ts-node paths issue

This repository showcases an issue in running a simple TS app using tsconfig paths configuration, with ts-node.

PS C:\src\sample-paths\app\function> npm run start

> function@1.0.0 start
> ts-node index.ts

Error: Cannot find module 'entities/SimpleClass'

}

Changes that make it work:

• Set baseUrl to . in tsconfig.base.json
• Duplicate the paths in app/function/tsconfig.json:

"paths": {
  "entities/*": ["../entities/*"],
}

Reproduction

1. Clone the repo
2. Run npm install in the root and in app/function
3. Run npm run start in app/function

There are a couple of logs available with the different configurations:

• not-working.txt - the default configuration
• base-url.txt - the configuration using baseUrl in tsconfig.base.json
• duplicate.txt - the configuration duplicating the paths in app/function/tsconfig.json
