A CLI tool for refactoring an existing NodeJs application to a fully functional TypeScript application.

import { Node, ReferencedSymbol, ReferenceFindableNode } from 'ts-morph';

/*
* this solves the problem in some cases with findReferences() crashing when calling it
* on a Node that is defined outside of the project (e.g. node_modules, globals).
* example:
* console.log("something");
*
* does not work on class extending a default class such as
* class CustomError extends Error {
  name;
  constructor(message) {
    super(message);
    this.name = this.constructor.name;
  }
}
* */
