Can't get Rails 7 turbo_stream_from to update view from broadcast
The install notes here link to an issue specific to webpacker. Try that and see if it works?
-
Strong reasons to pick htmx, over hotwire?
True, in theory it is. A lot of it is coded in libraries like turbo-rails, though. And these are Rails-specific. But I've seen it being used in some Laravel projects, also I used it with Hanami.

Rails 7 - Turbo Frame and Turbo Stream
Check out https://github.com/hotwired/turbo-rails/blob/main/app/models/turbo/streams/tag_builder.rb

Use turbo_streams to update the client in real time from inside a loop?
So apart from the pretty obvious question of "why on earth would you want to do this?", I think there's a misunderstanding here of the intended use case of turbo streams. You have a page, and then some state changes on the server and you want to update the page to reflect that. Incrementing a variable doesn't really qualify as a state change, but perhaps a Product changing from "not good" to "good" would be an event worth broadcasting, which you could do using the Broadcastable concern in turbo-rails.

Using ViewComponents with Turbo
Not mentioned in the article, but it's nice that turbo-rails recently gained the ability to pass ViewComponent objects directly to turbo stream helpers. https://github.com/hotwired/turbo-rails/pull/433

Lazy loading of images in masonry layout?
You should only create the images (or set the src) for the images which are visible to the user. See our infinite scroll example for a naive implementation. More elaborated code might use the https://www.w3.org/TR/intersection-observer/.
