Package Exports

fast-querystring
fast-querystring/lib/index.js

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 (fast-querystring) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

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']
// }
