Compiler API to resolve path from ImportDeclaration

Hi there, since TS supports paths in tsconfig.json, is there an API in the compiler (Program, CompilerHost or something) to programmatically resolve real path of an import?

I wrote this transformer https://github.com/longlho/ts-transform-css-modules and it's tripping up on paths that are aliased in tsconfig.json, e.g:

import * as css from 'alias/foo.css'

tsconfig.json

{
  "compilerOptions": {
    "paths": {
      "alias/*": "../../../some_location/*"
    }
  }
}

I can try to manually reconstruct TS resolver but rather not to.

Thanks!

Comienza revisando las APIs de Program y CompilerHost del compilador, junto con el comportamiento de la configuración paths descrito en el issue. Compara la resolución solicitada de ImportDeclaration con el resolver existente de TypeScript, usando el transformador de CSS-modules enlazado como contexto. Se considera terminado cuando el compilador expone una forma compatible de resolver rutas de importación con alias sin reconstruir manualmente la resolución.
