Re:Motion One: The Web Animations API for Everyone by SirHound on Tuesday September 21, 2021 @12:00PM (#28606439)
Hi HN! I'm Matt, author of Framer Motion and Popmotion. Today I'm launching my side-project, Motion One.

It's a new animation library built on the Web Animations API (WAAPI). I actually started this project as a book, but repeatedly found myself explaining some odd concepts (like fill mode) that I felt quite strongly that users shouldn't have to care about. I also discovered the state of WAAPI's implementation is very inconsistent across browsers despite green lights across caniuse [1].

Motion One makes WAAPI easier to use by presenting it with a simple API that also smoothes over browser inconsistencies [2].

It also adds all the features you'd expect from a modern JS animation library, like timelines, independent transform animations, and soon, springs.

Being built on WAAPI, it can create hardware accelerated animations. And it does all this in a bundlesize that is half that of Anime.js and less than a fifth of Greensock [3].

Feedback, questions and suggestions are welcome!
