JSPM – querystringparser@0.1.1

Package Exports

querystringparser
querystringparser/js/querystringserializer

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (querystringparser) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

#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.
