your Nginx configuration file, save the file and restart the Nginx service to apply the modifications. You can typically do this by running the following command:

Bash

sudo systemctl restart nginx

With these adjustments, your React application should now properly handle direct subpage access without encountering the 404 Not Found error. Users will be able to navigate seamlessly throughout your application, even when accessing subpages directly.

By configuring Nginx to work in harmony with React Router, you ensure that client-side routing functions correctly, providing a smooth and error-free user experience. Implementing these changes is a simple yet effective way to enhance the overall performance and functionality of your React application.
