+# which-module
+
+> Find the module object for something that was require()d
+
+[![Build Status](https://travis-ci.org/nexdrew/which-module.svg?branch=master)](https://travis-ci.org/nexdrew/which-module)
+[![Coverage Status](https://coveralls.io/repos/github/nexdrew/which-module/badge.svg?branch=master)](https://coveralls.io/github/nexdrew/which-module?branch=master)
+[![Standard Version](https://img.shields.io/badge/release-standard%20version-brightgreen.svg)](https://github.com/conventional-changelog/standard-version)
+[![Greenkeeper badge](https://badges.greenkeeper.io/nexdrew/which-module.svg)](https://greenkeeper.io/)
+
+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
+```
+
+```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' ] }
+```
+
+## API
+
+### `whichModule(exported)`
+
+Return the [`module` object](https://nodejs.org/api/modules.html#modules_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`.
