Thanks.

Why reproduction is required

[qinyouzhi]

The code cannot be provided at the moment. The company code cannot be uploaded due to computer control.

I configured dts.alias. The build error disappeared, but a new problem occurred. The type file generated by dts will include the reference package in alias.

Minimal reproduction does not equal to real projects. I can not understand what include the reference package in alias means without reprod demo.

run: pnpm --filter=@package-a run build

This is a basic tsc usage problem, Rslib fully respects with the results of tsc since it use TypeScript Compiler API to generate declaration files.

You can run npx tsc -p tsconfig.build.json --noEmit false --emitDeclarationOnly --declaration --outDir dist in packages/a to verify this behaviour.

Your paths are written in the tsconfig.json of the root directory, and the actual configuration used is the tsconfig.build.json in packages/a folder. paths is resolved based on baseUrl, so at least you should set paths in packages/a/tsconfig.build.json with correct relative path to packages b or use ${configDir} feature to avoid can not find module diagnostic.

And include the reference package in alias should be AS EXPECTED in tsc since it is out of baseUrl.

Usually we don't set up tsconfig at the root of the monorepo to use source code as paths but rather based on project reference to do such things. I think you can refer some famous monorepo repositories in the community to learn about related organizational methods.

We temporarily close this issue due to out of scope of Rslib.

Do you have any reference recommendations? Thanks

I made the changes according to the above configuration, but still got the error [Cannot find module '@package-b' or its corresponding type declarations.]
