Oh good catch. The __esModule property should be ignored if the file is .cjs.

This will be pretty complex to handle since it should handle:

• Relative path:import('./file.cjs')
• Import subpath: import('#file') where #file maps to file.cjs
• TS paths alias: import('file') where file maps to file.cjs

Feel free to open a PR with a test first, but I think this will be very challenging and may have to be resolved with https://github.com/privatenumber/tsx/issues/614
