* Verdaccio 缓存可视化管理面板 — 后端服务入口
|
||
* Express + better-sqlite3，§4.2 REST API
|
||
*
|
||
* 环境变量：
|
||
* VERDACCIO_STORAGE Verdaccio 缓存目录（优先于 UI 设置）
|
||
* PORT 监听端口（默认 3000）
|
||
* DATA_DIR SQLite 数据目录（默认 backend/data）
|
||
* VCM_USERNAME 面板登录账号（默认 admin）
|
||
* VCM_PASSWORD 面板登录密码（默认 666666，Docker 部署务必通过 compose 覆盖）
|
||
* UV_THREADPOOL_SIZE libuv IO 线程池大小（默认 4 → 8：扫描/stat/readFile 并发更高，NAS 四核安全）
|
||
*
|
||
* 模块划分：
|
||
* - scan-manager.js 扫描状态机与业务编排（缓存/进度/状态构建）
|
||
* - schedules.js 每日扫描 + 每周抓榜定时任务
|
||
* - routes/* REST 路由（按领域拆分）
|
||
