Expected Behavior

I work in a Typescript mono-repo, where all our imports are bare imports instead of relative imports. We define exports and imports in package.json to control what each package exports. It would be great if tsoa knew how to resolve these imports.

See https://github.com/JavaScriptBach/tsoa-repro for an example.

Current Behavior

tsoa does not know how to resolve these imports:

Generate routes error.

Steps to Reproduce

Context (Environment)

Version of the library: 6.4.0
Version of NodeJS: 18.14.0

• Confirm you were using yarn not npm: [x]

Detailed Description

It would be nice if tsoa understand how to resolve these fields:

• https://nodejs.org/api/packages.html#exports
• https://nodejs.org/api/packages.html#subpath-imports
• https://nodejs.org/api/packages.html#conditional-exports

These fields have been around since ~Node 12 and all major tooling (e.g. Typescript, bundlers) know how to understand them.

Currently, I can hack around this issue by passing custom tsconfig options to tsoa. But this is not ideal because I have to define the import paths in 2 different locations (package.json and in tsoa).

Breaking change?

This could break generation depending on what users have defined in their exports or imports in package.json.

Is the file that declares the User model included in tsc's files?

Why does tsc matter here? The rules to resolve the imports are defined in package.json.
