# skeemas-json-pointer

Lightweight implementation of [JSON Pointers](https://tools.ietf.org/html/rfc6901)

## Install

```bash

npm install skeemas-json-pointer

```

## Pointers for Getting Values

```js

var jsonPointer = require('skeemas-json-pointer');

// Getting values

jsonPointer('#/foo').get({ foo:'bar' }); 

// =>'bar'

jsonPointer('#/nested/foo').get({ 

	nested: { foo:'bar' }

}); 

// =>'bar'

jsonPointer('#/nested/foo/1').get({ 

	nested: { foo:['bar','bat','baz'] }

}); 

// =>'bat'

```

## Pointers for Setting Values

```js

var subject = { 

	nested: { foo:'bar' },

	list: [0, 1, 2]

};

// Change a property value

jsonPointer('#/nested/foo').set(subject, 'baz'); 

// Change an array item

jsonPointer('#/list/1').set(subject, 'one'); 

// Append an array item

jsonPointer('#/list/-').set(subject, 'last'); 

assert.deepEqual(subject, {

	nested: { foo:'baz' },

	list: [0, 'one', 2, 'last']

});

```
