README

Routing alias enhancer via middleware for TYPO3 CMS. Generates and resolves short URLs for pages and plugin records using configurable patterns.

Requirements

PHP ^8.2
TYPO3 ^13.4

Dependencies

brannow/typed-pattern-engine ^0.4 - AST-based pattern matching engine

Installation

composer require cpsit/shortnr

The extension auto-registers its middleware and cache configuration.

Configuration

Default Configuration

The extension ships with a minimal default configuration in Configuration/config.yaml:

shortNr:
  _default:
    notFound: "/"
    languageParentField: "l10n_parent"
    languageField: "sys_language_uid"
    identifierField: "uid"

  pages:
    type: page
    table: pages
    pattern: "p{uid:int(min=1)}(-{sys_language_uid:int(min=0,default=0)})"

Pattern Syntax

Patterns use the typed-pattern-engine syntax:

Syntax	Description
`{field:int(min=1)}`	Integer with minimum value
`{field:int(min=0,default=0)}`	Integer with default
`(-{field})`	Optional segment (parentheses)
`PREFIX{field}`	Static prefix

Example: NEWS{uid:int(min=1)}(-{sys_language_uid:int(min=0,default=0)}) generates NEWS123 or NEWS123-1

Adding Custom Configuration

Create an event listener to register your configuration file:

<?php
namespace Vendor\SitePackage\EventListener\ShortNr;

use CPSIT\ShortNr\Event\ShortNrConfigPathEvent;
use TYPO3\CMS\Core\Attribute\AsEventListener;

#[AsEventListener(
    identifier: 'site-package/shortNrConfigListener',
    event: ShortNrConfigPathEvent::class,
    method: 'loadConfig'
)]
class ConfigLoadingEventListener
{
    public function loadConfig(ShortNrConfigPathEvent $event): void
    {
        $event->addConfigPath('EXT:site_package/Configuration/cps_shortnr.yaml');
    }
}

Config Merging Behavior

Configs are merged via array_replace_recursive - higher priority configs (default: 10) override lower ones (extension default: -1000).

Every field can be overwritten by later configs
Arrays merge recursively (add new keys, override existing)
Set a field to null to remove it
the priority can be altered at the ShortNrConfigPathEvent::addConfigPath call

Configuration Examples

Page type:

shortNr:
  pages:
    type: page
    table: pages
    pattern: "PAGE{uid:int(min=1)}(-{sys_language_uid:int(min=0,default=0)})"

Plugin type (e.g., News):

shortNr:
  news:
    type: plugin
    table: tx_news_domain_model_news
    pattern: "NEWS{uid:int(min=1)}(-{sys_language_uid:int(min=0,default=0)})"
    plugin:
      extension: News
      plugin: Pi1
      pid: 43           # Page UID containing the plugin
      action: detail
      controller: News
      objectName: news  # Request parameter name

With conditions:

shortNr:
  event:
    type: plugin
    table: tx_news_domain_model_news
    pattern: "EVENT{uid:int(min=1)}(-{sys_language_uid:int(min=0,default=0)})"
    plugin:
      extension: News
      plugin: Pi1
      pid: 474
      action: detail
      controller: News
      objectName: news
    condition:
      is_event: 1

Available Condition Operators

See Configuration/config.example.full.yaml for detailed examples.

Operator	Example	Description
implicit	`field: value`	Equals
`eq`	`field: {eq: value}`	Equals (explicit)
`in`	`field: [a, b, c]`	Value in array
`contains`	`field: {contains: "text"}`	Substring match
`starts`	`field: {starts: "prefix"}`	Starts with
`ends`	`field: {ends: "suffix"}`	Ends with
`gt`, `gte`	`field: {gte: 50}`	Greater than (or equal)
`lt`, `lte`	`field: {lt: 100}`	Less than (or equal)
`between`	`field: {between: [10, 50]}`	Range
`isset`	`field: {isset: true}`	Field exists
`not`	`field: {not: {eq: value}}`	Negation

Usage

ViewHelper

Generate short URLs in Fluid templates:

