Thanks for your dogfooding~

The 'minify' option seems to be ineffective

minify was forcibly disabled by default and currently we does not support overriding it through configuration.

No ESM product was generated

Rslib is still in its early (dogfooding) stages. We plan to provide it to community users in one or two months.
Now it still depends on a canary version of Rspack to make it work correctly.

Compared to TSUP, the speed seems to have not improved

We haven't done any performance optimization yet, and the main time-consuming step I think is probably tsc generating types.
