Fixing Nginx 404 Errors for Laravel and React Apps: A Comprehensive Guide

If you're working with a Laravel application alongside multiple React apps hosted on an Nginx server, you might encounter frustrating 404 errors when refreshing certain routes. This common issue arises when your server configuration doesn't accurately handle routing for single-page applications (SPAs) like React. In this guide, we will break down the issue and present a robust solution to ensure smooth navigation within your applications.

Understanding the Problem

When you set up a setup with React and Laravel, your application might function perfectly initially. You can navigate to various routes without any issue. However, once you try refreshing a page or directly accessing a specific URL, you may receive a 404 Not Found error. This behavior typically occurs because Nginx does not correctly serve your application's entry point (index.html for React) when it encounters a request that doesn't correspond to a static file or route already defined in your server configuration.

Consider the following symptoms:

Accessing example.com/auth/login works initially but results in a 404 error upon refreshing.

You may have tried various configurations, only to end up frustrated as the problem persists.

Solution: Adjusting the Nginx Configuration

The good news is that there is a straightforward fix! Below is a step-by-step guide on how to modify your Nginx configuration to resolve the 404 errors:

Step 1: Update Your Nginx Configuration

Replace your existing Nginx configuration block with the updated configuration provided below. Pay close attention to how the route handling for React apps is constructed:

Benefits of This Configuration

SPAs Handling: This updated configuration ensures that any routes not found as static files in the defined directories route to the index.html file of your React applications, allowing the React router to handle the paths correctly.

Improved User Experience: Visitors can now refresh pages or use browser navigation without encountering errors, enhancing the application's usability.

Conclusion

By following these steps, you should be able to effectively eliminate 404 errors on refresh for your Laravel and React apps when served through Nginx. This method provides a reliable configuration for any developer encountering similar issues with their web applications.
