Quick Start

Basic Usage with Redis

<?php

use Nimp\LinkLoom\UrlShortenerBuilder;
use Redis;

$redis = new Redis();
$redis->connect('127.0.0.1', 6379);

$shortener = (new UrlShortenerBuilder())
    ->withRedisRepository($redis)
    ->build();

// Shorten URL
$code = $shortener->encode('https://example.com/long-url');
echo "Short code: " . $code;

// Expand URL
$url = $shortener->decode($code);
echo "Original URL: " . $url;

With Logging

$shortener = (new UrlShortenerBuilder())
    ->withRedisRepository($redis)
    ->withLogger('/path/to/urls.log')
    ->build();

Advanced Configuration

$shortener = (new UrlShortenerBuilder())
    ->withCustomRepository(new MySQLRepository())
    ->withCodeGenerator(new MyCustomCodeGenerator())
    ->withCustomValidator(new MyCustomValidator())
    ->build();

Multiple Event Listeners

$shortener = (new UrlShortenerBuilder())
    ->withRedisRepository($redis)
    ->withLogger('/path/to/urls.log')
    ->addListener(new AnalyticsListener())
    ->addListener(new CacheListener())
    ->build();

Custom Event Dispatcher

$shortener = (new UrlShortenerBuilder())
    ->withRedisRepository($redis)
    ->withEventDispatcher($myCustomDispatcher)
    ->build();

Event System

LinkLoom provides a comprehensive event system for monitoring the URL shortening lifecycle using the Observer pattern.

Available Events

All events extend BaseShortenerEvent and provide access to the UrlShortener instance:

$event->context; // UrlShortener instance

Event	Trigger	Data
EncodeStartEvent	Before URL encoding starts	url, context
EncodeSuccessEvent	After successful URL encoding	url, code, context
DecodeStartEvent	Before code decoding starts	code , context
DecodeSuccessEvent	After successful code decoding	code, url, context
ValidateErrorEvent	When URL validation fails	url, message, context
GetFromStorageErrorEvent	When storage read fails	code, message, context
SaveErrorEvent	When storage save fails	message, context
