GitHub Actions Firebase App Deployment Automated | Devops Junction

GitHub Actions makes it easy to automate all your software workflows with GitHub’s own CI/CD.

Now you can build, test, and deploy your code right from GitHub.

GitHub Actions offer free minutes of usage and storage per month so if you want to use GitHub Actions beyond the minutes or storage included in your account, you will be billed for additional usage.

In this article, we are going to Github Actions Firebase deployment example and how to build and deploy to firebase using Github Actions.


Creating the .yml file

Under the .github/workflows folder in your project, create a file named build.yml

Choose the branch to run the workflow

name: react native app deployment
      - main

Here, I have chosen the main branch to run the workflow. You can change it to whichever branch or branches you want the workflow to run.

Installing dependencies and specifying the jobs

Now we install the dependencies and specify the VM to run our jobs.

    runs-on: ubuntu-latest
      - uses: actions/checkout@v2
      - name: Install npm dependencies
        run: |
          npm install

Setting up Gradle cache

Gradle cache helps to keep the builds faster by caching the Gradle dependencies and Gradle wrapper.

    - name: Cache Gradle Wrapper
      uses: actions/cache@v2
        path: ~/.gradle/wrapper
        key: ${{ runner.os }}-gradle-wrapper-${{ hashFiles('gradle/wrapper/') }}

    - name: Cache Gradle Dependencies
      uses: actions/cache@v2
        path: ~/.gradle/caches
        key: ${{ runner.os }}-gradle-caches-${{ hashFiles('gradle/wrapper/') }}
        restore-keys: |
          ${{ runner.os }}-gradle-caches-

Generate the Android release build

    needs: install-and-test
    runs-on: ubuntu-latest
      - uses: actions/checkout@v2
      - name: Install npm dependencies
        run: |
          npm install
      - name: Build Android Release
        run: |
          cd android && ./gradlew assembleRelease

⚠️ The build will be different if you want to publish to Google Playstore.

Upload the artifact

GitHub Actions allow us to save the output of its jobs. This file can be downloaded and saved as a backup file or can be used for testing.

      - name: Upload Artifact
        uses: actions/upload-artifact@v2
          name: artifact
          path: android/app/build/outputs/apk/release/app-release.apk


Deploying the app to Firebase App Distribution

Before you push the changes after configuring the upload-android job, there are a few things you have to do.

To deploy to Firebase App Distribution, you need two tokens. These tokens will be saved under GitHub Secrets and will help you connect the workflow to Firebase.

  • ${{secrets.FIREBASE_APP_ID_ANDROID}} This is the app ID which you can find from the firebase console under project settings. Go to the Firebase console > Click on the project settings from the top left navigation bar> Scroll to the bottom to find the app ID.

  • ${{secrets.FIREBASE_TOKEN}}  This is a token which you can get after configuring firebase on your local machine and then running firebase login:ci to generate the token.

Once you get these two tokens, save them under Secrets in GitHub Secrets.

Click on New repository secret and enter the secret name and its respective value which you just found.

As a final step before adding the code, make a group in App Distribution under Testers & Groups so that you can release the app to your testers.

Finally, you can finish the workflow by adding the following code:

    needs: build-android
    runs-on: ubuntu-latest
      - name: Download artifact
        uses: actions/download-artifact@v2
          name: artifact
      - name: upload artifact to Firebase App Distribution
        uses: wzieba/Firebase-Distribution-Github-Action@v1
          appId: ${{secrets.FIREBASE_APP_ID_ANDROID}}
          token: ${{secrets.FIREBASE_TOKEN}}
          groups: android_testers
          file: app-release.apk


Voila !. The workflow will now run and deploy the app via Firebase App distribution whenever a change is made to your repository.
