Are you tearing your hair out because your React app’s routing isn’t working on your deployed AWS Elastic Beanstalk instance? Well, you’re not alone! This is a common issue many developers face, and it’s often due to a simple misunderstanding of how routing works in a production environment.
What’s Going On?
When you’re developing your React app locally, everything seems to work fine. You navigate between routes, and your app behaves as expected. But, when you deploy your app to an AWS Elastic Beanstalk instance, suddenly your routing stops working. You click on a link, and instead of rendering the desired component, you’re greeted with a 404 error or a blank page.
The Reason Behind the Problem
The issue lies in how React Router handles client-side routing versus server-side routing. In a development environment, React Router uses the browser’s history API to manipulate the URL and render the corresponding component. However, when you deploy your app to a server, the server doesn’t know how to handle these client-side routes.
Solving the Problem
Fear not, dear developer! The solution is relatively straightforward. You need to configure your Elastic Beanstalk instance to handle client-side routing correctly. Here’s a step-by-step guide to get you back on track:
Step 1: Update Your `package.json` File
In your `package.json` file, add the following script:
"scripts": {
"build": "react-scripts build",
"start": "serve -s build"
}
This script tells your app to use the `serve` package to serve your built app in production mode. The `-s` flag tells `serve` to serve the app in single-page application (SPA) mode, which is essential for client-side routing to work.
Step 2: Configure Your Elastic Beanstalk Environment
In your Elastic Beanstalk environment, navigate to Configuration > Container options. Scroll down to the Static files section and add the following configuration:
Mime type |
Extension |
Action |
text/html |
/* |
index.html |
This configuration tells Elastic Beanstalk to serve `index.html` as the default document for all requests.
Step 3: Update Your `index.html` File
In your `index.html` file, add the following line of code:
<base href="/" />
This line sets the base URL for your app, which is essential for client-side routing to work.
Step 4: Update Your React Router Configuration
In your React Router configuration, make sure you’re using the `BrowserRouter` component and not the `HashRouter` component. The `BrowserRouter` component uses the HTML5 history API, which is necessary for client-side routing to work in a production environment.
import { BrowserRouter } from 'react-router-dom';
ReactDOM.render(
<React.StrictMode>
<BrowserRouter>
<App />
</BrowserRouter>
</React.StrictMode>,
document.getElementById('root')
);
Step 5: Deploy Your App
Finally, deploy your app to your Elastic Beanstalk instance. Once the deployment is complete, your routing should be working as expected.
Troubleshooting Common Issues
If you’re still experiencing issues with your routing, here are some common issues to check:
Issue 1: 404 Errors
If you’re getting 404 errors, make sure you’ve configured your Elastic Beanstalk environment correctly. Double-check that you’ve added the `Static files` configuration and updated your `index.html` file.
Issue 2: Blank Pages
If you’re getting blank pages, make sure you’re using the `BrowserRouter` component and not the `HashRouter` component. Also, ensure that your `index.html` file is being served correctly.
Issue 3: Routing Not Working with Subdomains
If you’re using subdomains with your app, make sure you’ve updated your `index.html` file to include the subdomain in the base URL.
Conclusion
There you have it, folks! With these steps, you should be able to get your React app’s routing working on your deployed AWS Elastic Beanstalk instance. Remember to update your `package.json` file, configure your Elastic Beanstalk environment, update your `index.html` file, update your React Router configuration, and deploy your app.
If you’re still experiencing issues, don’t hesitate to reach out to the React and AWS communities for further assistance. Happy coding!

Frequently Asked Question
Getting stuck with routing issues on your React app deployed on AWS Elastic Beanstalk? Don’t worry, we’ve got you covered! Here are some frequently asked questions to help you navigate through the problem:
Why is my React app routing not working on AWS Elastic Beanstalk?
This is likely because Elastic Beanstalk is not configured to handle client-side routing. By default, Elastic Beanstalk treats URLs as server-side requests, which can cause routing issues with React apps. To fix this, you need to configure your Elastic Beanstalk environment to serve your React app as a single-page application (SPA).
How do I configure Elastic Beanstalk to serve my React app as a single-page application (SPA)?
You can do this by creating a custom configuration file (.ebextensions) in your project root. This file should contain the necessary settings to configure your Elastic Beanstalk environment to serve your React app as a SPA. For example, you can add the following lines to your .ebextensions file: option_settings:. This tells Elastic Beanstalk to serve your React app from the /public directory.
"aws:elasticbeanstalk:container:nodejs:staticfiles":
"/public: /public"
What if I have a React Router setup with multiple routes?
In that case, you’ll need to configure your Elastic Beanstalk environment to handle client-side routing for all routes. You can do this by adding a catch-all route to your .ebextensions file. For example: option_settings:. This tells Elastic Beanstalk to serve all routes starting with /public/* from the /public directory. This will allow your React Router to handle client-side routing for all routes.
"aws:elasticbeanstalk:container:nodejs:staticfiles":
"/public/*: /public/*"
Do I need to make any changes to my React app code?
No, you don’t need to make any changes to your React app code. The configurations mentioned above are done on the Elastic Beanstalk side, and they will work with your existing React app code. However, if you’re using a custom routing setup, you might need to adjust your routing configuration to work with the Elastic Beanstalk environment.
How do I test my React app routing on Elastic Beanstalk?
Once you’ve configured your Elastic Beanstalk environment, you can test your React app routing by deploying your app to Elastic Beanstalk and accessing the different routes in your app. You can use the Elastic Beanstalk environment URL to access your app. For example, if your environment URL is http://myapp-env.us-west-2.elasticbeanstalk.com/, you can access your app routes by appending the route paths to the environment URL.
