Build and Deploy Next.js App to GitHub Pages

Use this workflow in your Next Project to build and deploy your static sites on Github

Introduction

By default, next export will generate an out directory, which can be served by any static hosting service or CDN like GitHub Pages. But the name of inner directories (like _next/) and chunk files start with underscore and GitHub Pages return 404 for such files. Next Pages automatically rename those files and folders, remove the beginning underscore and replace the new URL in your source code. Also, Next Pages rename your out directory to docs.

Setup GitHub Pages

Build Command

Update the build command of your package.json as shown below.

{
  "scripts": {
    "build": "next build && next export"
  }
}

npm run build could be used to build and export static pages.

Create GitHub Action

Create build.yml file in .github/workflows/ folder.

Example:

└──.github
    └── workflows
        └── build.yml

Include the following steps in the end of a build job.

- name: Next Pages
  uses: anorcle/next-pages@v1.0
- name: Commit and push changes
  run: |
    git config --global user.name "anorcle"
    git config --global user.email "next-pages@anorcle.com"
    git add -A
    git commit -m "New Build"
    git push

You can replace your username and email for above git commit.
