urlparse-cache

Parse a url string using Node's builtin module and cache the results

Usage

var urlparse = require('urlparse-cache');
var parsed = urlparse('http://daveeddy.com/?page=index');
// => same object as require('url').parse(<url>)

var parsed2 = urlparse('http://daveeddy.com/?page=index'); // cache hit
// => same object as above

Benchmark

Parsing a URL 200,000 times with no cache using require('url').parse(uri, true)

$ time node benchmark/no-cache.js
Parsing "http://example.com/some/path?key=value&otherkey=othervalue#hash" for 200000 iterations (no cache)

real    0m6.997s
user    0m6.972s
sys     0m0.061s

Parsing a URL 200,000 times using this module to cache the result of require('url').parse(uri, true)

$ time node benchmark/with-cache.js
Parsing "http://example.com/some/path?key=value&otherkey=othervalue#hash" for 200000 iterations (no cache)

real    0m0.080s
user    0m0.068s
sys     0m0.011s

Notes

The cache has no method for clearing out old keys/values, as the url->object mapping will never change, ie. same url in, same url object out. This has the potential to get very large if you parse a lot of different urls.

Installation

npm install urlparse-cache
