    I created intercooler.js in 2013 so I could do AJAX in HTML:

    Last year I removed the jquery dependency and cleaned it up based on a lot of lessons that I learned, renaming it to hmtx:

    Same idea: extends/complete HTML as a hypertext so you can build more advanced UI within the original hypermedia web model, and cleaner implementation.

    Part of that cleanup involved me pulling out some functionality around events and a proto-scripting language (ic-action), and I enjoy programming languages, so I created a front end scripting language to fill that need:

    It's based on HyperTalk and has a lot of domain specific features for lightweight front end scripting, kind of a jQuery or AlpineJS alternative.

    This is my experience, and your mileage may vary:

    Multiple times in my coding career I have felt stalled and/or like I was regressing.

    Early on, I worked on a programming language, gosu ( which ended up not really going anywhere. Once the work on it was done, I returned to more mundane web programming for a while. A long while after that, and unexpectedly, I turned a jQuery function I was noodling on into intercooler.js ( After a year of that I returned to mundane web programming for quite a while. Unexpectedly, a year ago, the country shut down. I was at home and decided to see if I could remove the jQuery dependency in intercooler.js, and so created htmx ( When creating htmx and removing some attribute/functionality, I realized that a small programming language would be the ideal replacement, so I created hyperscript: I had not expected to work on a programming language again, but now I am.

    So my career has been some very exciting technical projects punctuating long stretches of pretty basic web development, where the most exciting thing is me wondering if I can figure out what the deuce is wrong with my CSS. My takeaway here, at least in my career, is that patience is a virtue, and the interesting stuff tends to come up at irregular intervals and in unexpected moments and ways.

    htmx is the successor to intercooler.js. It swaps parts of the page, not the whole page like Turbolinks. htmx allows you to access AJAX, CSS Transitions, WebSockets and Server Sent Events directly in HTML, using attributes, so you can build modern user interfaces with the simplicity and power of hypertext

  • 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.

    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.
    3 projects | | 10 Apr 2021
    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.

    Sockpuppet is a new way to craft modern, reactive web interfaces with Django. It extends the capabilities of both Django and Stimulus by intercepting user interactions and passing them to Django over real-time websockets. These interactions are processed by Reflex actions that change application state. The current page is quickly re-rendered and the changes are sent to the client. The page is then updated using a fast and lightweight DOM diffing/patching library called morphdom to reflect the new application state. This entire round-trip allows us to update the UI in 20-30ms without flicker or expensive page loads.

    also, StimulusReflex predates Hotwire for 1 year and is already pretty hardened :-)
