# ==========================================
# GitHub Actions Workflow: Continuous Integration
# ==========================================
#
# 功能：持续集成测试和代码质量检查
#
# 触发条件：
#   - Pull Request 创建或更新
#   - 推送到 main 分支
#
# 工作流程：
#   1. 依赖安装和缓存
#   2. 运行测试套件
#   3. TypeScript 类型检查
#   4. ESLint 代码检查
#   5. 验证构建成功
#
# 目的：
#   - 确保所有代码变更通过质量检查
#   - 在合并前发现潜在问题
#   - 保持代码库健康

    steps:
      # ------------------------------------------
      # 步骤 1: 检出代码
      # ------------------------------------------
      - name: 📥 Checkout repository
        uses: actions/checkout@v4

      # ------------------------------------------
      # 步骤 2: 设置 pnpm
      # ------------------------------------------
      - name: 📦 Setup pnpm
        uses: pnpm/action-setup@v4
        with:
          version: 9.15.4

      # ------------------------------------------
      # 步骤 3: 设置 Node.js
      # ------------------------------------------
      - name: 🔧 Setup Node.js
        uses: actions/setup-node@v4
        with:
          node-version: ${{ env.NODE_VERSION }}

      # ------------------------------------------
      # 步骤 4: 安装依赖
      # ------------------------------------------
      - name: 📦 Install dependencies
        run: pnpm install --frozen-lockfile

      # ------------------------------------------
      # 步骤 5: 运行完整 CI 流程（质量检查 + 构建）
      # ------------------------------------------
