文档笔记

当前在Next13版本中可以使用Turbopack，且处于Alpha版本，且没有独立出来的库，项目上慎用。

概念

Turbo 增量打包引擎，可重用的基于Rust的库
rust是系统级编程语言，对标准C和C++，更安全，不容易发生内存泄漏
函数级别的缓存

缓存至内存中，因此重启服务，缓存被清除
启动时长

Tubopack使用SWC来打包JS或TS文件，(webpack 也是用来swc)默认支持如下语法/功能：js/ts/jsx/tsx/Browserlist/css module/postcss-nested/css @import/HMR/Public directory/CommonJS/ESM/Dynamic Imports**/Environment variables且Live reloading**,etc.
不支持babel/vue/Svelte/PostCSS/SCSS/LESS/Tailwind CSS/TS Checketc.

Vite

使用esbuild， esbuild没有HMR，没有cache，没有lazy bundling
在dev模式不会bundle，以来浏览器的ES Modules system
不足：大项目会出现大量的网络请求，性能瓶颈
