morphdom VS stimulus_reflex

morphdom

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.

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.

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!

using HTML-diffing libraries like morphdom to efficiently update elements on the page

no it actually looks like morphdom is what i'm looking for.

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.

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.

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.

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.

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.

You can also learn Rails and StimulusReflex

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:

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.
