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 `import`ed - 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

## <tt>whichModule(exported)</tt>

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 `import`ed 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`.
