1. 单独使用TypeScript的complier来对ts代码进行转换 要使用TS的编译器,必须要安装typescript依赖,因为typescript包中集成了complier工具,这是因为TS这门语言在一开始指定的时候就预料到了浏览器可能会不支持ts语法,所以一开始就开发了专门用于将ts编译为js代码的tsc工具。 npm i typescript -D 然后使用命令对ts文件...

@babel/plugin-syntax-jsx @babel/plugin-transform-react-jsx @babel/plugin-transform-react-display-name 比如es2015 是一套规范,包含很多转译插件。如果每次要开发者一个个添加并安装,配置文件很长不说,npm install的时间也会很长,为了解决这个问题,babel 还提供了一组插件的集合。因为常用,所以不必重复定义 & ...

https://github.com/babel/babel/blob/master/packages/babel-plugin-transform-flow-strip-types/src/index.jsis also instructive As you can tell by the source code, the Babel parser understands Flow syntax, not TypeScript syntax, then they strip it out later. It's pretty baked in (seehttps:/...

但最近的 JS 提案中已经允许了这种新的写法(让代码 diff 更加清晰)。为了避免 babel 报错,就需要增加语法插件babel-plugin-syntax-trailing-function-commas 当我们添加转译插件之后,在转换这一步把源码转换并输出。这也是我们使用 babel 最本质的需求。
