Request Description

SSR-Ready 🥳🎉

Adds native SSR support for all full-stack meta frameworks such as SvelteKit, Next, Nuxt and others that use server-side rendering under the hood.

So, Effekt can now be safely imported in all environments (ssr/client) without additional configs and will not cause possible server issues (500 undefined etc).

import { animate } from 'effekt'

animate('.el', {
  x: [0, 600, 300],
  background: ['#cf3', '#0df'],
  duration: 1,
})

Of course, client-side rendering works normally as expected.
