qs@1.0.0+ is now maintained by the awesome hapijs team at hapijs/qs. Please direct any new issues and concerns in that repository!

query string parser for node and the browser supporting nesting, as it was removed from 0.3.x, so this library provides the previous and commonly desired behaviour (and twice as fast). Used by express, connect and others.

$ npm install qs

var qs = require('qs');
qs.parse('user[name][first]=Tobi&user[email]=tobi@learnboost.com');
// => { user: { name: { first: 'Tobi' }, email: 'tobi@learnboost.com' } }
qs.stringify({ user: { name: 'Tobi', email: 'tobi@learnboost.com' }})
// => user[name]=Tobi&user[email]=tobi%40learnboost.com
