rollup-plugin-commonjs-named-exports v1.0.2

rollup-plugin-commonjs-named-exports

Re-export CommonJS named exports using Node.js cjs-module-lexer.

Useful to allow import { Fragment, useState } from "react"; (instead of forcing import React from "react";) instance for a bundled React as the source package still re-exports its CJS named exports based on process.env.NODE_ENV:

// react/index.js
if (process.env.NODE_ENV === "production") {
  module.exports = require("./cjs/react.production.min.js");
} else {
  module.exports = require("./cjs/react.development.js");
}
// react/cjs/react.development.js
// ...
exports.Fragment = REACT_FRAGMENT_TYPE;
exports.useReducer = useReducer;
exports.useRef = useRef;
exports.useState = useState;
// ...

Based on esinstall and jspm-rollup.
