如何使用 babel 插件将 commonjs 转换为 es2015 模块？

Question

I use the webpack2 to build my web and I want to benefit from tree-shaking, which only works with es2015 modules.

So I want to ask for commonjs to es2015 transformer of babel plugin like this rollup plugin https://github.com/rollup/rollup-plugin-commonjs .

Answer 1

One such plug-in is babel-plugin-transform-commonjs-es2015-modules. It can be installed by running:

npm install babel-plugin-transform-commonjs-es2015-modules

Then add 'plugins':['transform-commonjs-es2015-modules'] to your babel configuration.
