swup VS htmx

https://swup.js.org/ single-page-app but with minimal framework, still along for the feel of an SPA

Sure, you can use any number of JS-avoidance libraries. I'm a fan of Turbo, and there's also htmx, Unpoly, Alpine, hyperscript, swup, barba.js, and probably others.

Swup is this nice page transition library I found recently : https://swup.js.org/

2. The newly released fragment-plugin [3] that provides a declarative API for dynamically replacing containers based on rules

I can now finally build websites that tick all three boxes:

1. Visually impressive, fun, and snappy by using swup's first-class support for animations[4], cache[5], and preload capacities[6], enhanced with fragment visits as seen on the demo site.

2. Accessible by being able to serve server-rendered semantic markup that will fully work even with JavaScript disabled (try it out on the demo site!). On top of that, swup's a11y plugin[7] will automatically announce page visits to assistive technologies and will focus the new `

` element after each visit.

3. Because now all I need for my fancy frontend is a bit of progressive JavaScript, I can choose whatever tool I like on the server, keeping complexity low and maintainability high. I can use SSGs like eleventy or Astro (the demo site is built using Astro!), I can use any CMS like WordPress or ProcessWire, or a framework like Laravel. And I don't have to maintain an additional node server for SSG!

And all it took was 20 years! ;)

So what are View Transitions good for? In short, they allow adding animated page transitions. Although we already have several standard options to animate stuff on web pages (CSS Transitions, CSS Animations or the Web Animations API) and countless more options in particular JavaScript frameworks and libraries (Framer Motion for React, Vue Transitions, Svelte Transitions, Swup, Barba.js or Animate.css to name just a few), the web still lacks a generic, standards-based and easy-to-use solution to animate transitions between pages or during DOM updates. At least that’s what Google engineers say and I tend to agree with them.

Is https://turbo.hotwired.dev/ my replacement? Or Swup.js?

I've used https://swup.js.org/. Simple to setup with one of the built in/contributed themes, haven't tried building a custom theme however. Also has a lot of good plugins for eg. accessibility. I used it in combination with Astro so a static site with a separate html file for each page.

Like Gatsby or Next, Astro does not have any client side navigation. So each link click triggers a full page reload. Astro recommends to use Swup as mentioned here. Turbo is also another option though the team does not recommend it. I'm currently using Swup which I'll probably switch from or completely remove it as I have added TOC to MDX and clicking on a title is not redirecting the page to that particular section.

When I work with HTMX I need isolated component that can be reusable a form. So I create a PHP Function that generate the Input Datalist.

I was inspired by htmz (which was in turn inspired by htmx) and how the author got pretty close to a basic htmx-like experience just using an iframe. I wanted to push it a little further so whipped this demo together. My submission demonstrates progressive enhancement for the form - with js enabled the request targets an iframe that is inserted into the dom, meaning the page doesn't actually navigate (similar to event.preventDefault()). The iframe receives the html response from the request and on load triggers a function to swap out it's contents into the main page.

As described on htmx.org: "htmx gives you access to 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"

Apart from the source code itself, the repo's README also gives a bit more details about the various packages I used.

1. htmx: https://htmx.org/

Also, there’s some response header juggling you have to do when submitting forms that have a validation step before redirecting: https://github.com/bigskysoftware/htmx/issues/369

I’ve tried to iron out any footguns or server requirements I’ve bumped into while using HTMX & Hotwire in my projects.

✨ In recent months, I have been developing web projects using GOTTHA stack: Go + Templ + Tailwind CSS + htmx + Alpine.js. As soon as I'm ready to talk about all the subtleties and pitfalls, I'll post it on my social networks.

I've been digging into HTMX lately (using Python web frameworks) and find the concepts and approach to be interesting and promising. The idea of hypermedia driven systems over the current practice of JavaScript based frameworks (I never really got into React, played with Vue, and enjoy Svelte/SvelteKit) and the ability to chose your language/framework for the backend while primarily leveraging HTML/CSS on the frontend just seems refreshing.

Apparently it changed from 2-clause BSD: https://github.com/bigskysoftware/htmx/commit/e16f1865a494b6...

(The zero clause license drops the requirements for preserving the copyright notice when distributing)

It would be a sin not to start with something that prides itself on being the front-end library of peace. HTMX skyrocketed in popularity in 2023, gaining most of its GitHub stars during the past year. HTMX is not your average JS framework. If you work in HTMX, you will spend most of your time in the world of hypermedia, looking at web development from a completely different pair of eyes as compared to our usual JS-heavy outlook on modern web development. HTMX leverages the power of the concept of HATEOAS (Hypermedia as the Engine of Application State), enabling developers to access browser features directly from HTML, instead of using Javascript.
