@polka/url

Super fast, memoized req.url parser; not limited to Polka!

Parses the url from a 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.
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

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

If no input is provided at all, a TypeError will be thrown.
