👋 Hi and thank you so much for your work ❤️ 🤟🏼

Description

tsup is not resolving typescript absolute imports. I have a tsconfig.json that defines multiple absolute imports (see below). tsup bundles it without resolving for those absolute imports, so it causes errors when consuming the lib in other projects.

In your docs, I can see NormalizedOptions - which uses tsconfigResolvePaths - but when I try to put it in my config (see below) typescript gets angry 😠:

'tsconfigResolvePaths' does not exist in type 'Options | Options[] | ((overrideOptions: Options) => MaybePromise<Options | Options[]>)'

tsconfig.json:

"compilerOptions": {
    "baseUrl": ".",
    "paths": {
      "@services/*": [
        "./services/*"
      ],
      "@vendors/*": [
        "./vendors/*"
      ],
// ....
    },

tsup.config.json:

import { defineConfig } from 'tsup';

export default defineConfig({
  entry: {
    index: 'index.ts',
    'services/marketing/index': 'services/marketing/index.ts',
    'vendors/index': 'vendors/index.ts',
  },
  tsconfig: './tsconfig.json',
  splitting: false,
  sourcemap: true,
  clean: true,
});
