# get-id

[![Build Status](https://travis-ci.org/janeklb/get-id.svg?branch=master)](https://travis-ci.org/janeklb/get-id)

Keep track of your JS objects (and functions) via a unique id.

Install:

```bash

npm install --save get-id

```

Usage:

```javascript

import getid from 'get-id'

// or:

// var getid = require('get-id');

var object  = {},

    object2 = {};

var objid  = getid(object);

var obj2id = getid(object2);

objid  === getid(object);

obj2id === getid(object2);

```

### What's happening?

`getid` assigns an id (int) to a non-enumerable, non-writable property on the

passed object or function under the key `__object_id__`, and then returns it.

### Using a custom id property name

If for whatever reason you don't want to use the `__object_id__` key, you can

generate a custom `getid` function using the exported `create` function:

```javascript

import { create as create_getid } from 'get-id';

const customgetid = create_getid('__this_is_a_custom_key');

const object = {};

const objectid = customgetid(object);

objectid === object['__this_is_a_custom_key'];

```
