Deploying a React.js Application to Cloudflare Pages: A Step-by-Step Guide

3 min readNov 27, 2023

React.js has become a popular choice for building dynamic and interactive web applications. Once you’ve developed your React.js application, the next step is deploying it to make it accessible to users worldwide. Cloudflare Pages is a powerful platform that simplifies the deployment process and provides a fast and secure hosting solution. In this article, we’ll guide you through the steps to deploy your React.js application to Cloudflare Pages.

Prerequisites:

Before we start, make sure you have the following prerequisites:

Cloudflare Account: You need to have a Cloudflare account. If you don’t have one, you can sign up for free at Cloudflare.
GitHub Repository: Your React.js application should be hosted on a GitHub repository. If it’s not already there, you can create a new repository and push your code to it.

Steps to Deploy:

1. Create a Cloudflare Pages Account:

Go to the Cloudflare Pages website.
Log in with your Cloudflare account credentials.
Follow the on-screen instructions to set up your Cloudflare Pages account.

2. Connect GitHub Repository:

After creating an account, click on the “Create a project” button.
Connect your GitHub account and select the repository containing your React.js application.

3. Configure Build Settings:

Cloudflare Pages will automatically detect the type of application based on the repository. However, you might need to configure the build settings for a React.js application.
Specify the build command (e.g., npm run build) and the output directory (e.g., build).

4. Build and Deploy:

Cloudflare Pages integrates with GitHub Actions to automate the build and deployment process.
Trigger the first build by committing and pushing a change to your GitHub repository.
Monitor the build progress in the Cloudflare Pages dashboard.

5. Configure Custom Domain:

Once the build is successful, navigate to the “Settings” tab in your Cloudflare Pages project.
Under the “Custom Domains” section, add your domain or use the default Cloudflare Pages domain.

6. Set Up DNS:

To complete the deployment, you need to update your DNS settings.
Cloudflare Pages will provide you with specific DNS records. Copy these records and add them to your domain registrar’s DNS settings.

7. Wait for DNS Propagation:

DNS changes may take some time to propagate globally. Be patient and wait for the changes to take effect.

8. Access Your Deployed React.js Application:

Once the DNS propagation is complete, you can access your React.js application using your custom domain or the default Cloudflare Pages domain.

Congratulations! You have successfully deployed your React.js application to Cloudflare Pages. Cloudflare’s global CDN ensures that your application is delivered quickly to users worldwide, providing a fast and secure user experience.

Additional Tips:

Environment Variables: If your React.js application relies on environment variables, you can configure them in the Cloudflare Pages dashboard under the “Environment Variables” section.
Custom Redirects and Headers: Cloudflare Pages allows you to set up custom redirects and headers for your application. You can configure these in the “Page Rules” section of the Cloudflare dashboard.
SSL/TLS Configuration: Cloudflare provides free SSL/TLS certificates, ensuring that your deployed React.js application is served over HTTPS. Verify the SSL/TLS settings in the “SSL/TLS” tab of your Cloudflare dashboard.

By following these steps, you’ve not only deployed your React.js application but also leveraged Cloudflare’s robust infrastructure for fast and secure content delivery. Enjoy the benefits of a scalable and reliable hosting solution for your dynamic web applications.
