Node Sandbox

A nifty javascript sandbox for node.js.

Some features

• Can be used to execute untrusted code.
• Support for timeouts (e.g. prevent infinite loops)
• Handles errors gracefully
• Restricted code (cannot access node.js methods)
• Supports console.log and print utility methods

Example

Be sure to check out example/example.js

var s = new Sandbox()
s.run( '1 + 1 + " apples"', function( output ) {
  // output.result == "2 apples"
})

Documentation

Basic syntax: sandbox_instance.run( code, hollaback )

code is the string of Javascript to be executed.

hollaback is a function, and it's called with a single argument, output.

output is an object with two properties: result and console. The result property is an inspected string of the return value of the code. The console property is an array of all console output.

For example, given the following code:

function add( a, b ){
  console.log( a )
  console.log( b )
  return a + b
}
add( 20, 22 )

The resulting output object is:

{ result: "42"
, console: [ "20", "22" ]
}

Installation & Running

Let's get it! The easiest way is through npm:

npm install sandbox

Or if you'd like to play with the code, see the examples, run the tests, what-the-fuck-ever...

git clone git://github.com/gf3/sandbox.git

And run some examples:

node example/example.js

Tests

To run the tests simply run the test file with node.

node test/sandbox_test.js
