/**
|
|||
|
|
* 图标注册表静态校验(构建前门禁)。
|
|||
|
|
*
|
|||
|
|
* 为什么需要:
|
|||
|
|
* 本项目的 Element Plus 图标是按**字符串名**全局引用的 —— 菜单/路由配置里的 `icon: 'Odometer'`、
|
|||
|
|
* 按钮上的 `:icon="'Search'"`、`<component :is="item.icon">`,以及模板里的 `<el-icon><School /></el-icon>`。
|
|||
|
|
* 为了让主 chunk 不为 293 个图标里的 250 个死代码买单,两端改成**按需注册**
|
|||
|
|
* (`packages/web-admin/src/icons.ts`、`packages/desktop-client/src/renderer/icons.ts`)。
|
|||
|
|
*
|
|||
|
|
* 代价是:新增视图时用了一个没注册的图标,Vue 只会打一条 warning、界面上**静默渲染成空白** ——
|
|||
|
|
* 这类问题在 verify:web / verify:desktop 里都不容易暴露。因此在这里做一次静态校验,
|
|||
|
|
* 有遗漏就 exit 1,把失败挪到构建阶段。
|
|||
|
|
*
|
|||
|
|
* 用法:node scripts/check-icons.mjs (已挂进两端 package.json 的 build 脚本)
