Message from @kvirani [August 22, 2016]: Hi folks, I have some exciting news to share. Julian has graciously offered and I have accepted to become the lead maintainer for Velocity. I'm really excited to be working closely with and learning from him in order to transition this project onto my plate. I remember when Julian started working on Velocity (locked away in his apartment — a few blocks away from me). Then later when he first announced it publicly. And finally when it exploded in growth from 0 to what it is today. I hope to bring that same enthusiasm, energy, and skill to it. I am honored to be taking it on. Looking forward to working on it along with the rest of the contributors.

Questions or Problems? Ask on StackOverflow (make sure you add the velocity.js and javascript tags).

  • CSS transitions are meant for simple interface flourishes.
  • jQuery's $.animate() is slow and poorly-equipped for motion design.
  • Velocity is a fast, feature-rich standalone alternative to jQuery's $.animate().
