webtransport VS stimulus_reflex

WebTransport is now enabled by default and will be going to release with 114. As the original Explainer notes, it enables multiple use-cases that are hard or impossible to handle without it, especially for Gaming and live streaming. It covers cases that are problematic for alternative mechanisms, such as WebSockets. Built on top of HTTP3 (HTTP2 support will be coming later). The current implementation in Firefox is passing 505 out of 565 Web-Platform Tests.

Sort of. The browser will re-use the connection if you have a bunch of resources in the HTML. When rendering it sees that it needs 2 images and 3 javascript files from the same server, so it pipelines all of those. But for requests initiated from javascript, you're going to get a new connection for each one unless you're using a library that implements the long-polling hack. SocketIO can use the long-polling hack as a fallback if websockets is not supported. HTTP/2 (formerly SPDY) gets part of the way to replacing websockets, but it's not a synchronous link. Only the client can send messages to the server and the server can only respond to those message (with websockets, either side can send messages once the connection is open). FWIW, less than 50% of websites use HTTP/2. HTTP/3's webtransport looks like it could replace websockets, but it also looks like it'll live along side websockets.

If it's streaming data like dashboard statistics the new WebTransport API might be a much better base: https://github.com/w3c/webtransport/blob/main/explainer.md

Are you guys looking into the Web Transport protocol for the future? Right now you have to tunnel the websocket connections over http2 and it will probably be the same for http3 afaik.

I know there is this work in progress (https://w3c.github.io/webtransport/) and websockets are probably fine for a long time but sooner or later (unless there is an update to websockets) it will probably be faster to just do normal http requests and listen on server sent events.

What are your thoughts for Liveview for the future? Will it forever stay on websockets or would you be open to change the underlying technology if / when new stuff becomes available?

It's taken nearly 10 years for QUIC to be refined and adopted in the wild and we're basically there. There's even a new browser API in the works called WebTransport.

tl;dr using WebRTC just for realtime client<->server data sucks, but WebTransport[1] is coming soon to serve that exact usecase with an easy API

WebRTC has data channels, which are currently the only way to achieve unreliable and unordered real-time communication (UDP-style) between the browser and other browsers or a server. This is pretty essential for any networked application where latency is critical, like voice and video and fast-paced multiplayer games.

As other commenters have noted, it's a royal pain in the ass to set up WebRTC if all you want is UDP-style communication between a server and browser, since you need to wrangle half a dozen other protocols in the process.

However! A new API, WebTransport[1], is actively being developed that will offer a WebSockets-like (read: super simple to set up) API for UDP-style communication. I am extremely excited about it and its potential for real-time browser-based multiplayer games (which I'm working on).

Then there are stack-specific libraries: StimulusReflex for Rails, Phoenix LiveView, Laravel Livewire, Unicorn and Tetra for Django, Blazor for .NET, … and the list goes on.

Morphing and the concept to do refreshes after broadcast are hardly new. Stimulus Reflex has employed morphing to update the page for years, and CableReady::Updatable, which allows listening to model requests for refreshes, has also been around for a while. But I am excited to see these concepts being adopted in Turbo and becoming more mainstream.

Stimulus Reflex (Ruby), which predates Hotwire, also deserves a mention, though most of its momentum seemed to stall when Hotwire was announced.

Hi there, not crazy experienced on the topic but after some research i made for personal reasons i found https://mayu.live/ whick looks interesting (and as mentioned already https://docs.stimulusreflex.com/, seems to be close to Liveview)

StimulusReflex Docs pretty easy to use and release 3.5.0 is coming soon.

However, the timing may be a little off. In some ways, it feels like the "Express" way of developing for the backend is dying. We are seeing tools that blur the line between backend and frontend, trying to unify how we develop web applications. Tools like Phoenix LiveView, StimulusReflex, Laravel Livewire, Remix, Next.js, and many others are being developed.

Reading the article and the source code, I learned a ton of stuff, as always. In his implementation, Louis is using StimulusReflex (built on top of Stimulus) to achieve this. I was curious about several points:

First things first: on the frontend, we’ll use StimulusReflex (a.k.a SR) to build a super reactive and friendly search experience with very little code, and little to no JavaScript. For those unfamiliar:

Now that we know that our backend is working as it should, let’s wire up our stuff. I’m gonna skip on Stimulus Reflex setup and configuration and dive right in. You can easily follow the official setup or, if you use import-maps, follow @julianrubisch’s article on the topic. I also know that leastbad has been working on an automatic installer that detects your configuration and sets everything up for you if you care to try it before the next version of SR gets released.
