  • 移除 useEffect 等在服务端不执行的代码，再移除无用的 import
  • 增加用户配置，修改构建 SSR 时 @babel/preset-env 插件中 targets.node 版本，减少 babel 的语法转换
  • 实际使用中，部分场景 platform-loader 没有生效

babel 语法转化这个对构建速度的影响应该也还好，目前只编译源码不会编译 node_modules，你指的是更高级语法对性能更好？如果业务有自己的诉求可以在 build.json 配置：https://rax.js.org/docs/guide/build-config#browserslist

platform-loader 这个可以参考「跨端三方包研发规范」这个 RFC

关于这点我又想了一下，node 的 targets 和 web 的 targets 得允许用户单独配置，不然 node 的 targets 会影响 web

使用 "Modern JavaScript" 对体积和性能的影响可以参考这里
