Suggestion

I have been deving an automation publish tool, with typescript inside. Nice work for you!

Since the tsconfig.json file need to be put in a center config folder other than project/source code root. amd i have tried to use tsc --watch --project path-to-tsconfig.json to make this future, which is not working for now.

I got TS18003 error, and i know why this happen: tsc just want to remind us we may have a wrong include or exclude config. 😄 I cannot find any tsc command should i use to conject with --project option to specify the project root.

I find in the tsc sourcecode that the compiler.parseJsonConfigFileContent(_, _, basePath); function could let us specify the project basePath when parsing tsconfig.json, so, i want to ask if we can expose a command option to let use the same function as basePath, maybe --configFileBasePath or --configContext?

Please let me know if there already is a solution for my use case.

Thank you for your works!

Examples

tsc --project path-to-tsconfig.json --configContext path-to-source-code-root

Checklist

My suggestion meets these guidelines:

• This wouldn't be a breaking change in existing TypeScript / JavaScript code
• This wouldn't change the runtime behavior of existing JavaScript code
• This could be implemented without emitting different JS based on the types of the expressions
• This isn't a runtime feature (e.g. new expression-level syntax)

Comienza con el manejo de tsc --project y la llamada a compiler.parseJsonConfigFileContent mencionada en el issue. Traza cómo las rutas de tsconfig.json determinan la ruta base del proyecto y cómo se produce TS18003. Se considera terminado cuando una opción de comando documentada puede especificar una raíz de código fuente independiente para una configuración en una carpeta arbitraria, con pruebas que cubran la invocación de ejemplo.
