```
var func = vm.runInNewContext('(function(){\'do not use strict\';\nvar net = require(\"net\");\n\nconsole.log(\"NET\");\n})', {require: require, console: console})
func()
```
That said, passing require to external code is unsafe, so you'll probably want to whitelist modules that code is allowed to require.

--@Conrad - yes, i am trying this out on the same node.js server now. but eventually the goal is to ship the code to a node.js client where the sent code could run. Earlier I did write it to a file and then 'require' it. That obviously works. Are there better methods of doing this?@Ryan - This is a simpler json string example below. This too does not work for me when i run: recData["runFunction"]();{"runFunction":"function(){'use strict';\nvar net = require(\"net\");\n\nconsole.log(\"NET\");\n}"}

It's much easier for us to help you if you give us enough information to easily reproduce the problem on our own systems.
