# set-value [![NPM version](https://img.shields.io/npm/v/set-value.svg?style=flat)](https://www.npmjs.com/package/set-value) [![NPM monthly downloads](https://img.shields.io/npm/dm/set-value.svg?style=flat)](https://npmjs.org/package/set-value) [![NPM total downloads](https://img.shields.io/npm/dt/set-value.svg?style=flat)](https://npmjs.org/package/set-value) [![Linux Build Status](https://img.shields.io/travis/jonschlinkert/set-value.svg?style=flat&label=Travis)](https://travis-ci.org/jonschlinkert/set-value)

> Create nested values and any intermediaries using dot notation (`'a.b.c'`) paths.

## Install

Install with [npm](https://www.npmjs.com/):

```sh
$ npm install --save set-value
```

## Usage

```js
var set = require('set-value');
set(object, prop, value);
```

### Params

* `object` **{object}**: The object to set `value` on
* `prop` **{string}**: The property to set. Dot-notation may be used.
* `value` **{any}**: The value to set on `object[prop]`

## Examples

Updates and returns the given object:

```js
var obj = {};
set(obj, 'a.b.c', 'd');
console.log(obj);
//=> { a: { b: { c: 'd' } } }
```

### Escaping

**Escaping with backslashes**

Prevent set-value from splitting on a dot by prefixing it with backslashes:

```js
console.log(set({}, 'a\\.b.c', 'd'));
//=> { 'a.b': { c: 'd' } }

console.log(set({}, 'a\\.b\\.c', 'd'));
//=> { 'a.b.c': 'd' }
```

**Escaping with double-quotes or single-quotes**

Wrap double or single quotes around the string, or part of the string, that should not be split by set-value:

```js
console.log(set({}, '"a.b".c', 'd'));
//=> { 'a.b': { c: 'd' } }

console.log(set({}, "'a.b'.c", "d"));
//=> { 'a.b': { c: 'd' } }

console.log(set({}, '"this/is/a/.file.path"', 'd'));
//=> { 'this/is/a/file.path': 'd' }
```

### Bracket support

set-value does not split inside brackets or braces:

```js
console.log(set({}, '[a.b].c', 'd'));
//=> { '[a.b]': { c: 'd' } }

console.log(set({}, "(a.b).c", "d"));
//=> { '(a.b)': { c: 'd' } }

console.log(set({}, "<a.b>.c", "d"));
//=> { '<a.b>': { c: 'd' } }

console.log(set({}, "{a..b}.c", "d"));
//=> { '{a..b}': { c: 'd' } }
```

## History

### v2.0.0

* Adds support for escaping with double or single quotes. See [escaping](#escaping) for examples.
* Will no longer split inside brackets or braces. See [bracket support](#bracket-support) for examples.

If there are any regressions please create a [bug report](../../issues/new). Thanks!
