I require a module that was installed via npm. I want to access a .js file subordinate to that module (so I can subclass a Constructor method in it). I can't (well, don't want to) modify the module's code, so don't have a place to extract its __dirname.
I am aware of the following question, but it is about getting the path of a module that one has code control over (hence, __dirname is the solution): In Node.js how can I tell the path of `this` module?
~~~
Even better would be to get the module's loaded module info

These modules can be loaded into the program by using the require function. Syntax: var module = require('module_name'); The require() function will return a JavaScript type depending on what the particular module returns.
js: var fs = require('fs') var newPath = "E:\\Thevan"; var oldPath = "E:\\Thevan\\Docs\\something. mp4"; exports. uploadFile = function (req, res) { fs. readFile(oldPath, function(err, data) { fs.
Importing from core modules: These modules are inbuilt in Node. js and can be imported as: const var = require('fs');
If I correctly understand your question, you should use require.resolve():
Use the internal require() machinery to look up the location of a module, but rather than loading the module, just return the resolved filename.
Example: var pathToModule = require.resolve('module');
