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.
npm install --save which-module
```js 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' ] } ```
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.
