- 6 个框架源文件搬到 src/, 加 src/index.ts barrel 作为公共 API 入口 - package.json 标 private, main/types 指 src/index.ts (ts-node 消费方编译) - 加 vitest + 22 条单元测试 (ILabel / MemoryShrimpCrud) 全通过 - examples/basic-admin/ 用 MemoryShrimpCrud 跑零 Mongo 依赖 demo 待办: ShrimpServer 强耦合 Mongo+JWT+Express, crudRegistry 用 .model 判断数据源, 这两个问题在 demo 中已暴露, 计划后续重构补到 90 分。

|
* Shrimp basic-admin demo
|
|
*
|
|
* 用 MemoryShrimpCrud 跑一个零依赖的 admin server,展示:
|
|
* - Shrimp 核心(模块注册 / RPC dispatch / 权限树)
|
|
* - ShrimpTableModule + MemoryShrimpCrud 的 CRUD 自动事件
|
|
* - 通过 Express 暴露成 HTTP RPC
|
|
*
|
|
* 不使用 ShrimpServer/Mongoose/JWT,刻意暴露 ShrimpServer 把太多东西耦合在
|
|
* Express+Mongo+Auth 一起的事实,作为后续重构的对照样本。
