GitHub Actions for Firebase

This Action for firebase-tools enables arbitrary actions with the firebase command-line client.

Inputs

• args - Required. This is the arguments you want to use for the firebase cli

Environment variables

• FIREBASE_TOKEN - Required if GCP_SA_KEY is not set. The token to use for authentication. This token can be aquired through the firebase login:ci command.

• GCP_SA_KEY - Required if FIREBASE_TOKEN is not set. A base64 encoded private key (json format) for a Service Account with the Firebase Admin role in the project, and if your deploying functions you would also need the Cloud Functions Developer role. And since the deploy service account is using the App Engine default service account in the deploy process, it also needs the Service Account User role. If your only doing Hosting Firebase Hosting Admin is enough.

• PROJECT_ID - Optional. To specify a specific project to use for all commands, not required if you specify a project in your .firebaserc file.

• PROJECT_PATH - Optional. The path to the folder containing firebase.json if it doesn't exist at the root of your repository. e.g. ./my-app

Example

To authenticate with Firebase, and deploy to Firebase Hosting:

name: Build and Deploy
on:
  push:
    branches:
      - master

jobs:
  build:
    name: Build
    runs-on: ubuntu-latest
    steps:
      - name: Checkout Repo
        uses: actions/[email protected]
      - name: Install Dependencies
        run: npm install
      - name: Build
        run: npm run build-prod
      - name: Archive Production Artifact
        uses: actions/[email protected]
        with:
          name: dist
          path: dist
  deploy:
    name: Deploy
    needs: build
    runs-on: ubuntu-latest
    steps:
      - name: Checkout Repo
        uses: actions/[email protected]
      - name: Download Artifact
        uses: actions/[email protected]
        with:
          name: dist
          path: dist
      - name: Deploy to Firebase
        uses: w9jds/[email protected]
        with:
          args: deploy --only hosting
        env:
          FIREBASE_TOKEN: ${{ secrets.FIREBASE_TOKEN }}

Alternatively:

        env:
          GCP_SA_KEY: ${{ secrets.GCP_SA_KEY }}

If you have multiple hosting environments you can specify which one in the args line. e.g. args: deploy --only hosting:[environment name]

If you want to add a message to a deployment (e.g. the Git commit message) you need to take extra care and escape the quotes or the YAML breaks.

        with:
          args: deploy --message \"${{ github.event.head_commit.message }}\"

Recommendation

If you decide to do seperate jobs for build and deployment (which is probably advisable), then make sure to clone your repo as the Firebase-cli requires the firebase repo to deploy (specifically the firebase.json)
