# vm-browserify
emulate node's vm module for the browser
[](https://ci.testling.com/substack/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
result =
```
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
```
