# lazy-req [](https://travis-ci.org/sindresorhus/lazy-req)
|
||
|
|
|
||
|
|
> Require modules lazily
|
||
|
|
|
||
|
|
|
||
|
|
## Install
|
||
|
|
|
||
|
|
```
|
||
|
|
$ npm install --save lazy-req
|
||
|
|
```
|
||
|
|
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
```js
|
||
|
|
// pass in `require` or a custom require function
|
||
|
|
var lazyReq = require('lazy-req')(require);
|
||
|
|
var _ = lazyReq('lodash');
|
||
|
|
|
||
|
|
// where you would normally do
|
||
|
|
_.isNumber(2);
|
||
|
|
|
||
|
|
// you now instead call it as a function
|
||
|
|
_().isNumber(2);
|
||
|
|
|
||
|
|
// it's cached on consecutive calls
|
||
|
|
_().isString('unicorn');
|
||
|
|
|
||
|
|
// extract lazy variations of the props you need
|
||
|
|
var members = lazyReq('lodash')('isNumber', 'isString');
|
||
|
|
|
||
|
|
// useful when using destructuring assignment in ES2015
|
||
|
|
const { isNumber, isString } = lazyReq('lodash')('isNumber', 'isString');
|
||
|
|
|
||
|
|
// works out of the box for functions and regular properties
|
||
|
|
var stuff = lazyReq('./math-lib')('sum', 'PHI');
|
||
|
|
console.log(stuff.sum(1, 2)); // => 3
|
||
|
|
console.log(stuff.PHI); // => 1.618033
|
||
|
|
```
