Automatic build and release app with Github actions

Create your own CI/CD pipeline with Github actions for free, deploy your Ionic Capacitor JS app every time you push to main.

This tutorial focuses on the GitHub hosting, but you can adapt it with little tweak to any other CI/CD platform.


Be sure you have added your Capacitor app first to Capgo, this tutorial just focuses on the upload phase. If you need to add your app to Capgo, you can follow this Tutorial

Commit convention

First you need to start following the commit convention conventional commits` this will help the tooling understand how to upgrade the version number, it’s 5 min to learn it.

Conventional commits

GitHub actions for tag

Then you have to create your first GitHub action to automatically build and create tag.

Create a file at this path: .github/workflows/bump_version.yml

with this content:

name: Bump version
- main
if: "!startsWith(github.event.head_commit.message, 'chore(release):')"
runs-on: ubuntu-latest
name: "Bump version and create changelog with standard version"
- name: Check out
uses: actions/checkout@v4
fetch-depth: 0
token: '${{ secrets.PERSONAL_ACCESS_TOKEN }}'
- name: Git config
run: |
git config --local "github-actions[bot]"
git config --local "github-actions[bot]"
- name: Create bump and changelog
run: npx capacitor-standard-version
- name: Push to origin
run: |
CURRENT_BRANCH=$(git rev-parse --abbrev-ref HEAD)
remote_repo="https://${GITHUB_ACTOR}:${{ secrets.PERSONAL_ACCESS_TOKEN }}${GITHUB_REPOSITORY}.git"
git pull $remote_repo $CURRENT_BRANCH
git push $remote_repo HEAD:$CURRENT_BRANCH --follow-tags --tags

This will release a tag for every commit in your main branch. And add a changelog entry for each commit in the main branch in

Don’t worry if you don’t have this file, it will be created for you.

To make this work, create a PERSONAL_ACCESS it in your GitHub secret as PERSONAL_ACCESS_TOKEN.

This is necessary to let the CI commit the changelog.

When you create the token, choose expiration as never and the scope as repo.

Lastly, set the version in your package.json file, sync it with your Native version number that will facilitate, then next step.

This is only necessary the first time, then the tools will keep it up to date.

You can now commit this both files and see your first tag appear in GitHub!

Both native and web platform will have the version number bump after each commit.

GitHub actions for build

Create a file at this path: .github/workflows/build.yml

with this content:

name: Build source code and send to Capgo
- '*'
runs-on: ubuntu-latest
name: "Build code and release"
- name: Check out
uses: actions/checkout@v4
- name: Install dependencies
id: install_code
run: npm i
- name: Build
id: build_code
run: npm run build
env: # Remove both lines if you don't need it
FIREBASE_CONFIG: ${{ secrets.FIREBASE_CONFIG }} # Exemple of env var coming from a secret
- name: Create Release
id: create_release
run: npx @capgo/cli@latest bundle upload -a ${{ secrets.CAPGO_TOKEN }} -c production

This will install and build your dependency before sending it to Capgo.

If your command for build is different, you can change it in the build_code step.

To make this work, you need to get your API key for Capgo, add it in the secret of your GitHub repository as CAPGO_TOKEN.

You can now commit this both files and see your first tag appear in GitHub!

Add the commit will generate a new build for the production channel.

You should add your test in the build step to ensure your code is working.

Go To your Capgo dashboard and check your build who just appeared, you now have your CI/CD system.

If you want to let all of your users get the update whenever it’s available, go to your channel and set it to public.
