# native-url
A lightweight implementation of Node's [url](http://nodejs.org/api/url.html) interface atop the [URL API](https://developer.mozilla.org/en-US/docs/Web/API/URL). Use it instead of the `url` module to reduce your bundle size by around 7.5 kB.
Weighs **1.6 kB gzipped**, works in Node.js 7+ and [all modern browsers](https://caniuse.com/#feat=mdn-api_url):
![Chrome 32, Firefox 19, Safari 7, Edge 12, Opera 19](https://badges.herokuapp.com/browsers?googlechrome=32&firefox=19&safari=7&microsoftedge=12&opera=19)
Older browsers can be [easily polyfilled](#polyfill-for-older-browsers) without new browsers loading the code.
## Installation
```sh
npm i native-url
```
## Usage
```js
const url = require('native-url');
url.parse('https://example.com').host // example.com
url.parse('/?a=b', true).query // { a: 'b' }
```
### Usage with Webpack
When you use the `url` module, webpack bundles [`node-url`](https://github.com/defunctzombie/node-url) for the browser. You can alias webpack to use `native-url` instead, saving around 7.5kB:
```js
// webpack.config.js
module.exports = {
// ...
resolve: {
alias: {
url: 'native-url'
}
}
}
```
The result is **functionally equivalent** in Node 7+ and all modern browsers.
### Usage with Rollup
Rollup does not bundle shims for Node.js modules like `url` by default, but we can add `url` support via `native-url` using aliases:
```js
// rollup.config.js
import resolve from 'rollup-plugin-node-resolve';
import alias from '@rollup/plugin-alias';
module.exports = {
// ...
plugins: [
resolve(),
alias({
entries: {
url: 'native-url'
}
})
]
};
```
With this in place, `import url from 'url'` will use `native-url` and keep your bundle small.
## API
Refer Node's [legacy url documentation](https://nodejs.org/api/url.html#url_legacy_url_api) for detailed API documentation.
### `url.parse(urlStr, [parseQueryString], [slashesDenoteHost])`
Parses a URL string and returns a URL object representation:
```js
url.parse('https://example.com');
// {
// href: 'http://example.com/',
// protocol: 'http:',
// slashes: true,
// host: 'example.com',
// hostname: 'example.com',
// query: {},
// search: null,
// pathname: '/',
// path: '/'
// }
url.parse('/foo?a=b', true).query.a; // "b"
```
### `url.format(urlObj)`
Given a parsed URL object, returns its corresponding URL string representation:
```js
url.format({ protocol: 'https', host: 'example.com' });
// "https://example.com"
```
### `url.resolve(from, to)`
Resolves a target URL based on the provided base URL:
```js
url.resolve('/a/b', 'c');
// "/a/b/c"
url.resolve('/a/b', '/c#d');
// "/c#d"
```
## Polyfill for Older Browsers
`native-url` relies on the DOM [URL API](https://developer.mozilla.org/en-US/docs/Web/API/URL) to work. For older browsers that don't support the `URL` API, a [polyfill](https://www.npmjs.com/package/url-polyfill) is available.
Conveniently, a polyfill is never needed for [browsers that support ES Modules](https://caniuse.com/#feat=es6-module), so we can use `<script nomodule>` to conditionally load it for older browsers:
```html
<script nomodule src="/path/to/url-polyfill.js"></script>
```
