Installation
registry=npm install vm-browserify@1.1.2"vm-browserify": "1.1.2"About this package
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
