AnimeJs v4 Is Here

20 hours ago (animejs.com)

Scrolling through that landing page felt a lot smoother & snappier than I would've expected for a page looking like that.

  • Julian (the author) is a genius. v4 has been in the making for some time, but, boy, is it worth the wait! I have used v3 (I am using it on my landing page and even built a small game engine with it), but this version is on a whole new level. Congrats to the author! Keep up the good work!

    • > Julian (the author) is a genius.

      With proof!

      I have rarely been so impressed with a web tech.

  • yeah. i'm normally not a big fan of these scroll down and "shit-happens" sites, but that is VERY slick and cool. super nice.

  • I think part of the trick is that each unit of scrolling takes you quite far down the animation sequence (so scrolling doesn't feel like a long effort)

  • I don't even remember seeing such a fantastic landing page in long time. it makes you realise how bad others are.

  • It's clever, but honestly I don't care how smooth it is. Scrolling should simply scroll a view up or down a page. Not invoke animation. We already have established UX patterns for playing media, slowing it down, speeding it up, randomly seeking through it.

    • Part of the smoothness here is that scrolling the text is 1:1 once you get down to the sections with colored headers. It demonstrates that it's possible to make a page look fancy like that without "breaking" your intuition of what scrolling "should be."

      JS animations obviously don't take the place of video/audio media that you'd play/scrub through.

    • It's not so much about playing/slowing/speeding up an animation or video. It's about moving forward and backward through an "experience," as much as I dislike the overuse of that word. I'd suggest it's a natural evolution of the scroll behavior.

    • For most websites, sure. For this website? It makes sense, it's a great demo for the product.

Looks very nice!

Having said that: I severely hate content in this form, where you have to scroll like your life depends on it just to read a paragraph or two.

Probably a dumb question but.. Is the 3d exploding diagram model of the engine here just a visual metaphor for a complex system working in sync with itself? Or actually created using the toolkit? I flipped through the API and everything appears to be lower-level animation support, but intro gives the impression that it's CAD-like.

Wow, that homepage was one of the more complex and layer filled interactive animations that I ever seen running so smoothly on a mobile browser. Those FPS feel like a Doom 2016 on a beefy PC.

I cannot believe this is real, it was so well done. It felt like creativity of the internet from the early 2000s met the polished design standards of today.

This is the first time I haven’t hated scroll hijacking. That was actually really smooth.

I love it, but... Going to this page https://animejs.com/documentation/scope/ with ublock origin enabled in my Firefox (136.0.3) immediately crashes the tab. Which certainly made for a funny experience right after scrolling through the very impressive intro animation.

  • I can confirm. It's not a 100% occurrence, but browsing through that section ends up crashing the tab.

  • Ooh, fun, reproducible on Firefox for Android. Crash signature [@ JS::Heap<T>::exposeToActiveJS ].

I like that I can grab and drag the browser’s scroll indicator and the animation updates seamlessly (safari mobile).

  • It responds to the scrolling, leaving agency to the user, instead of hijacking scrolling, that steal agency from the user, that some web sites do. It's so much better of a solution and friendly to accessibility.

  • TIL you can grab the scroll bar on iOS!!

    Thanks for this. Jumping to the bottom of a page was such a chore for me.

I thought the main site was amazing, then I saw the docs. Absolutely amazing work. Well done. Extremely excited to try out WAAPI.

I can't speak to what it's like to actually work with this, but I really like the API design and docs. This feels really well thought out. Looking through the timer docs for example, it took just a minute or so to understand what the timer API can do and how to do it. This gives me a lot of confidence to try out the library.

As others have said, beautiful work on the lander. It looks and performs beautifully.

I was absolutely floored by the website, what a way to knock it out of the park.

I have never heard of this library before, but it’s going to stick in my head the next time I’m looking for a JS animation lib.

Definitely kinda highlights the importance of first impressions.

Ooh, this reminds me a lot of MooTools' optional FX package back in the early aughts. I've still got it in a couple places because it's been difficult to replace.

Just joining in with the “Wow, this is amazing” crowd. I usually detest websites that dink with scrolling to animate content in and out of view, except for well designed long form narrative content; but this is slick.

A challenge to all the “10x-ed my productivity” LLManiacs: how long to recreate this landing page using nothing but prompts (and how much $$ for a how-to course :)

A challenge to the “the’re gonna take our jobs” LLMongers: git gud, its possible. this is living proof.

