Up to date UI Hook best practice?

Hello all,

I’m playing around with “https://github.com/gwendall/meteor-blaze-animations” but found that the callback doesn’t trigger as expected. I’m not sure why, tried google around but found no hint.

Just curious, what is the up to date or latest stable package to handle element in out animation? What is the best practice or recommended approach?

Which animation package is recommended? Please advice, thank you.
