[Bug]: export is not correct when using rspack to output a library in esm about rspack

[ahabhgk]

Yes, output.library.type = 'commonjs-static' should already fixed in the main branch, the fix will be released in v0.7.0

and @JSerFeng will fix the mangleExports soon, should also be released in v0.7.0

Seems to be a bug of optimization.mangleExports, cc @JSerFeng

should use info.used_name here?

Btw, I also tried to output files in cjs but failed.
I can not get something like module.exports = { t as hello }; but only an IIFE.
Could you give me an example for how to configure rspack to output files in cjs in library mode?

try to set output.library.type = "commonjs2" like:

/** @type {import("@rspack/core").Configuration} */
module.exports = {
  output: {
    library: {
      type: "commonjs2"
    }
  },
};

Thanks! I got what I want by setting output.library.type to commonjs2 or commonjs.

But I found another diff which may be a bug.
When setting output.library.type to commonjs-static, there is a diff like this.

// v0.5.9
var r = n('294');
(exports.handler = r.handler), Object.defineProperty(exports, '__esModule', { value: !0 });

// v0.6.5
n('294'),
Object.defineProperty(exports, '__esModule', { value: !0 });

Just reporting.
