querystring.node.js

This node module provides robust querystring parsing and stringifying. It is based heavily on the YUI QueryString module located here.

Acknowledgements

Thanks to Isaac Schlueter for pointing me to the YUI code and allowing me to tweak it for node.js.

querystring.js

Exports the parse and stringify methods from the querystring-parse and querystring-stringify sub-modules, repsectively.

parse example

var sys = require("util");
var qs = require("querystring-yui");

var str = qs.parse("foo=bar&baz=qux");
sys.puts(JSON.stringify(str)); // => {"foo":"bar","baz":"qux"}

str = qs.parse("foo[bar][][bla]=baz");
sys.puts(JSON.stringify(str)); // => {"foo":{"bar":[{"bla":"baz"}]}}

str = qs.parse(["foo[2][bar]=baz&foo[2][bla]=blo");
sys.puts(JSON.stringify(str)); // => {"foo":{"2":{"bar":"baz","bla":"blo"}}}],

stringify example

var sys = require("util");
var qs = require("querystring-yui");

var obj = {"foo":"bar","baz":"qux"};
sys.puts(qs.stringify(obj)); // => foo=bar&baz=qux

obj = {"foo":{"bar":[{"bla":"baz"}]}};
sys.puts(qs.stringify(obj)); // => foo%5Bbar%5D%5B%5D%5Bbla%5D=baz

obj = {"foo":{"2":{"bar":"baz","bla":"blo"}}};
sys.puts(qs.stringify(obj)); // => foo[2][bar]=baz&foo[2][bla]=blo
