Vite 构建产物体积优化

当首屏加载慢 (FCP > 1.5s) 时，通常需要检查 JS Bundle 的体积。

1. 产物分析 (Visualizer)

首先"看见"哪些包最大。

npm install rollup-plugin-visualizer -D

2. 常用优化策略

路由懒加载 (Route Lazy Loading)

这是收益最大的优化点。

❌ import UserList from './views/UserList.vue' ✅ component: () => import('./views/UserList.vue')

依赖分包 (Manual Chunks)

将大型库（ECharts, bkui-vue）单独打包，避免 vendor hash 频繁变化。

按需引入 (Tree Shaking)

❌ import _ from 'lodash' ✅ import debounce from 'lodash-es/debounce'

Gzip 压缩

npm install vite-plugin-compression -D
