YOURLS: Your Own URL Shortener

➤

About YOURLS

➤

What is YOURLS

YOURLS stands for Your Own URL Shortener. It is a small set of PHP scripts that will allow you to run your own URL shortening service (a la TinyURL or Bitly).

Running your own URL shortener is fun, geeky and useful: you own your data and don't depend on third-party services. It's also a great way to add branding to your short URLs, instead of using the same public URL shortener everyone uses.

➤

YOURLS Features

• Free and open-source software,
• Private (your links only) or Public (everybody can create short links, fine for an intranet),
• Terrific Plugin architecture and dozens of plugins to easily implement new features,
• Handy bookmarklets to easily shorten and share links,
• Awesome stats: historical click reports, referrers tracking, visitors geo-location,
• Developer API to integrate YOURLS into other applications,
• Friendly installer,
• Sample files to create your own public interface and more !

➤

Advanced settings

• You can install YOURLS behind a firewall or a proxy: see Proxy Support
• File includes/Config/Config.php contains a few more undocumented but self explanatory and commented settings. Add them to your own config.php if you know what you're doing.

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 and you can easily activate and deactivate a plugin from the admin interface.

There's a growing number of plugins available: check the Plugin list.

➤

Documentation

Several sample plugins are included in the archive. Read the source and learn the concept. It's easy and fun!

You need to send parameters to http://your-own-domain-here.com/yourls-api.php either via GET or POST (remember to URL-encode parameters if via GET). 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), "stats" (get stats about your links) or "db-stats" (get global link and click count)
• With action = "shorturl" :
  • the url to shorten
  • optional keyword and title for custom short URLs
  • output format: either "jsonp", "json", "xml" or "simple"
• With action = "expand" :
  • the shorturl to expand (can be either 'abc' or 'http://site/abc')
  • output format: either "jsonp", "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 "jsonp", "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 "jsonp", "json" or "xml"
• With action = "db-stats" :
  • output format: either "jsonp", "json" or "xml"

Sample requests

Example of a GET request with Javascript (using jQuery) to shorten a URL

var api_url  = 'http://sho.rt/yourls-api.php';
var response = $.get( api_url, {
    username: "your_username",
    password: "your_password",
    action:   "shorturl",
    format:   "json",
    url:      "http://ozh.org/"
    },
    // callback function that will deal with the server response
    function( data) {
        // now do something with the data, for instance show new short URL:
        alert(data.shorturl);
    }
);

Example of a POST request with PHP to expand a short URL

<?php
$username = 'your_username';
$password = 'your_password';
$api_url =  'http://sho.rt/yourls-api.php';

// Init the CURL session
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $api_url);
curl_setopt($ch, CURLOPT_HEADER, 0);            // No header in the result
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); // Return, do not echo result
curl_setopt($ch, CURLOPT_POST, 1);              // This is a POST request
curl_setopt($ch, CURLOPT_POSTFIELDS, array(     // Data to POST
        'shorturl' => 'ozh',
        'format'   => 'json',
        'action'   => 'expand',
        'username' => $username,
        'password' => $password
    ));

// Fetch and return content
$data = curl_exec($ch);
curl_close($ch);

// Do something with the result. Here, we echo the long URL
$data = json_decode( $data );
echo $data->longurl;

FAQ

➤

Server requirements and recommendations

1. We recommend PHP 7.4 or above
2. You will need at least MYSQL 5
3. A web server with mod_rewrite enabled
   Note: YOURLS can also run on Nginx, IIS and Cherokee
4. HTTPS support
5. PHP CURL extension installed if you plan on playing with the API

➤

Limitations

• Maximum length of custom keyword is 100 characters
• That makes several septillions of quinquagintillion of possible short URLs (seriously. That's a 180-digit number).

➤

Difference Between Base 36 And Base 62 Encoding

• Base 36 encoding uses 0123456789abcdefghijklmnopqrstuvwxyz for short URLs
• 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 if you're not sure.

➤

Getting a short domain name for your YOURLS install

• Unless you plan on making it public and as popular as bit.ly, any shared hosting will be fine. Ozh runs all his YOURLS instance on Dreamhost and it works just great.
• 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 need to handle URLs differently and need their own .htaccess file.
• 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
• Make sure your .htaccess file looks like this one
• Check that your server Apache configuration allows use of .htaccess (AllowOverride All directive, ask your server admin)
• Eventually, refer to Troubleshooting first steps.

➤

Random versus sequential short URLs

• Out of the box, YOURLS generates sequential short URLS (ie ab31, then ab32 and so on)
• If you prefer random short URLs (ie j3kz1 then 13hz7 like Bitly does), just activate the plugin that comes with YOURLS.

➤

"Stats don't update as I think they should", "difference with Google Analytics", etc...

• Out of the box, YOURLS updates traffic stats every time a short URL is requested. Period.
• This said, some clients (like indexing bots, your internet browser) may skip requesting a short URL if they have the final destination known in cache.
• Conversely, other stat tools may use different techniques to track hits (using javascript or not, using IP address, filtering multiple requests by same client, etc...)
• Bottom line: your mileage may vary with different tools, but there is no bug in YOURLS regarding that matter.

➤

There is no index page at the root of the install

• Indeed. It's intended. It's up to the user to make what they need. Some will redirect the root to a different place, some make a public interface for anyone to shorten links, some make a portfolio. You make it. See Awesome YOURLS for inspiration!
• If you want to make a public interface and run your own little bitly.com, there's a sample file provided as an example: sample-public-front-page.txt. This implies important issues to deal with: spam, performance and security. Read Public Shortening for important information.

➤

Uppercase letters in short URLs are eaten up, eg "OmgOzh" becomes "mgzh" !

• Indeed. It's intended if you selected Base 36 (see above). Letters that don't belong to the character set, eg @#! or ABC, are removed.
• If you want to force lowercase, you'll need a plugin.
