To address CI/CD deployment in trackjs/javascript-gameshow, the current setup does not incorporate a Continuous Integration/Continuous Deployment (CI/CD) pipeline. The deployment process requires attention to ensure optimization and automation.

Current Deployment Process

Deployment for the audience app is managed through npm scripts defined in the audience-app/package.json:

{
  "name": "audience-app",
  "scripts": {
    "start": "firebase serve",
    "use:project": "firebase use javascript-gameshow && firebase target:clear hosting audience-app && firebase target:apply hosting audience-app javascript-gameshow",
    "deploy": "npm run use:project && firebase deploy",
    "deployReset": "npm run deploy && npm run data",
    "data": "firebase database:set / ./database.template.json",
    "lock": "firebase --config firebase.lockdown.json deploy"
  },
  "devDependencies": {
    "firebase-tools": "11.16.1"
  }
}

Steps for Deployment

1. Install Firebase Tools: Ensure that Firebase command-line tools are installed globally.

   $ npm install -g firebase-tools
   

2. Deploying the Application: Use the following command to deploy the audience app.

   $ npm run deploy
   

   This command utilizes a two-step process:

   • Set Project Configuration: The command firebase use javascript-gameshow switches to the appropriate Firebase project.
   • Deploy to Firebase Hosting: The command firebase deploy is invoked to deploy the application.

3. Resetting Deployment: To deploy the application and reset the Firebase data, execute:

   $ npm run deployReset
   

   This command first runs npm run deploy, followed by npm run data, which initializes the database with a template.

4. Running the Application Locally: For local testing, the server can be started with:

   $ npm start
   

   The application will be accessible at http://localhost:5000/.

Next Steps for CI/CD Integration

1. Choose a CI/CD Tool: Consider tools like GitHub Actions, CircleCI, or Travis CI for managing the CI/CD pipeline.

2. Create CI/CD Configuration: Set up a configuration file that defines the CI/CD process, which typically includes stages such as:

   • Build: Install dependencies and compile TypeScript.
   • Test: Run unit tests using Jest.
   • Deploy: Execute the deployment script.

3. Automate Deployment on Push: Configure the CI/CD tool to automatically deploy the application upon pushing to the main branch.

4. Monitor for Errors: Integrate error tracking to ensure smooth deployments and quickly address issues.

Sample CI Configuration (Hypothetical)

A basic configuration for GitHub Actions might look like the following:

name: CI/CD Pipeline

on:
  push:
    branches:
      - main

jobs:
  build:
    runs-on: ubuntu-latest

    steps:
      - name: Checkout Code
        uses: actions/checkout@v2

      - name: Install Dependencies
        run: npm install

      - name: Run Tests
        run: npm run test
      
      - name: Deploy Application
        run: npm run deploy
        env:
          FIREBASE_TOKEN: ${{ secrets.FIREBASE_TOKEN }}

The above example assumes a Firebase token stored in GitHub secrets to authenticate with Firebase.

By implementing these steps, the project can achieve a robust CI/CD deployment structure effectively.
