How to deploy React apps to GitHub Pages

GitHub Pages offers a simple and free way to host static websites, making it an excellent option for deploying React applications. This guide will walk you through the process of deploying a Create React App project to GitHub Pages, customizing your domain, and automating deployments with GitHub Actions.

Quickstart: Deploy your React App in three steps

If you already have a Create React App project and GitHub repository set up, you can deploy your app with these three quick steps:

1. Install the gh-pages package

npm install gh-pages --save-dev

2. Update your package.json

{
  "homepage": "https://yourusername.github.io/your-repo-name",
  "scripts": {
    "predeploy": "npm run build",
    "deploy": "gh-pages -d build",
    // other scripts...
  }
}

3. Deploy your app

npm run deploy

That’s it! Your app will be available at https://yourusername.github.io/your-repo-name.

Note: This guide focuses on Create React App projects. If you’re using Vite, Next.js, or another framework, the deployment process will be different. For Vite projects, check the official Vite deployment guide. For Next.js, refer to the Next.js deployment documentation.

For a complete walkthrough, troubleshooting common issues, and advanced deployment options, continue reading below.

To follow along, you should have:

• A GitHub account, or set one up
• Familiarity with Git commands
• Node.js 18+ installed, or you can install it here
• A project created with Create React App (CRA)

What is GitHub Pages?

GitHub Pages is a service from GitHub that enables you to add HTML, JavaScript, and CSS files to a repository and create a hosted static website.

The website can be hosted on GitHub’s github.io domain (e.g., https://username.github.io/repositoryname) or your custom domain. A React app can be similarly hosted on GitHub Pages.

How to deploy a React application to GitHub Pages from scratch

To deploy your React application to GitHub Pages from scratch, follow these steps:

1. Set up your React application
2. Create a GitHub repository for your project
3. Push your React app to your GitHub repository
4. Install and configure gh-pages
5. Deploy your application

For a working example of this entire process, check out the react-gh-pages-example repository, which provides the source code you will see later in this article.

Setting up the React application

Let’s get started by creating a new React application. For this tutorial, we’ll be using create-react-app with React 18 and Node 20+.

Open the terminal on your computer and navigate to your preferred directory:

cd desktop 

Create a React application using create-react-app:

npx create-react-app "your-project-name"

In just a few minutes, create-react-app will have finished setting up a new React application! Now, let’s navigate into the newly created React app project directory:

cd "your-project-name"

Creating a GitHub repository

The next step is to create a GitHub repository to store our project’s files and revisions. In your GitHub account, click the + icon in the top right and follow the prompts to set up a new repository:

After your repository has been successfully created, you should see a page with commands to push your existing repository:

Now, initialize Git in your project:

git init

Add your files, commit, and push to your GitHub repository:

git add .
git commit -m "first commit"
git branch -M main
git remote add origin https://github.com/yourusername/your-repo-name.git
git push -u origin main

Installing and configuring gh-pages

Next, we’ll install the gh-pages package (version 6.0.0 or later) in our project. This package allows us to publish build files into a gh-pages branch on GitHub, where they can then be hosted:

npm install gh-pages --save-dev

Now, let’s configure the package.json file to point our GitHub repository to the location where our React app will be deployed.

Add a homepage property that follows this structure: http://{github-username}.github.io/{repo-name}. For example:

{
  "name": "your-project-name",
  "version": "0.1.0",
  "homepage": "https://yourusername.github.io/your-repo-name",
  // ...
}

Now, add the predeploy and deploy scripts to the scripts section of your package.json:

{
  // ...
  "scripts": {
    // ...
    "predeploy": "npm run build",
    "deploy": "gh-pages -d build"
  },
  // ...
}

The predeploy script will build your React app, and the deploy script will publish the build folder to the gh-pages branch of your GitHub repository.

Deploying your application

Now that everything is set up, commit your changes and push them to your GitHub repository:

git add .
git commit -m "setup gh-pages"
git push

Finally, deploy your React application by running:

npm run deploy

This command will create a bundled version of your React application and push it to a gh-pages branch in your remote repository on GitHub.

To view your deployed React application, navigate to the Settings tab in your GitHub repository, click on the Pages menu, and you should see a link to the deployed app:

Common issues and troubleshooting

When deploying React apps to GitHub Pages, you might encounter some common issues. Here’s how to diagnose and fix them:

Blank page after deployment

If you see a blank page instead of your app:

1. Check your homepage URL — Ensure your homepage property in package.json exactly matches your GitHub Pages URL format (https://username.github.io/repo-name)

2. Check browser console for errors — Open the developer tools in your browser to see if there are any errors related to failed resource loading

3. Verify file paths — If you’re using relative paths for assets, they might break in production. Update them to use the PUBLIC_URL environment variable:

<img src={`${process.env.PUBLIC_URL}/logo.png} alt="Logo" />

404 errors on page refresh or direct URL access

If your app works on the homepage but shows a 404 when refreshing or accessing direct routes:

1. Use HashRouter instead of BrowserRouter — GitHub Pages doesn’t support the browser history API. Update your index.js file to use HashRouter:

import { HashRouter as Router } from "react-router-dom";root.render();

This will change your URLs from /about to /#/about but will resolve the 404 issues.

