Simple Angular / PHP - Url Shortener

Before you begin

Origin

This is the public copy of the url shortener used for Hurz.Me / Fade.At Because of license Issues (I don't own the rights to copy the artwork used) and security issues some things have been removed:

Missing Contents

All Images have been removed. So you have to create your own Artwork if you want to have this fancy.

Database

Before you can begin, you have to create a Database and four Tables to store the data. The following Snippet creates those tables: Important If you decide to create the tables manually, make sure to use a collation for the "token" columns that are Case-Sensitive.

SQL-Creation-Script

CREATE TABLE `calculated` (
  `id` bigint(11) NOT NULL AUTO_INCREMENT,
  `target` varchar(1024) NOT NULL,
  `expire` datetime DEFAULT NULL,
  PRIMARY KEY (`id`),
  KEY `expire` (`expire`)
);

CREATE TABLE `calculatedaccess` (
  `id` bigint(20) NOT NULL,
  `accessdate` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
  KEY `idx_calc` (`id`)
);

CREATE TABLE `custom` (
  `id` bigint(20) NOT NULL AUTO_INCREMENT,
  `token` varchar(255) CHARACTER SET utf8 COLLATE utf8_bin NOT NULL,
  `target` varchar(1024) NOT NULL,
  `expire` datetime DEFAULT NULL,
  PRIMARY KEY (`id`),
  UNIQUE KEY `token` (`token`),
  KEY `expire` (`expire`),
  KEY `token_2` (`token`)
) ;

CREATE TABLE `customaccess` (
  `token` varchar(255) CHARACTER SET utf8 COLLATE utf8_bin NOT NULL,
  `accessdate` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
  KEY `idx_custom` (`token`)
) ;


ALTER TABLE `calculatedaccess`
  ADD CONSTRAINT `rts_calculated` FOREIGN KEY (`id`) REFERENCES `calculated` (`id`) ON DELETE CASCADE;

ALTER TABLE `customaccess`
  ADD CONSTRAINT `idx_custom` FOREIGN KEY (`token`) REFERENCES `custom` (`token`) ON DELETE CASCADE;

Some Explanation: In [custom] all custom tokens (5 characters or more) are saved, [calculated] stores all calculated redirects. The [*access] - tables store all external access to the url.

Configuration

Just add a "connect.php" into the php-folder containing the following contents:

<?php
function Connect() {
        $dbHost="localhost";
        $dbName="myDatabase";
        $dbUser="username";
        $dbPass="p@ssw0rd";

        return new PDO('mysql:host='.$dbHost.';dbname='.$dbName, $dbUser, $dbPass);
    }
?>

Watch the Project in Action

You can see what this project does on "http://fade.at",

Additional Stats

As you can see statistics for any address by adding "/stats" to it, you can also see statistics about all custom or all calculated redirects.

To see those just enter [yourdomain]/calculated/stats or [yourdomain]/custom/stats (It would possibly be a good idea to "block" those two custom domains by putting them into the "custom"-table without an expiry-date)

Spam protection

This project uses a very simple JavaScript-Based Spam-protection. It is based on the thoughts of [David Walsh] (https://davidwalsh.name/wordpress-comment-spam) (yes a popular journalist who does JavaScript. How awesome is that?) ;)

I used nearly the same technique on my wordpress-blogs and successfully blocked all spam. But be aware that while this is great to trick any Spam-bot, it can easily fail if someone decides to write a spam-mechanism especially for your site.
