Description

Hi!

I'm using tsup in watch mode for a shared library in a monorepo. I can't get the d.ts generation working in watch mode.

My config

  "tsup": {
    "entry": [
      "src/index.ts",
      "src/models/index.ts",
      "src/validators/index.ts"
    ],
    "format": [
      "esm",
      "cjs"
    ],
    "dts": true,
    "splitting": false,
    "sourcemap": true,
    "clean": false
  }

Output after saving a file

^ Note that this output doesn't mention dts file and when

Workaround

I'm currently using tsup --onSuccess script option to run tsc to get the d.ts files. I'd prefer a built-in solution since this requires me to align tsup and tsc config everytime I'm adding a module

Info

    "tsup": "~7.2.0",
    "typescript": "~5.1.6"

Thanks!
