querystringparser

0.1.1 • Public • Published

Build Status

Introduction

Extremely fast querystring parser with same API and semantics as qs + DoS Protection.

Quick start

npm install querystringparser
var querystringparser = require("querystringparser");
querystringparser.parse("foo=bar");

API

Exactly the same API and semantics are implemented 100% to make comparison fair.

DoS protection checks for input length, amount of total keys and maximum nesting depth of keys.

var qs = require("querystringparser");
qs.maxLength //Maximum amount of characters in the input string to parse: 32768
qs.maxKeys //Maximum amount of key-value pairs in the query string: 256
qs.maxDepth //Maximum nesting depth of keys: 4 e.g. a[b][c][d]=3

a RangeError is thrown when these limits are reached.

Performance

To run benchmarks run the bench bash script while on the project root.
