[![NPM version](https://img.shields.io/npm/v/fast-querystring.svg?style=flat)](https://www.npmjs.com/package/fast-querystring)

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

```javascript
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.
