WebSub cannot be used by browsers because browsers cannot receive POST requests. WebSub is for server to server communications. Mercure is basically WebSub over SSE. The draft has …

Yes, as it 's "just" SSE, this works pretty well behind Cloudflare and other similar solutions. Mercure also automatically sends the NGINX-specific headers required to allow unbuff…

Once the connection is upgraded, you loose all metadata included in the HTTP headers (because it’s not HTTP) and all protections relying on it. Also CORS and SOP can be bypassed: h…

This limitation is gone with HTTP/2 and HTTP/3 and the Mercure hub automatically use the most recent protocol supported by the browser.

Hi, Mercure author here. Indeed that's how it works. One of the key point of the solution is that you don't need anything client-side. The native EventSource class is all you need …

Hi, Mercure author here. WebSockets are hard to secure (they totally bypass CORS as well as other browser built-in protections), don't work (yet) with HTTP/3 and for most use cases…

SSE/Mercure (as WebSockets) is much battery-efficient than polling (push vs poll, less bandwidth used). Additionally, on controlled environnements, SSE can use a « push proxy » to …

A while ago I created Mercure: an open pub-sub protocol built on top of SSE that is a replacement for WebSockets-based solutions such as Pusher. Mercure is now used by hundreds of …

The Symfony framework (PHP) provides a similar feature, which also relies on LISTEN/NOTIFY and FOR UPDATE SKIP LOCKED: https://symfony.com/doc/current/messenger.html#doctrine-tran.…

That's not the case with other engines able to keep the booted app in memory to handle several requests (FPM doesn't support this).

This script is entirely optional and is only used to create static builds of FrankenPHP or to create self-executable PHP apps. It doesn't require a Docker image but does need some …

Optionally, you can embed the PHP scripts in the final binary using a Go feature similar to `include_bytes`: https://frankenphp.dev/docs/embed/ But for PHP, it's even simpler: PHP …

This means that in addition to any PSR-7 implementation, you can run apps using HttpFoundation (Symfony, Laravel, Drupal, etc) and "legacy" code using superglobals without the need…

Unlike Laravel and Symfony, WordPress doesn't support the worker mode of FrankenPHP (yet?), so there are not many benefits in terms of performance (except the ability to preload as…

Hi, FrankenPHP author here. We would very much appreciate a reproducer. According to most benchmarks, FrankenPHP is generally much faster (~3 times) than FPM when worker mode is en…

I maintain the Mercure protocol (built on SSE) and the reference implementation (written in Go, available as a standalone binary and a Caddy module) which does exactly that: https:…

I haven't tested it yet, but yes it's a stated goal.

Definitely! (using xcaddy and compiling PHP yourself, for now)

The approach isn't the same: Roadrunner executes php-cli and connects it to its web server through GRPC; FrankenPHP uses an ad-hoc SAPI, it is more like Apache's mod_php, the Go co…
