> Create nested getter properties and any intermediary dot notation (`'a.b.c'`) paths
Please consider following this project's author, [Brian Woodward](https://github.com/doowb), and consider starring the project to show your :heart: and support.
## Install
Install with [npm](https://www.npmjs.com/):
```sh
$ npm install --save set-getter
```
## Usage
```js
var getter = require('set-getter');
```
set-getter works like [set-value](https://github.com/jonschlinkert/set-value) by adding a property to an object or an object hierarchy using dot notation. The main difference is that the property is added using `Object.defineProperty` and is expected to be a getter function that returns a value.
**Example**
```js
var obj = {};
// root level property
getter(obj, 'foo', function() {
return 'bar';
});
console.log(obj.foo);
//=> 'bar'
// property dot notation
getter(obj, 'bar.baz', function() {
return 'qux';
});
console.log(obj.bar.baz);
//=> 'qux'
// property array notation
getter(obj, ['beep', 'boop'], function() {
return 'bop';
});
console.log(obj.beep.boop);
//=> 'bop'
```
## API
