fast-querystring

fast-querystring

Fast query-string parser to replace the deprecated node:querystring parse function.

Installation

npm i --save fast-querystring

Features

• 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']}

Differences

• Key & value with length 0 is omitted by default
  • foo=bar&hey parses into {foo: 'bar'}, but node:querystring returns {foo: 'bar', hey: ''}

Usage

const QueryString = require('fast-querystring')
const qs = QueryString.parse('hello=world&foo=bar&values=v1&values=v2')

console.log(qs)
// {
//   hello: 'world',
//   foo: 'bar',
//   values: ['v1', 'v2']
// }
