Hi, I'm the creator of Anime.js. Firstly, thank you for the submission. I honestly didn't anticipate being featured on the homepage of HN without any major update to the library! To those wondering why the project hasn't been updated recently, it's simply because I've been working on a new version (V4) for the last two years. The core library has been completely rewritten, I'm currently in the testing and documentation phase and should be ready for release by this summer.

Some of the new features of V4 include:

* Improved performance: The library has been entirely rewritten with performance optimization and low memory usage in mind.

* New ESM Module first API: Import only what you need and benefit from improved tree shaking.

* Better timelines: New options for animation positioning, allowing looping animations in timelines and improved parameters inheritance.

* Additive animations: A new tween composition mode that lets you smoothly blend concurrently running animations.

* Variable framerate: Specify different framerates for each animation or set it globally.

* New callbacks: onTick, onLoop, onRender, etc.

* Value modifiers: A function to modify or alter the behavior of the numerical values of the animated property value before rendering.

* Animate from: Animation from a given value to the current target value.

* Improved documentation: A new design with enhanced animations demos and more in-depth explanations.

* Unit tests

And much more! I can't wait to share it with you!

So another comment says that CSS Tweening makes your lib obsolete, which I don't think is true, but,

Can Anime.js make use of CSS Tweening on browsers that support it? Maybe as an optimization, rather than using requestAnimationFrame, on some kinds of animations

Not planned for now, but I haven't really looked into it. I'll consider after the V4 is released.

I am actually writing a piece right now on the best animation frameworks for React (Framer Motion, react-spring etc.)

Was including Amine when I found this very recent HN post. I'm curious, in your perspective, what are the benefits of using Amine over something like Framer Motion? And would you recommend using the react-amine npm package or doing a custom binding—couldn't tell if that package was official.

I would like to be among the testers, please. I prefer Anime over Gsap for all my projects.

Nice, Julian!

Is there any way to alpha/beta test for v4?

[JulianGarnier]

I've been considering offering early access exclusively to GitHub sponsors once the documentation and migration guide are completed.

Would this be something that interests you?

[jeanlucas]

Yes!

Why do your docs use `var` for variable declarations?

[JulianGarnier]

Because the docs have been written 4 years ago, and back then const and let weren’t widely used.

The upcoming documentation for V4 has been completely rewritten with up to date JavaScript.
