How to use View Transitions in Hotwire Turbo
So let’s add the following CSS to the index template (Slim recognizes a css: block that just renders a normal tag):
/ app/views/counter/index.html.slim / (anywhere outside the Turbo Frame tag) css: /* (1) */ #counter { view-transition-name: counter; contain: layout; } /* (2) */ @keyframes rotate-out { to { transform: rotate(90deg); } } @keyframes rotate-in { from { transform: rotate(-90deg); } } /* (3) */ ::view-transition-old(counter) { animation-duration: 200ms; animation-name: -ua-view-transition-fade-out, rotate-out; } ::view-transition-new(counter) { animation-duration: 200ms; animation-name: -ua-view-transition-fade-in, rotate-in; }
Enter fullscreen mode Exit fullscreen modeLet’s break this code down a bit:
-
The CSS selector
#counter
matches the counter div and theview-transition-name
property names this area of the screen, for the purpose of View Transitions, ascounter
. This name will be used in the animation declarations below.The
clone
property currently must be added here for some reasons internal to the current View Transitions implementation in Chrome and must be set topaint
orlayout
. This restriction is planned to be removed from the specification, though, and in fact I’ve heard that it is not needed in Chrome Canary any more. The rotation animation keyframes are defined here. Note that while the transition also uses fade-in and fade-out animations, they don’t have to be defined here because the spec requires browsers to implement them natively under the name
-ua-view-transition-fade-in/out
.The CSS animations for the counter (the View Transition area named
counter
) are configured here. The CSS selectors here are some of the pseudo-elements automatically created during the transition. The-old
pseudo-element represents a screenshot of the old DOM state that should somehow disappear or ”go away“ from the viewport and the-new
pseudo-element represents a live version of the final DOM state that should be brought into sight.
So, overall, this code selects a portion of the page and animates it independently from the rest of the page during Turbo Frames DOM updates. Behind the scenes, the default cross-fade for the rest of the page still also takes place, it just is not visible because all its elements are visually identical. The result looks like this:
A few initial tips & tricks
Does this work for Turbo Drive visits, too?
Sure it does and it’s actually pretty easy! All we have to do is define the same event handler as we did above but attach it to the
turbo:before-render
event instead. By default we’ll get a cross-fade animation of the whole page during Turbo Drive page visits.Do not try to ”name“ the Turbo Frame itself
When playing with Turbo Frame View Transitions I first tried to use a custom animation for the whole Turbo Frame element by naming it via the
view-transition-name
property. For some reason, this does not work and you end up with a very cryptic and misleading error message in the console (yes I did have thecontain
property in the CSS declaration):Aborting transition. Element must contain paint or layout for view-transition-name : counter
So, when using custom animations, an element from inside the Frame must be selected and named.
Debugging View Transitions
Since View Transitions are technically just normal CSS animations, they can be inspected with the Animations panel in the Dev Tools. Also, the automatically created pseudo-elements are visible in the Elements tab during the transitions:
Conclusions
I confess I am quite excited about the new View Transitions API. Among the things I particularly like about it are the following:
- It is surprisingly easy to plug this inside Hotwire Turbo and you get the default cross-fade transition animation immediately for free (in latest Chrome-like browsers, that is).
- Since this is implemented natively in the browser, the animations are highly optimized and performant.
- View Transitions should allow (today or in the future) building highly interactive transitions similar to those in Material Design.
- There is some initial support for Multi-Page Applications, too, which is great news because we can bring transition animations declared in CSS to our old but gold apps.
- It should be possible to use a different animation based on the ”direction“ of the visit (Back/Forward) using the Navigation API (also still experimental and not very well supported, though).
Things I am still concerned about:
- Browser support: the Firefox team evaluates it, the Safari team is silent. This will be a log run and making a polyfill is probably too difficult. For web sites where transition animations are critical, this is still a no go.
-
If you’re not careful enough, the transition feels more fluid but also a little bit slower. The reason for it is that View Transitions start the animations at the moment when both the old and new DOM states are already rendered. This means that the exit animation is delayed until new content is available and until that time, nothing happens. Also, the entry animations for the new state usually delay its appearance a little bit more.
This is not a problem of View Transitions themselves but rather a more generic one. If the exit animation (e.g. a fade out) started immediately after user interaction (e.g. a link click), sometimes the user would have to stare at a blank page until the new page content is grabbed, rendered and run through an entry animation. Still, some kind of support for this scenario (possibly with custom loaders or skeletons) would be nice.
Tailwind support: I think the current Tailwind syntax does not allow targeting the HTML document-connected pseudo-elements so we have to resort to custom CSS (which is not a big problem, actually).
All transitions target the whole page, there is currently no option to make, say, two components (Frames) animate totally independently. An initial proposal for ”scoped transitions“ can be found here.
Overall, I like this feature and wish it matures enough and gets wider support soon!

