Learn how to effectively use _redirects for deploying your React single-page applications on Netlify, ensuring smooth routing and server configuration.

Introduction

Deploying a React single-page application (SPA) on Netlify offers a seamless and efficient hosting solution. However, managing client-side routing can present challenges, particularly when users navigate directly to specific routes or refresh the page. This is where the _redirects file becomes essential. In this guide, we’ll explore how to use _redirects for Netlify React routing, ensuring your SPA functions flawlessly in a production environment.

Understanding React Routing on Netlify

React Router is a popular library for managing navigation within a React application. It enables developers to create dynamic and responsive user interfaces by handling routing on the client side. However, Netlify, being a static site host, serves only static files by default. This discrepancy can lead to issues where navigating to routes other than the root (/) results in 404 errors.

The Challenge with SPA Routing

When a user navigates to a route like netlify.app/about, the browser makes a direct request to the server for the /about page. Since Netlify serves static files, it looks for an /about file or directory, doesn’t find it, and returns a 404 error. While React Router handles routing seamlessly in a local development environment, this server-side limitation poses a problem in production.

The Solution: Using the _redirects File

Netlify provides a powerful feature to handle such routing issues: the _redirects file. By configuring this file, you can instruct Netlify to redirect all requests to the index.html file, allowing React Router to manage the routing on the client side.

Step-by-Step Guide to Creating and Using _redirects

Create a _redirects File

In the public directory of your React project, create a file named _redirects (no file extension).

Add Redirect Rules

Open the _redirects file and add the following line:

/* /index.html 200

This rule tells Netlify to redirect all routes (/*) to index.html with a 200 HTTP status code, ensuring that React Router handles the routing.

Deploy to Netlify

Commit and push your changes to your repository. Netlify will automatically detect the _redirects file during deployment and apply the redirect rules.

Verify the Deployment

After deployment, navigate to different routes in your application. The routes should now work correctly without resulting in 404 errors.

Common Issues and Troubleshooting

404 Errors on Direct Route Access

Even after setting up the _redirects file, some users might still encounter 404 errors when accessing routes directly. Ensure that:

The _redirects file is correctly placed in the public directory.
The syntax in the _redirects file matches the required format.
There are no typos or extra spaces in the redirect rules.

Form Submission Causing URL Issues

If your application uses forms that trigger route changes, ensure that they use proper link components instead of forms with GET requests. For example, replace:

<form method="get" action="/about">
  <button>About</button>
</form>

with:

<a href="/about" className="button">About</a>

This change prevents unintended URL query parameters and ensures smoother navigation.

Best Practices for React Deployment on Netlify

Optimize Build Settings: Use the appropriate build command (npm run build) and publish directory (build) in Netlify settings.
Leverage Environment Variables: Securely manage API keys and other sensitive information using Netlify’s environment variables feature.
Enable HTTPS: Ensure your site uses HTTPS for enhanced security and SEO benefits.
Monitor Deployments: Utilize Netlify’s deployment logs to monitor and troubleshoot any issues that arise during the build process.
