Feature: #106405 - TypolinkBuilderInterface 

Description 

A new interface \TYPO3\CMS\Frontend\Typolink\TypolinkBuilderInterface has been introduced to provide a more flexible way to generate links in TYPO3.

The interface defines a buildLink() method that replaces the previous build() method approach when extending from \TYPO3\CMS\Frontend\Typolink\AbstractTypolinkBuilder .

All core TypolinkBuilder implementations now implement this interface and use dependency injection for better service composition and testability.

The interface method signature is:

public function buildLink(
    array $linkDetails,
    array $configuration,
    ServerRequestInterface $request,
    string $linkText = ''
): LinkResultInterface;

Impact 

• All implementations of TypolinkBuilderInterface are automatically configured as public services in the DI container, eliminating the need for manual service configuration.
• TypolinkBuilder classes can now use proper dependency injection through their constructors, making them more testable and following TYPO3's architectural patterns.
• The ServerRequestInterface is now passed directly, providing better access to request context without relying on global state.
• The new interface provides a cleaner separation of concerns and more explicit parameter passing.

Example usage 

Creating a custom TypolinkBuilder with the new interface:

use Psr\Http\Message\ServerRequestInterface;
use TYPO3\CMS\Frontend\Typolink\TypolinkBuilderInterface;

class MyCustomLinkBuilder implements TypolinkBuilderInterface
{
    public function __construct(
        private readonly MyCustomService $customService,
        private readonly AnotherService $anotherService,
    ) {}

    public function buildLink(
        array $linkDetails,
        array $configuration,
        ServerRequestInterface $request,
        string $linkText = ''
    ): LinkResultInterface {
        // Access ContentObjectRenderer from request
        $contentObjectRenderer = $request->getAttribute('currentContentObject');

        // Use injected services
        $processedData = $this->customService->process($linkDetails);

        // Build and return link result
        return new LinkResult($processedData['url'], $linkText);
    }
}

Registering the TypolinkBuilder class is still necessary via $GLOBALS['TYPO3_CONF_VARS'] .
