Show HN: tsconfig-to-dual-package – support CommonJS and ESM in one package

[azu]

This tool helps you to create Dual CommonJS/ES module packages. (dual package is a package that can be used from CommonJS and ESM)

It is hard to create dual package in only TypeScript Compiler(`tsc`) because TypeScript do not change import file path by their design goal. This tool create Dual Package by using some tricks in package.json without additional transpiling.
