优化内容

1. TypeScript增量类型检查

tsc 改为 tsc --incremental --tsBuildInfoFile node_modules/.tsbuildinfo

  • 将类型检查结果缓存在 node_modules/.tsbuildinfo
  • 下次构建时只重新检查改动的文件
  • 缓存文件随 npm docker volume 持久化，跨run复用

预期收益：小改动PR类型检查从~25s→~5s（-80%）

2. Vite持久化构建缓存

vite.config.ts 中新增 build.cache: true

  • Vite将模块transform结果缓存到 node_modules/.vite/build-cache/
  • 未改动的模块直接从缓存读取，跳过transform
  • 同样随 npm volume 持久化

预期收益：小改动PR构建从~90s→40-60s（-3050%）

整体预期

Build frontend assets 步骤从 ~120s → 50-70s（-4058%）

改动文件

  • apps/web/vite.config.ts - 启用 build.cache
  • .gitea/workflows/ci-cd.yml - staging/production web构建都加了--incremental

验证方式

  1. 首次构建：基线耗时（生成缓存）
  2. 第二次构建（无代码改动）：验证缓存命中，耗时应明显下降
  3. 小改动构建：验证部分缓存命中

风险

  • 极低。增量构建是官方稳定特性，缓存不一致时删除node_modules即可恢复
