Automate your Firebase's CI with GitHub Actions

Use GitHub Actions to deploy a Firebase Project.

Prerequisites

node
yarn
docker

Create a Firebase's Project

Cloud Functions for Firebase let you automatically run backend code in response to events triggered by Firebase features and HTTPS requests.

Follow the steps on the Get Started tutorial
Run yarn global add firebase-tools to install firebase-tools locally
Run firebase login to log in via the browser and authenticate the firebase tool
Go to your Firebase project directory
Run firebase init functions

Firebase Token

Generate an authentication token for use in non-interactive environments.

Get the $FIREBASE_TOKEN on firebase-tools by running: firebase login:ci

GitHub Secrets (Environment variables)

Secrets are encrypted environment variables created in a repository and can only be used by GitHub Actions.

On GitHub, navigate to the main page of the repository
Under your repository name, click [Settings]
In the left sidebar, click [Secrets]
Click on [Add a new secret] and add the generated Firebase Token with the name FIREBASE_TOKEN
Click on [Add a new secret] and add the Firebase's Project Name with the name FIREBASE_PROJECT_NAME

GitHub Actions Configuration

GitHub Actions enables you to create custom software development lifecycle workflows directly in your GitHub repository.

On GitHub, navigate to the main page of the repository
Under your repository name, click [Actions]
Find the "Popular continuous integration workflows" section
Find the "Node.js" workflow
Click on "Set up this workflow"
On Edit new file paste
