: ) Don't get me started on LiveView, i was only talking about mimicking rails mixins with the "use" macro in phoenix.

But now that you ask: The LiveView Idea to use websockets in general purpose web applications to achieve "reactivity" is an abomination, we have SSE and HTTP2 and also SPAs for that matter, which are from an operational and reasoning standpoint 1000% simpler and actually made for this kind of thing.

Websockets are for things like multiplayer shooters or collaborative drawing, why would someone think it is appropriate to use it to react to clicking a button.

So what should Phoenix use instead of a using macro to accomplish this?

SPAs are hugely complicated though. Have you worked on a production React app? It's another order of complexity above anything existing in BEAM world, and the JavaScript tooling ecosystem is atrocious in comparison. Not to mention, you will quickly end up having button clicks that require network requests if you are not careful with your SPAs as well.

The whole point of LiveView is that you can develop an app with a similar amount of interactivity as a React app without having to go into the split-universe world that SPAs live in and all the attendant complexity that brings with it.

People said JavaScript was just for making ad banners flash 20 years ago and now it's the most popular language on the planet. I don't think a technology's current uses are a good predictor of what it is most useful for. See also: the web itself becoming an application platform, while it started off as a hyperlinked document retrieval system.

With respect, web sockets are a tool. If you think it is inappropriate to use a tool a certain way then your are obviously free to feel that way, but it seems a little “get off my lawn” to be upset with other folks finding creative uses for it.

My team is using live view and accomplishing incredible things with far less time and effort than we would need using other SPA technologies.

I have no idea how you can assert SSE, HTTP2 and SPAs are 1000% simpler when my experience over the last two years has been the exact opposite. Live view is exceedingly simple to work with.