<html xmlns:sn="http://typo3.org/ns/CPSIT/ShortNr/ViewHelpers"
      data-namespace-typo3-fluid="true">

<!-- By config name and UID -->
<sn:shortUrl name="news" uid="123" output="result" absolute="1">
    <f:if condition="{result.uri}">
        <a href="{result.uri}">{result.uri}</a>
    </f:if>
</sn:shortUrl>

<!-- From current page context (no name/uid = environment demand) -->
<sn:shortUrl output="shortNr" absolute="1">
    {shortNr.uri}
</sn:shortUrl>

<!-- From domain object -->
<sn:shortUrl object="{newsItem}" output="result" absolute="1">
    {result.uri}
</sn:shortUrl>

ViewHelper Arguments:

Argument	Type	Description
`output`	string	Variable name for result (required)
`languageUid`	int	Target language
`absolute`	bool	Generate absolute URL

The ViewHelper supports three demand modes (mutually exclusive):

Mode	Arguments	Description
Config + UID	`name` + `uid`	Explicit config name and record UID
Object	`object`	Domain object (extracts config + UID automatically)
Environment	(none)	Uses current page/plugin context

Service (PHP)

Encoding (generate short URL):

use CPSIT\ShortNr\Service\EncoderService;
use CPSIT\ShortNr\Service\Url\Demand\Encode\ConfigNameEncoderDemand;
use CPSIT\ShortNr\Service\Url\Demand\Encode\ObjectEncoderDemand;
use CPSIT\ShortNr\Service\Url\Demand\Encode\EnvironmentEncoderDemand;

// Inject EncoderService via constructor
public function __construct(private readonly EncoderService $encoderService) {}

// 1. Config + UID: Explicit config name and record UID
$demand = (new ConfigNameEncoderDemand('news', 123))
    ->setRequest($request)      // Required for site context
    ->setLanguageId(0)          // Target language (null = from request)
    ->setAbsolute(true);        // Full URL vs relative path
$uri = $this->encoderService->encode($demand);

// 2. Object: From domain object (AbstractEntity)
$demand = (new ObjectEncoderDemand($newsEntity))
    ->setRequest($request)
    ->setAbsolute(true);
$uri = $this->encoderService->encode($demand);

// 3. Environment: From current request context
$demand = (new EnvironmentEncoderDemand(
    $request->getQueryParams(),
    $request->getAttribute('frontend.page.information')?->getPageRecord() ?? [],
    $request->getAttribute('routing'),
    $request->getAttribute('extbase')
))
    ->setRequest($request)
    ->setAbsolute(true);
$uri = $this->encoderService->encode($demand);

Decoding (resolve short URL):

use CPSIT\ShortNr\Service\DecoderService;
use CPSIT\ShortNr\Service\Url\Demand\Decode\DecoderDemand;

// Inject DecoderService via constructor
public function __construct(private readonly DecoderService $decoderService) {}

// Direct: From short URL string
$demand = new DecoderDemand('NEWS123');
$fullUri = $this->decoderService->decode($demand);

// From request: Extracts short URL from request path
$demand = $this->decoderService->getDecoderDemandFromRequest($request);
$fullUri = $demand ? $this->decoderService->decode($demand) : null;

How It Works

Middleware intercepts GET requests and checks for short URL patterns
DecoderService matches request path against configured patterns
On match: 301 redirect to resolved full URL
On no match: request continues to TYPO3 routing

Encoding compiles record data into short URL using configured pattern. Decoding extracts UID from short URL, queries database with conditions, generates full URL.

Caching

Compiled patterns cached to filesystem
Encoded/decoded URLs cached with 1 week TTL
Cache cleared on cache:all or cache:pages flush
Cache tags: all, uri, encode, decode

NotFound Handling

Configure fallback behavior when a short URL cannot be resolved:

shortNr:
  _default:
    notFound: 2           # Page UID
    # or
    notFound: "/404"      # URI string
    # or
    notFound: ""          # Disable (continue to TYPO3 routing)

Extension Setup

The extension registers:

PSR-15 middleware (early in stack, before site resolution)
TYPO3 cache configuration (cps_shortnr)
DataHandler hook for cache invalidation
