README

The WebLink component manages links between resources. It is particularly useful to advise clients to preload and prefetch documents through HTTP and HTTP/2 pushes.

This component implements the HTML5's Links, Preload and Resource Hints W3C's specifications. It can also be used with extensions defined in the HTML5 link type extensions wiki.

It also implements Web Linking (RFC 8288), the two link set document formats defined by Linkset (RFC 9264) and the Link-Template HTTP header field (RFC 9652).

Getting Started

composer require symfony/web-link

use Symfony\Component\WebLink\GenericLinkProvider;
use Symfony\Component\WebLink\HttpHeaderSerializer;
use Symfony\Component\WebLink\Link;

$linkProvider = (new GenericLinkProvider())
    ->withLink(new Link('preload', '/bootstrap.min.css'));

header('Link: '.(new HttpHeaderSerializer())->serialize($linkProvider->getLinks()));

echo 'Hello';