2. Create a 404.html redirect — Alternatively, you can add a custom 404.html file that redirects to your index.html with the original URL parameters preserved.

Missing assets

If images, fonts, or other assets aren’t loading:

1. Use relative paths — Ensure all assets are referenced with paths relative to your homepage
2. Update import paths — For imported assets, make sure the paths are correct
3. Check case sensitivity — GitHub Pages is hosted on Linux servers, which are case-sensitive, unlike Windows. Ensure your asset paths match the exact case of the filenames

Repository configuration issues

Common repository configuration issues include:

1. GitHub Pages source not set correctly — Go to Settings > Pages and ensure the source is set to “Deploy from a branch” with “gh-pages” selected as the branch
2. Missing permissions — If using GitHub Actions, ensure the workflow has the correct permissions to deploy to GitHub Pages
3. Branch protection rules — If you have branch protection rules, make sure they don’t prevent deployment to the gh-pages branch

Build errors

If your deployment fails during the build process:

1. Check your Node.js version — Ensure you’re using a compatible Node.js version (14+)
2. Dependency issues — Try deleting your node_modules folder and package-lock.json file, then run npm install again
3. Check for environment variables — If your app requires environment variables, make sure they’re properly set up in your CI/CD process or GitHub repository secrets.

Adding a custom domain

We can deploy our React app to GitHub’s domain for free, but GitHub Pages also supports custom subdomains and apex domains. Here are examples showing what each type of subdomain looks like:

Supported custom domain	Example
www subdomain	www.logdeploy.com
Custom subdomain	app.logdeploy.com
Apex domain	logdeploy.com

Right now, if we navigate to https://yourusername.github.io/your-repo-name/, we’ll see our recently published website. But we could also use a custom subdomain or an apex domain instead. Here are the steps to set those up:

Deploying to a GitHub custom subdomain

1. Purchase a domain name from a domain service provider of your choosing (e.g., Namecheap or GoDaddy)
2. Connect the custom domain to GitHub Pages. To do so, click on the Pages menu on the Settings tab. Next, scroll down to the Custom domain field and enter the newly purchased domain name. This will automatically create a commit with a CNAME file at the root of your repository:

1. Ensure the CNAME record on your domain service provider points to the GitHub URL of the deployed website (in this case, yourusername.github.io). To do so, navigate to the DNS management page of the domain service provider and add a CNAME record that points to username.github.io where username is your GitHub username

Deploying to a GitHub apex domain

To deploy to an apex domain, follow the first two steps above for deploying to a custom subdomain, but substitute the third step with the following:

1. Navigate to the DNS management page of the domain service provider and add an ALIAS record or ANAME record that points your apex domain to your GitHub Pages IP addresses, as shown:

• • 185.199.108.153
  • 185.199.109.153
  • 185.199.110.153
  • 185.199.111.153

How to deploy a React app with routing to GitHub Pages

If you’ve previously deployed a React app that uses React Router for routing to Netlify, you’re aware that you need to configure redirects for your URLs. Without redirects, users will get a 404 error when they try to navigate to different parts of your application.

Netlify makes it simple to configure redirects and rewrite rules for your URLs. All you need to do is create a file called _redirects (without any extensions) in the app’s public folder.

Then, simply add the following rewrite rule within the file:

/*    /index.html  200

No matter what URL the browser requests, this rewrite rule will deliver the index.html file instead of returning a 404.

If we want to handle page routing when we deploy to GitHub Pages, we’ll need to do something similar. Let’s configure routing for our previously deployed project.

First, we need to install a router. Start by installing React Router in the project directory, like so:

npm install react-router-dom

Then, follow the next steps.

1. Connect a HashRouter to the application to enable client-side routing:import React from ‘react’;

import ReactDOM from 'react-dom/client';
import './index.css';
import App from './App';
import reportWebVitals from './reportWebVitals';
import { HashRouter as Router } from "react-router-dom";
const root = ReactDOM.createRoot(document.getElementById('root'));
root.render();
// If you want to start measuring performance in your app, pass a function
// to log results (for example, reportWebVitals(console.log))
// or send to an analytics endpoint. Learn more: https://bit.ly/CRA-vitals
reportWebVitals();

Our index.js file should look like the above code block. Because GitHub Pages does not support browser history, we’re employing a HashRouter. Our existing path does not assist GitHub Pages in determining where to direct the user (because it is a frontend route).

To solve this issue, we must replace our application’s browser router with a HashRouter. The hash component of the URL is used by this router to keep the UI in sync with the URL.

2.  Create the routes:

Create a routes folder and the required routes. These routes can be configured in the app.js file. But first, let’s create a Navbar component that can be visible on all pages.

1. Create a Navbar component:

import { Link } from "react-router-dom"
const Navbar = () => {
  return (
    <div>
      <Link to="/">Home</Link>
      <Link to="/about">About</Link>
      <Link to="/careers">Careers</Link>
    </div>
  )
}
export default Navbar;

Now we can add the Navbar component alongside the configured routes in the app.js file.

