        # Specify the Node.js versions you want to test against
        node-version: [20.x] # You can add more like [18.x, 20.x]

    steps:
      # 1. Checkout Code
      - name: Checkout repository
        uses: actions/checkout@v4

      # 2. Setup Node.js Environment
      - name: Set up Node.js ${{ matrix.node-version }}

          node-version: ${{ matrix.node-version }}

      # 3. Install Dependencies
      # Use 'ci' for cleaner, faster, deterministic installs based on lockfile
      - name: Install dependencies
        run: npm ci

      # 4. Check Formatting

      # 7. Build
      # Optional if your tests run directly on TS files (e.g., using ts-jest, ts-node)
      # But usually good practice to ensure the build itself works.
      - name: Build project

      # 8. Testing
      # Uncomment when we have tests.
