New in Symfony 3.3: WebLink component
A few weeks ago, we added support for asset preloading with HTTP/2 Push. The feedback was so enthusiastic that we decided to improve and expand this feature. In fact, we decided to create a whole new component for it: WebLink.
This new component manages links between resources, not only assets; advising browsers to preload and prefetch resources through HTTP and HTTP/2 pushes. The component implements these specifications: HTML5 Links, Preload, and Resource Hints
All these new features can be used via several Twig functions:
link(), adds the
preload(), preload resources (not only assets);
dns_prefetch(), resolves a resource origin as early as possible;
preconnect(), initiates a early connection to a resource (including DNS resolution, TCP handshake, and TLS negotiation);
prefetch(), indicates to the client that it should prefetch the given resource;
prerender(), indicates to the client that it should prerender the given resource.
Unlike the previous preloading feature, this component is not only useful for web assets. Being a standalone component means that it can also be used for example to replace resource embedding by HTTP/2 pushes in your APIs.
