A simple library that can unshorten any short url.
npm install unshortener
or
git clone https://github.com/Swizec/node-unshortener.git
cd node-unshortener
npm link
// expand an URL
var unshortener = require('unshortener');
// you can pass in a url object or string
unshortener.expand('http://t.co/rWP6BP3',
function (url) {
// url is a url object
console.log(url);
});
If you have a handy bitly account you should also pass in an options object to enable the unshortener to use the bitly API directly:
// expand an URL
var unshortener = require('unshortener');
// you can pass in a url object or string
unshortener.expand('http://t.co/rWP6BP3',
{bitly: {username: '<YOUR BITLY USERNAME>',
apikey: '<YOUR BITLY API KEY>'}},
function (url) {
// url is a url object
console.log(url);
});
One final warning about bitly; as of this writing node-bitly as it sits in the npm repository is broken and you should install from git directly despite the fact both versions are 1.0.1.
node-unshortener aims to be able to unshorten any link possible, so it tries to behave as a browser and simply follows all the redirects. However, to be nice, when at all possible, it tries to use the url shortener's official API.
That said, please feel free to suggest any unshortening services I may have missed.
Services directly supported so far:
- bit.ly
- j.mp
- is.gd
- goo.gl
