+# import-from [![Build Status](https://travis-ci.org/sindresorhus/import-from.svg?branch=master)](https://travis-ci.org/sindresorhus/import-from)
+
+> Import a module like with [`require()`](https://nodejs.org/api/modules.html#modules_require_id) but from a given path
+
+
+## Install
+
+```
+$ npm install import-from
+```
+
+
+## Usage
+
+```js
+const importFrom = require('import-from');
+
+// There is a file at `./foo/bar.js`
+
+importFrom('foo', './bar');
+```
+
+
+## API
+
+### importFrom(fromDirectory, moduleId)
+
+Like `require()`, throws when the module can't be found.
+
+### importFrom.silent(fromDirectory, moduleId)
+
+Returns `undefined` instead of throwing when the module can't be found.
+
+#### fromDirectory
+
+Type: `string`
+
+Directory to import from.
+
+#### moduleId
+
+Type: `string`
+
+What you would use in `require()`.
+
+
+## Tip
+
+Create a partial using a bound function if you want to import from the same `fromDir` multiple times:
+
+```js
+const importFromFoo = importFrom.bind(null, 'foo');
+
+importFromFoo('./bar');
+importFromFoo('./baz');
+```
