Node.js: How to find out the path to an arbitrary file?

Question

JavaScript

There is no js file.
Need to know the path to this file, for example, "C:/<...>/file.txt"?
Tell me, please, how to solve the problem?
Looking ahead, there are "__filename" and "__dirname" functions, but they give the path to the executable js file.

Answer 1

Maybe the path module will help?

var path = require('path');
path.resolve(__dirname, filename);  // Относительный путь до файла от текущей директории

Answer 2

Either look for ready-made modules for searching files, or write a search yourself, or try to call some system functions (like "find" in unix)
