Question/idea: Not bundled .d.ts tree for monorepos

[lveillard]

Hello! One frustrating thing when clicking on a type or function imported from another package in the same monorepo when using tsup is that clicking on the functions or types make you jump to the bundled code instead of the original .ts file.

I found this to be an alternative:

// package.json scripts
dev: "tsc --emitDeclarationOnly && tsup --watch --sourcemap"

//tsup config
  dts: false,
  clean: false,

This lets tsc create the tree of types, and tsup just bundle the .js and .mjs. This way you can freely jump into any original ts file.

However, using tsc is slow.

Is there any way to achieve the same only with tsup? Maybe a missing feature?

Something like bundleDeclarations: false would be great for DX and could even be automatic while tsup --watch is active
