## README

# react-native-fast-url

A Fast URL and URLSearchParams Polyfills for React Native.

Built in JSI and [ada](https://github.com/ada-url/ada), a WHATWG-compliant and fast URL parser adopted in Node.js since v18.16 for the best performance.

Tested on RN [0.76](https://github.com/KusStar/react-native-fast-url/tree/main/example), [0.80](https://github.com/KusStar/react-native-fast-url/tree/main/example80), **new architecture** supported(https://github.com/KusStar/react-native-fast-url/pull/9). Thanks to [https://github.com/Doublemme](https://github.com/Doublemme) for the contribution.

The legecy branch is still available in the [legacy](https://github.com/KusStar/react-native-fast-url/tree/legacy) branch.

## Installation

```sh
npm install react-native-fast-url
yarn add react-native-fast-url
```

Benchmark code in example: [bench.ts](./example/src/bench.ts)

This library(Ada) significantly outperforms `react-native-url-polyfill` in terms of speed, fully embracing the WHATWG URL standard and Unicode Standards. However, it's essential to note that Ada's bundle size is larger compared to `react-native-url-polyfill`. The binary size of the Ada C++ library is approximately **500KB**, while `react-native-url-polyfill` is a more compact **73.67KB**. The choice between the two should be based on your specific requirements and preferences.

## Usage

Import the polyfill in your entry file:

```js
// index.js
import 'react-native-fast-url/polyfill';
```

Or if you want to use it only in some files:

```js
import { URL, URLSearchParams } from 'react-native-fast-url';
```
