Build Status


🔥 Note this is early experimental! 实验阶段的主要工作是想办法让整体架构变稳定、简洁,不建议上生产。


wean 是一个小程序编译器前端,它负责将标准的微信小程序打包成 fre 代码,这样做有很多好处——

  • 小程序引擎 - 将打包产物跑到 APP webview 上,就可以成为专属小程序,如“携程小程序”
  • 开箱即用 - 更现代的标准,更短的开发链路,从某种程度上缓解微信小程序的历史包袱
  • 跨端 - 以保住微信为前提,一套代码,支持所有小程序端

wean 生成 fre 代码,借助 esbuild 做 js 的打包

Demo

Run

$ npm install
$ npm link
$ wean

Motivation

在 wean 之前,大量小程序工具使用 babel + webpack 进行打包,各种 loader 、plugin 导致整个开发链路变长,O(n^n) 一遍又一遍的 ast 遍历,复杂度指数级增长,编译耗时超级长,调试也超级困难

wean 旨在解决链路问题,它自研编译器和打包器,整体复杂度维持在 O(n),没有任何 AST 操作,同一个小程序项目,wean 大约比 taro(+webpack)快一百倍
