Plugins for YOURLS

Plugins?

Plugins are additional PHP scripts that extend the functionalities or features of YOURLS. The core of YOURLS is designed to be as light as possible and avoid bloat (implementing functions not everybody needs) and to allow for easy customization.

Using the plugin architecture, you can add new features to YOURLS without having to modify core files. This way, your changes won't be lost when you upgrade your YOURLS installation.

Documentation

A sample plugin is included in the archive. Read the source and learn the concept. It's easy!

YOURLS' API

Features

• Generate or get existing short URLs, with sequential or custom keyword
• Get some statistics about your links: top clicked links, least clicked links, newest links
• Output format: JSON, XML, or simple raw text
• Authentify either with login/password or using a secure passwordless mechanism

Usage

You need to send parameters to http://yoursite.com/yourls-api.php either via GET or POST. These parameters are:

• A valid username / password pair, or your signature (see Passwordless API requests)
• The requested action: "shorturl" (get short URL for a link), "expand" (get long URL of a shorturl), "url-stats" (get stats about one short URL) or "stats" (get stats about your links)
• With action = "shorturl" :
  • the url to shorten
  • optional keyword for custom short URLs
  • output format: either "json", "xml" or "simple"
• With action = "expand" :
  • the shorturl to expand (can be either 'abc' or 'http://site/abc')
  • output format: either "json", "xml" or "simple"
• With action = "url-stats" :
  • the shorturl for which to get stats (can be either 'abc' or 'http://site/abc')
  • output format: either "json" or "xml"
• With action = "stats" :
  • the filter: either "top", "bottom" , "rand" or "last"
  • the limit (maximum number of links to return)
  • output format: either "json" or "xml"

	<shorturl>http://yoursite.com/shorter</shorturl>
</result>

Sample file

There's a sample file included that serves as an example on how to play with the API

FAQ

Server requirements

1. A server with mod_rewrite enabled
2. At least PHP 4.3
3. At least MYSQL 4.1
4. Note: YOURLS can also run on Nginx (Read more)

Server recommendations

• PHP CURL extension installed if you plan on playing with the API

Limitations

• Maximum length of long URLs to be shortened is 2000 characters
• Maximum length of custom keyword is 200 characters
• That makes about 8 sexdecillions of centillions of available URLs (seriously. That's a 355 digits number).

Difference Between Base 36 And Base 62 Encoding

• Base 36 encoding uses 0123456789abcdefghijklmnopqrstuvwxyz
• Base 62 encoding uses 0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz
• Stick to one setting, don't change after you've created links as it will change all your short URLs!
• Base 36 is the default and should be picked.

Getting a short domain name for your YOURLS install

• Unless you plan on making it public, any shared hosting should be fine
• Domainr is a fun search tool that might inspire and help you
• Aim for exotic top level domains (.in, .im, .li ...), they're often cheap and a lot are still available. Gandi is a pretty comprehensive registrar, for instance.

YOURLS needs its own .htaccess

• You cannot install YOURLS and, say, WordPress, in the same directory. Both of them need to handle URLs differently
• If you want to install YOURLS on the same domain than your blog, give it its own (short) subdirectory, such as yourblog.com/s/ (for "short") or yourblog.com/x/ (for "exit")

If YOURLS generates 404 for your short URLs

• Make sure mod_rewrite is enabled with your Apache server
• Some (crappy) hosts such as GoDaddy or 1and1 need a small fix to .htaccess
