Single path transformation

[RebeccaStevens]

Is it possible to programmatically get the replacement path from a given input path.

const replacementPath = getReplacement("#/app/foo");
console.log(replacementPath) // => ./src/foo.js

{
  "compilerOptions": {
    "baseUrl": ".",
    "paths": {
      "#/app/*": ["src/*"],
    }
  }
}
