reactor VS Preact

I'd love to see this approach make more headway in the Django community. Based on the last DjangoCon it seems like the community is coalescing around HTMX.

This tool does play very nicely with Django's templating engine; you can just have HTMX re-render a particular template block on the server, and send down that updated block. The migration path is quite clean; you just wrap your "HTMX-updated" template block in a `hx-post` div.

Having not gone too deep on HTMX, I'm interested in folks' thoughts on where it's lacking vs. LiveView and Hotwire. One area I can see is performance; Elixir is going to be faster than Django, and so if you're trying to handle high session counts over websockets. But the impression I get is that HTMX is a bit more light-weight, so I'm wondering if there's usecases that can't be met with it vs. LiveView.

Other Django libraries that haven't quite seen as much uptake:

We have https://github.com/edelvalle/reactor, and a port of Hotwire: https://github.com/hotwire-django but both of these don't seem to have much adoption (yet!).

Thank you for posting those, I wanted to post them but I don't comment often (). Wanted to chip in another contemporary: edelvalle/reactor, which is inspired by LiveView[0].

I am using Hotwire for a project, and I'm learning Elixir and Phoenix on the side. Finding edelvalle/reactor was immediately helpful to me though, because I cut my teeth on Python/Django, so reading a Python reference implementation helps me learn nuts and bolts of libraries, faster. (so, I figure that this might help someone else grok how these approaches work.)

If this sounds like a barebones version of notable frameworks like Elixir's Phoenix LiveView, Rails's StimulusReflex or Hotwire Turbo, PHP's LiveWire, Django's Reactor... well, you're right! (Bonus: my colleague @jgaskins built a LiveView clone for Crystal)

Reactor

Reactor is a LiveView library for Django. It enables you to do something similar to Phoenix LiveView using Django Channels.

It looks a bit similar to Elixir Live View. Or similar in Django https://github.com/edelvalle/reactor, there are a couple of libraries.

Django does: https://github.com/edelvalle/reactor

In this post, we get to know more about Preact, one of this year's trending libraries. And we'll compare it to React to see which one suits better for our projects.

Similarly to Promises/A+, this effort focuses on aligning the JavaScript ecosystem. If this alignment is successful, then a standard could emerge, based on that experience. Several framework authors are collaborating here on a common model which could back their reactivity core. The current draft is based on design input from the authors/maintainers of Angular, Bubble, Ember, FAST, MobX, Preact, Qwik, RxJS, Solid, Starbeam, Svelte, Vue, Wiz, and more…

Those who want to develop a library that can be used by any other reactive framework. I often see SignalLike type that tries to subtype it.

The official Preact documentation.

At the very bottom of the image, there are 3 blocks that I chose to call application components. If you are building a cross-framework library, these can be built with whatever tools you want! Only catch is, all the tools you use to build it, will be needed by everyone consuming it. So choose wisely, and be mindful of how many kilobytes of third party code you will need in order to ship. In Schedule-X, I chose to use Preact. You will probably be fine with most lightweight virtual DOM libraries, and just like with frameworks there are a few to pick from.

React API reference > Components > Profiler:

DEV is a Rails monolith, which uses Preact in the front-end using islands architecture. The reason why I mention all this is that it's not a full-stack JavaScript application, and there is no state management library like Redux or Zustand in use. The data store, for the most part on the front end, is all data attributes.
