Next.js GitHub Pages

Deploy Next.js to GitHub Pages with GitHub Actions. View the deployed app 🚀

Now with Next.js App Router support! If you need Pages Router support click here.

⚠️ Heads up! GitHub Pages does not support serverless or edge functions. This means dynamic functionality will be disabled. See all the unsupported features.

Configure Next.js

Next.js Config

First, you need to configure Next.js to deploy static exports. This is required for GitHub Pages to work.

1. Open the next.config.ts file
2. Add the following:

/** @type {import('next').NextConfig} */
const nextConfig = {
  /**
   * Enable static exports for the App Router.
   *
   * @see https://nextjs.org/docs/app/building-your-application/deploying/static-exports
   */
  output: "export",

  /**
   * Set base path. This is the slug of your GitHub repository.
   *
   * @see https://nextjs.org/docs/app/api-reference/next-config-js/basePath
   */
  basePath: "/nextjs-github-pages",

  /**
   * Disable server-based image optimization. Next.js does not support
   * dynamic features with static exports.
   *
   * @see https://nextjs.org/docs/app/api-reference/components/image#unoptimized
   */
  images: {
    unoptimized: true,
  },
};

export default nextConfig;

3. Save the next.config.ts

4. Finally, place a .nojekyll file in the /public directory to disable GitHub Pages from trying to create a Jekyll website.

.
├── app/
├── public/
│   └── .nojekyll
├── next.config.js

Perfect! This is all you need to configure Next.js to deploy on GitHub Pages.

Add base path to page.tsx

Next, you will need to add the base path to images in page.tsx file. This is required for the images to appear on GitHub Pages.

1. Open app/page.tsx
2. Find the Image components
3. Add /nextjs-github-pages/ (or the slug of your GitHub repository) to the src prop:

   <Image
     src="/nextjs-github-pages/vercel.svg"
     alt="Vercel Logo"
     className={styles.vercelLogo}
     width={100}
     height={24}
     priority
   />

4. Save the page.tsx file

Configure GitHub Repository

Next you need to configure Github for automated deployments via GitHub Actions.

Enable GitHub Pages

The following settings use the Github Action Deploy Pages to deploy. I prefer this workflow because you don't need to generate SSH keys or use a personal access token.

1. Go to your repository's Settings tab
2. Click "Pages" in the sidebar
3. Under "Build and Deployment", select "GitHub Actions" as the source:

Setup GitHub Action

This is where the magic happens! This workflow file will automatically build and deploy the app when you push to the main branch.

1. Create .github/workflows/deploy.yml file
2. Paste the contents of https://github.com/gregrickaby/nextjs-github-pages/blob/main/.github/workflows/deploy.yml
3. Save the deploy.yml file

Push to GitHub

Now that everything is configured, you can commit your code and push to GitHub. This will trigger the GitHub Action workflow and deploy your app to GitHub Pages.

git add . && git commit -m "Initial commit" && git push

You should see your site deployed to GitHub Pages in a few minutes. 🚀