(yes, i did just want to post those portmanteaus, even though it was all ChatGPT: https://pastebin.com/zrsj6DcB )

This works really well on the less conventional android browsers I use. Kudos to them, says good things about the library.

This is insane. API looks great, landing page is the best thing I've ever seen and just so feature rich. I wish I had a way to use this in my primary application.

This is INCREDIBLE. What! I could spend hours just playing around with the hecking documentation pages. EVERYTHING is so well thought out AND presented. I'm in awe.

The landing page is amazing!

The only issue I found with it was when checking the responsive layout example, I tried to resize my browser window and then the scroll was reset to top :(

  • Handling resize is a different beast than being responsive. Working for every viewport dimension under the sun is not the same thing as gracefully handling an animation while the viewport size changes - the latter is much more challenging.

    • I agree, I was not even expecting it to handle the resize well. I just thought the landing page wanted me to resize my window to test responsiveness (before I noticed that the animation itself changes the content area size).

      That being said, when resizing a window, the scrollbar should not reset/jump to top. At the very least, it should revert to what it was when going back to full size.

Anyone remembers DHMTL from Internet Explorer 4.0? From that - to this. What an evolution of web technologies.

  • I was just working on a "web app" for personal use yesterday where I'm doing document.getElementById and so forth. It still works ¯\_(ツ)_/¯

This is why I love HN. Not sure if I would have gotten the memo... Impressive tech, useful lib, super awesome landing page. Just blown away!

I feel like web tech is getting a lot more mature and reliable. Just my personal vibe-read, but JS libs on the whole seem to be getting to be consistently hitting higher quality bars.

Bravo, been looking forward to this but AnimeJs v3 has just been so solid for so long honestly you did amazing on v3 that v4 is just icing on top; excited to try this out on my next project.

async/await + animation (ie- with AnimeJS) is highly underrated.

And mad props for skipping the now dying trend of refactoring entire codebase to TypeScript :)

It could just be me running a CPU that's too old or an unconventional browser (Microsoft Edge), but the website is extremely laggy (less than 1 update per second) and the tab immediately starts using 80% of my CPU with fans blaring. Got an 8th gen Intel i7 if it matters.

  • What GPU do you have?

    • It's a laptop GPU - there's the integrated Intel UHD Graphics 620 card and the dedicated NVIDIA GeForce MX150. Both are pretty old (6-7 years?) but are capable of running most 3D games so I was a bit surprised.

      EDIT: P.S. What might help debug is that I have hardware acceleration enabled in the browser, but the GPU is not doing any work on the animejs homepage. For e.g. YouTube, the GPU does a lot of work so I've verified hardware accel works.

How does it compare to Motion ?

Are today's LLMs capable of writing code using these animation libraries? Could you replicate the landing page from its description, for example?

I stared at the homepage on my smartphone for a while and thought "That's really quite good." Then I started scrolling...

<mind>me</blown>

I remember using the same library few years ago for a stagger effect. Glad to see it's still alive and doing even better. The intro experience was beautifully crafted. It has me convinced to add an use to my projects

I love how CSS Transforms are so efficient. This is a great lightweight alternative over GSAP.

Quite impressive, and the showcase of breaking changes on the git repo gives the impression this release comes with a much nicer API than the previous one.

Love that the source is in Javascript, with type annotations. The compiled files in the /lib folder are also much smaller than I expected. I will likely be using this.

This cartoon show is almost like a web page!

Incidentally it crashed the browser the second time I looked at it.

I can feel the rotary dials tick on my mouse scrollwheel :-)

How was the model on the homepage created?

just as others mentioned, the whole landing page and the docs page is really nice work. It was loading well and the final scroll to bottom :). Thanks for the library and the work put in.

this is amazing, in my experience I haven't found much utility for visualization heavy UX. Like professionally.

I have spun up landing pages and things for things I've monetized. The crypto crowd loves it. But I don't put that stuff on my resume

What do you all use snazzy UX for?

I do find creating and expressing myself this way to be fulfilling though. Which is good enough, I just never considered myself doing it for the art and art communities. Websites aren’t really consumed that way.

Devs, please don't use this. it is unusable for me when browsing in a VM with a pretty snappy internet connection. The only other site that has compute/graphics resource issues for me is Netflix (its competition Prime, Youtube,etc.. have no issues, so i can only presume bad software dev decisions).

  • This has nothing to do with internet connection and everything to do with hardware accelerated graphics.
