Describe the issue

The imports doesn't work with latest Typescript versions with moduleResolution:"node16"

I did instigate on this and used

npx @arethetypeswrong/cli --from-npm @automapper/[email protected]

It does following output

👺 Import resolved to an ESM type declaration file, but a CommonJS JavaScript file. https://github.com/arethetypeswrong/arethetypeswrong.github.io/blob/main/docs/problems/FalseESM.md

🥴 Import found in a type declaration file failed to resolve. Either this indicates that runtime resolution errors will occur, or (more likely) the types misrepresent the contents of the JavaScript files. https://github.com/arethetypeswrong/arethetypeswrong.github.io/blob/main/docs/problems/InternalResolutionError.md

Seems both CJS and ESM are broken for node16 resolution mode.

Any plans to tackle this @nartc? or did you figure it out @iamchathu

[iamchathu]

@driley-abbvie Nope. I tried patching the module but seems have to do lot of work to get done manually. Better to setup something like tsup to generate seperate type definitions for both module types

Even the latest version has the same issue.

npx @arethetypeswrong/cli --from-npm @automapper/[email protected]
