npm install jsonselect;

Options:

• only: string|array - List of whitespace delimited paths (returned object will only contain those paths)
• except: string|array - List of whitespace delimited paths (returned object will not contain those paths)

Options can also be a string. See examples.

Paths can be (almost) any JSONPath.

var select = require('jsonselect');

var a = select(obj, 'username email name.first friends -friends.password');
// equivalent to
var a2 = select(obj, { only: 'username email name.first friends', except: 'friends.password'} );

var b = select(obj, '-password'); // everything except password
// equivalent to
var b2 = select(obj, { except: 'password' });

Coming soon!

• better parser for normalized paths
• properly delete array element using splice/concat
