# @polka/url [](https://npmjs.org/package/@polka/url) [](https://licenses.dev/npm/%40polka%2Furl)
|

|
|
> Super fast, memoized `req.url` parser; _not_ limited to [Polka][polka]!
|
|
|
|
Parses the `url` from a [`IncomingMessage`](https://nodejs.org/api/http.html#http_class_http_incomingmessage) request. The returned object will always only contain the following keys: `search`, `query`, `pathname`, and `raw`.
|
|
|
|
> **Note:** This library does not process `protocol`, `hostname`, `port`, etc.<br>This is because the incoming `req.url` value only begins with the path information.
|
|
|
|
Parsed requests will be mutated with a `_parsedUrl` key, containing the returned output. This is used for future memoization, avoiding the need to fully parse the same `url` value multiple times.
|
|
|
|
## Install
|
|
|
|
```
|
|
$ npm install --save @polka/url
|
|
```
|
|
|
|
## Usage
|
|
|
|
```js
|
|
const parse = require('@polka/url');
|
|
|
|
let req = {
|
|
url: '/foo/bar?fizz=buzz'
|
|
};
|
|
let output = parse(req);
|
|
//=> {
|
|
//=> pathname: '/foo/bar',
|
|
//=> raw: '/foo/bar?fizz=buzz',
|
|
//=> search: '?fizz=buzz',
|
|
//=> query: {
|
|
//=> fizz: 'buzz'
|
|
//=> },
|
|
//=> }
|
|
|
|
// Attaches result for future memoization
|
|
assert.deepEqual(output, req._parsedUrl); //=> true
|
|
```
|

## API
|
|
|
|
### url(req)
|
|
Returns: `Object` or `undefined`
|
|
|
|
> **Important:** The `req` must have a `url` key, otherwise `undefined` will be returned.<br>If no input is provided at all, a `TypeError` will be thrown.
|
|
|
|
#### req
|
|
Type: `IncomingMessage` or `{ url: string }`
|
|
|
|
The incoming HTTP request (`req`) or a plain `Object` with a `url` key.
|
|
|
|
> **Note:** In Node.js servers, the [`req.url`](https://nodejs.org/api/http.html#http_message_url) begins with a pathname & does not include a `hash`.
