vm-browserify

emulate node's vm module for the browser

# example

Just write some client-side javascript:

var vm = require('vm');
window.addEventListener('load', function () {
var res = vm.runInNewContext('a + 5', { a : 100 });
document.querySelector('#res').textContent = res;
});

compile it with browserify:

browserify entry.js -o bundle.js

then whip up some html:

<html>
<head>
<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:

npm install vm-browserify
