fast-querystring's Introduction

fast-querystring

Test codecov NPM version

Fast query-string parser and stringifier to replace the legacy node:querystring module.

Installation

npm i fast-querystring

Features

  • Supports both parse and stringify methods from node:querystring module
  • Parsed object does not have prototype methods
  • Uses & separator as default
  • Supports only input of type string
  • Supports repeating keys in query string
    • foo=bar&foo=baz parses into {foo: ['bar', 'baz']}
  • Supports pairs with missing values
    • foo=bar&hola parses into {foo: 'bar', hola: ''}
  • Stringify does not support nested values (just like node:querystring)

Usage

const qs = require('fast-querystring')

// Parsing a querystring
console.log(qs.parse('hello=world&foo=bar&values=v1&values=v2'))
// {
//   hello: 'world',
//   foo: 'bar',
//   values: ['v1', 'v2']
// }

// Stringifying an object
console.log(qs.stringify({ foo: ['bar', 'baz'] }))
// 'foo=bar&foo=baz'

Benchmark

All benchmarks are run using Node.js v20.2.0 running on M1 Max.