HTML is all you need to make a website
true, but HTML-only websites are often pretty clunky
infuriatingly, if HTML had just a bit more oomph, we could make a lot better websites with it, but they haven't been moving HTML forward as a hypermedia for decades now (see https://htmx.org for what I mean, they could implement this concept in the browser in a week, and it would change web development dramatically)
the upcoming view transitions API will help:
https://github.com/WICG/view-transitions
but, still, there are some really obvious and simple things that could be done to make HTML much more compelling (let's start by making PUT, PATCH and DELETE available in HTML!)

Can you achieve the same behaviour with JS?
Cool answer: Look at shared element transition. this is gonna be really cool one day, sadly not yet out of the proposal state... https://github.com/WICG/shared-element-transitions

Native features faster: Quickest path to utilizing native features/UX improvements once they are released, no need to wait for a third party implementation. Example: shared element transitions first came to native, then were replicated on the web.

Assorted Svelte demos: conditional wrappers, page transitions, actions
I took the experimental page transition API (a.k.a. shared element transitions) for a test drive with SvelteKit, and the result was pretty slick. You’ll need Chrome Canary with the chrome://flags/#document-transition flag enabled if you want to try this one out yourself — the original tweet has a video if you don’t want to jump through those hoops. There’s a live demo and a GitHub repo if you want to see how it was accomplished.

Nuxt vs Next: Which JavaScript Framework Suits Your Next Project?
According to Node Package Manager (NPM), Next.js has about 3.9 million weekly downloads while Nuxt.js has about 438,000. Although Next.js has a significantly higher number of weekly downloads, Nuxt.js still has a robust number of users. We can conclude that both frameworks are relevant and will stand the test of time.
-
Is Nuxt gonna change its pages dir?
Nuxt team themselves pointed that out [in first release](https://www.npmjs.com/package/nuxt/v/0.0.1) as well as you can see that statement in [Nuxt's wikipedia article](https://cdn.domin.pro/K2Qa). I completely agree with how Nuxt is better for an amount of features.

Will anyone hire a 33 yo newbie?
Node is basically back-end Javascript. While powerful alone, almost exclusively you will use a back-end framework like Next.js or Gatsby when using React, and then maybe Nuxt or Gridsome in Vue.

How to install Tailwind CSS with Nuxt.js and Flowbite
Nuxt.js is a free and open-source JavaScript framework based on Vue.js that helps you develop modern web applications using SSR (server-side rendering) which provides a faster load, better SEO (search engine optimization), and better caching capabilities.

Hosting your app for production – an overview
We made a LiveChat Next.js App template. Using Next.js as a foundation for the project, we have a front-end app with built-in routing, Server Side Rendering (SSR), and Server Side Generation (SSG) built with React, but on top of that, ready-to-use API routes built in the form of Serverless functions. If you prefer Vue.js or Svelte, you can choose similar frameworks, like Nuxt.js and SvelteKit.

Am I overthinking this?
Not oc, but maybe give Nuxt a look?
-
Resources similar to React's current beta docs, for other technologies in web development.
Vue's docs are some of the best I've ever read. Nuxt and Craft are pretty great too. I especially like how Craft's docs are bifurcated into the docs which give you the 20/80 + code snippets, and the class reference, which is complete documentation of every method, type, param, etc of the platform.