1. Set up routes in the app.js file:

import './App.css';
import { Routes, Route} from "react-router-dom";
import About from "./routes/About";
import Careers from "./routes/Careers";
import Home from "./routes/Home";
import Navbar from './Navbar';
function App() {
  return (
    <>
      
      
        } />
        } />
        } />
      
    </>
  );
}
export default App;

Now that we’re done with the setup, let’s push our code, like so:

git add .
git commit -m "setup gh-pages"
git push

Next, we simply deploy, and our app should route properly:

npm run deploy

Once these steps are completed, our deployed application will correctly route the user to any part of the application they desire.

Setting up a preview environment

When we configure Netlify deployments, we’re given a preview link to view our deployment before it is merged into the main branch. Let’s create the same for GitHub Pages.

We’ll use a simple tool called Livecycle for this, which saves us the trouble of having to do this using GitHub Actions. Every time we make a pull request in our repository, Livecycle assists us in creating a preview environment.

To create a preview environment, follow these steps:

1. Set up a Livecycle account; I recommend signing up with your GitHub account
2. Configure a new project and connect it to GitHub
3. Once you’ve connected to GitHub and granted Livecycle all the access it needs, you can select the repository you want to set up the preview on:
4. Select a template based on your project’s tech stack. For our example, we’d select Create React App NPM, as our project was built using create-react-app:
5. Review the configuration and deploy. For our example, we don’t need to add anything to the configurations:

Once deployment is successful, anytime we make a PR or push a commit to that PR, we’ll get a preview link.

Automating deployment with GitHub Actions

We would proceed to integrate GitHub Actions for automated deployments. This streamlines the deployment process and enhances efficiency. Before we can deploy the app using this approach, we’ll create a workflow file in .github/workflows/deploy.yml:

---

---

name: Deploy to GitHub Pages

on:
  push:
    branches:
      - main
  workflow_dispatch:

permissions:
  contents: write
  pages: write
  id-token: write

jobs:
  build-and-deploy:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout Repository
        uses: actions/checkout@v4

      - name: Setup Node
        uses: actions/setup-node@v4
        with:
          node-version: "20"
          cache: "npm"

      - name: Install Dependencies
        run: npm ci

      - name: Build
        run: npm run build

      - name: Deploy
        uses: JamesIves/github-pages-deploy-action@v4
        with:
          folder: build
          branch: gh-pages

This workflow file is used by GitHub Actions to determine how to run the jobs. The workflow does the following:

• Checkout repository — Fetches the code from your GitHub repository
• Setup Node — Installs Node.js version 20 with npm caching for faster installations
• Install dependencies — Installs the project dependencies using npm ci
• Build — Builds the React application with any environment variables included
• Deploy — Uses the JamesIves GitHub Pages deploy action to push the built files to the gh-pages branch

Next, run this:

git add . && git commit -m "Adds Github Actions" && git push

This will start the pipeline and proceed to deploy the built files to pages:

If you get an error: Branch "main" is not allowed to deploy to github-pages due to environment protection rules, follow these steps:

1. Go to your repository Settings
2. Click on Environments
3. Select your environment, github-pages
4. Next to Deployment branches, select Selected branches from the dropdown
5. Click on Add deployment branch rule
6. Enter the pattern main

This should allow deployments from the main branch to your github-pages environment:

After adding this, retry the deploy stage, and this time it should pass successfully:

Using environment variables and secrets

Sometimes, we need to add sensitive data to applications. But to do it securely, we don’t want to hardcode it directly into the application. Let’s see how to do this with the help of GitHub Actions.

To demonstrate this, we’ll update the About.js pages to include an environment variable, add a React environment variable to GitHub as a secret, and finally add this sensitive data securely to the workflow file:

To add a new secret to GitHub, go to:

1. Settings → Secrets and Variables → Actions
2. Click the Secrets tab and click the Create New repository secret button
3. Use REACT_APP_API_KEY as the secret name, and 12345 as the secret value
4. Lastly, click on the Add Secret button:

Next, modify the workflow file to include this environment variable. This enables the variable REACT_APP_API_KEY to be available to pages within the app:

name: Deploy to GitHub Pages

on:
  push:
    branches:
      - main
  workflow_dispatch:

permissions:
  contents: write
  pages: write
  id-token: write

jobs:
  build-and-deploy:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout Repository
        uses: actions/checkout@v4

      - name: Setup Node
        uses: actions/setup-node@v4
        with:
          node-version: "20"
          cache: "npm"

      - name: Install Dependencies
        run: npm ci

      - name: Build
        run: npm run build
        env:
          REACT_APP_API_KEY: ${{ secrets.REACT_APP_API_KEY }}

      - name: Deploy
        uses: JamesIves/github-pages-deploy-action@v4
        with:
          folder: build
          branch: gh-pages

Finally, update the About.js page to this:

const apiKey = process.env.REACT_APP_API_KEY;
const About = () => {
  return <h1>About page 1.0, Secret: {apiKey}</h1>;
};
export default About;

Once deployed, we can see the environment variable displayed on the page:
