详解vite如何支持cjs方案示例

// react 入口文件
// 只有 CommonJS 格式
if (process.env.node_ENV === "production") {
  module.exports = require("./cjs/react.production.min.js");
} else {
  module.exports = require("./cjs/react.development.js");
}

function __require() {
    // 压缩后
    return mod || (0, test)((mod = { exports: {} }).exports, mod), mod.exports;
    // 压缩前，仅推测
    if (mod) {
      	return mod
    } else {
        test(mod, mod.exports)
        return mod.exports
    }
};
function test(exports, mod) {
    console.log('exports, mod', exports, mod)
}

// Named export/import
export { name }
import { name } from "name"
// Default export/import
export default name
import name from "name"

let name = {
  firstName,
  lastName
}
module.exports = name
mudule.export.firstName = 'z'
exports.lastName = 'zz'

var esm$1 = { exports: {} };
(function (module, exports) {
  module.exports = () => {};
  exports.a = 3;
  exports.b = 4;
})(esm$1, esm$1.exports);
var esm = esm$1.exports;
export { esm as default };
