Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

HTML Streaming and DOM Diffing Algorithm

The Ultimate Search for Rails - Episode 1
And sure enough, it works! So what's going on here? Well, clicking the link invokes our reflex, which gets executed right before our current controller action runs again. It allows us to execute any kind of server-side logic, as well as play with the DOM in various ways, but with ruby code. Then, the DOM gets morphed over the wire.

Build a JS Framework with 80 lines of Javascript
It's super simple actually. And that is in large part to (Morphdom)[https://github.com/patrick-steele-idem/morphdom] which I'm using to compare the output of render() to what is already on the DOM. Morphdom will patch the differences.

Using hotwired/turbo but patch the DOM vs Replacing
I'm using morphdom to patch our DOM. Its a very simple library that compares two DOM elements and updates only the differences. It is extremely performant and does not even use a Virtual DOM, just the DOM you already have!

how do i morph an entire html document dom?
no it actually looks like morphdom is what i'm looking for.

ssceng demo: Hacker News Client
It tries to morph into existing DOM (with https://github.com/patrick-steele-idem/morphdom). In case of fail, there is fallback to HTML replacement with outerHTML. All DOM operations after action occurs on component level, not the whole page.

Building a Live Search Experience with StimulusReflex and Ruby on Rails
Today, we’re going to build a live search experience once more. This time with StimulusReflex, a “new way to craft modern, reactive web interface with Ruby on Rails”. StimulusReflex relies on WebSockets to pass events from the browser to Rails, and back again, and uses morphdom to make efficient updates on the client-side.

Displaying Real-Time Data in Your Web Application Without Hassle: IHP Auto Refresh ✨
Whenever the JavaScript on the browser-side receives new HTML, it will update the current page using a DOM-diff approach (using morphdom). So only DOM nodes that have actually changed between the initial page load and the updated HTML will be updated.
-
Why Virtual DOM is considered faster that directly updating the real DOM.
Updating the DOM is not slow. In fact, there are libraries and frameworks that emphatically reject the virtual dom approach. morphdom is one such example of a DOM modification library. Svelte's author Rich Harris has been proclaiming for a while that virtual dom is an overhead (see e.g. this article). Google's lit-html and lit-element do much of what react does without the virtual dom.

Back-end languages are coming to the front-end
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!).

Reactive Clojure: You don't need a web framework, you need a web language
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].
[0]: https://github.com/edelvalle/reactor
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.)

How to combine Rails's Ajax support and Stimulus
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)
