I’ve been moving many repositories over to GitHub Actions to automate deployment and testing. One of my projects uses GitHub Pages, but includes data from two different branches:
- The
mainbranch contains the bulk of the website - The
app-challengebranch contains a second site that appears under a/heleon/path
Using GitHub Actions, I set up the site pull from both branches before deploying. The script looks like this:
name: Deploy from two branches
on:
push:
branches: [main]
jobs:
build:
runs-on: ubuntu-latest
steps:
# Checkout the `main` branch
- uses: actions/checkout@v2
# Install Node.js
- uses: actions/setup-node@v2-beta
with:
node-version: '14'
# Install npm dependencies
# (similar to npm install)
- run: npm ci
# Run code to build the site files inside the `big-island-buses` folder
- run: npm run build
# Checkout the `app-challenge` branch
- uses: actions/checkout@v2
with:
ref: app-challenge
# Put the checked out files inside the `big-island-buses/heleon` folder
path: big-island-buses/heleon
clean: false
# Delete the .git folder from `big-island-buses/heleon`
# This turns the files into a plain folder instead of a git repository
- run: rm -rf big-island-buses/heleon/.git
# Deploy the `big-island-buses` folder to GitHub Pages
- uses: peaceiris/actions-gh-pages@v3
with:
github_token: ${{ secrets.GITHUB_TOKEN }}
publish_dir: "./big-island-buses"
user_name: 'github-actions[bot]'
user_email: 'github-actions[bot]@users.noreply.github.com'
The first sequence of steps checks out the main branch, installs Node.js and npm dependencies, then runs the build script. The files created by the build script end up in a folder named big-island-buses.
The second sequence checks out the app-challenge branch, and places the files inside a folder named heleon, which is a subfolder of big-island-buses. These files are static so they don’t have a separate build script.
However, putting one git repository inside another like this creates problems for the GitHub Pages script. Deleting the .git folder turns the git repository into a plain folder.
