which-module

Find the module object for something that was require()d

Find the module object in require.cache for something that was require()d or imported - essentially a reverse require() lookup.

Useful for libs that want to e.g. lookup a filename for a module or submodule that it did not require() itself.

Install and Usage

npm install --save which-module

const whichModule = require('which-module')

console.log(whichModule(require('something')))
// Module {
//   id: '/path/to/project/node_modules/something/index.js',
//   exports: [Function],
//   parent: ...,
//   filename: '/path/to/project/node_modules/something/index.js',
//   loaded: true,
//   children: [],
//   paths: [ '/path/to/project/node_modules/something/node_modules',
//            '/path/to/project/node_modules',
//            '/path/to/node_modules',
//            '/path/node_modules',
//            '/node_modules' ] }

API

whichModule(exported)

Return the module object, if any, that represents the given argument in the require.cache.

exported can be anything that was previously require()d or imported as a module, submodule, or dependency - which means exported is identical to the module.exports returned by this method.

If exported did not come from the exports of a module in require.cache, then this method returns null.
