 # vm-browserify

 emulate node's vm module for the browser

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

 # example

 Just write some client-side javascript:

 ``` js
 var vm = require('vm');

 $(function () {
     var res = vm.runInNewContext('a + 5', { a : 100 });
     $('#res').text(res);
 });
 ```

 compile it with [browserify](http://github.com/substack/node-browserify):

 ```
 browserify entry.js -o bundle.js
 ```

 then whip up some html:

 ``` html
 <html>
   <head>
     <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
     <script src="/bundle.js"></script>
   </head>
   <body>
     result = <span id="res"></span>
   </body>
 </html>
 ```

 and when you load the page you should see:

 ```
 result = 105
 ```

 # methods

 ## vm.runInNewContext(code, context={})

 Evaluate some `code` in a new iframe with a `context`.

 Contexts are like wrapping your code in a `with()` except slightly less terrible
 because the code is sandboxed into a new iframe.

 # install

 This module is depended upon by browserify, so you should just be able to
 `require('vm')` and it will just work. However if you want to use this module
 directly you can install it with [npm](http://npmjs.org):

 ```
 npm install vm-browserify
 ```
