3 min read 07-09-2024

If you're a web developer, chances are you've heard of GitHub Pages—a service that allows you to host static websites directly from your GitHub repository. But what if you want to take your website a step further with a modern framework like React? In this article, we’ll walk through the steps to deploy a React application on GitHub Pages, making your project accessible to the world with just a few clicks!

What is React?

React is a powerful JavaScript library used for building user interfaces, particularly single-page applications. It allows developers to create reusable components, making it easier to manage complex UIs. Think of React as a set of building blocks—you can mix and match them to create the perfect structure for your application.

Why Use GitHub Pages?

GitHub Pages is a free hosting solution that allows developers to publish websites quickly and easily. It's perfect for hosting portfolio sites, project documentation, or even React applications without needing to worry about server management.

Steps to Deploy a React App on GitHub Pages

Here’s a step-by-step guide to help you deploy your React application on GitHub Pages:

Step 1: Create Your React App

If you haven’t already created a React app, you can do so using Create React App. Open your terminal and run the following command:

npx create-react-app my-react-app
cd my-react-app

Step 2: Install GitHub Pages Package

To deploy to GitHub Pages easily, you’ll need to install the gh-pages package. Run the following command in your terminal:

npm install gh-pages --save-dev

Step 3: Configure Your Package.json

In your package.json file, add the following lines:

Add a homepage field, which tells GitHub Pages where to find your app:

"homepage": "https://<USERNAME>.github.io/<REPOSITORY_NAME>"

Replace <USERNAME> with your GitHub username and <REPOSITORY_NAME> with the name of your repository.

Add the following scripts under the existing scripts:

"predeploy": "npm run build",
"deploy": "gh-pages -d build"

Your scripts section should now look something like this:

"scripts": {
  "start": "react-scripts start",
  "build": "react-scripts build",
  "test": "react-scripts test",
  "eject": "react-scripts eject",
  "predeploy": "npm run build",
  "deploy": "gh-pages -d build"
}

Step 4: Create a GitHub Repository

Go to GitHub and create a new repository.
Initialize the repository with a README file (optional).
Clone the repository to your local machine.

Step 5: Push Your Code

Add your React app's code to the cloned repository:

git init
git add .
git commit -m "Initial commit"
git remote add origin https://github.com/<USERNAME>/<REPOSITORY_NAME>.git
git push -u origin master

Step 6: Deploy to GitHub Pages

Run the following command in your terminal:

npm run deploy

This command will build your app and deploy it to the gh-pages branch of your repository.

Step 7: Access Your Live App

Once the deployment process is complete, navigate to:

https://<USERNAME>.github.io/<REPOSITORY_NAME>

You should see your React app live!

Troubleshooting Common Issues

404 Errors: If you encounter a 404 error after deployment, check your React Router configuration, as GitHub Pages doesn’t handle client-side routing by default. You may need to use a 404.html redirect as a workaround.
Blank Page: If your page is blank, ensure you’ve specified the homepage in your package.json correctly.

Conclusion

Deploying a React app on GitHub Pages is a straightforward process that allows you to showcase your work to a wider audience. By following the steps outlined in this article, you can transform your local project into a live application in just a few minutes.
