Anime.js for HyperFrames HyperFrames can seek Anime.js instances through its animejs runtime adapter. The composition owns the animation objects; HyperFrames owns the clock. Contract Create animations or timelines synchronously during composition initialization. Set autoplay: false so Anime.js does not advance on its own clock. Register every returned animation or timeline on window.__hfAnime . Use finite durations and loop counts. Avoid callbacks that mutate DOM based on wall-clock time, network state, or unseeded randomness. The adapter seeks every registered instance with instance.seek(timeMs) , where timeMs is HyperFrames time in milliseconds. Basic Pattern < script src = " https://cdn.jsdelivr.net/npm/animejs@4.0.2/lib/anime.iife.min.js "
</ script
< script
const anim = anime ( { targets : ".mark" , translateX : 280 , rotate : "1turn" , opacity : [ 0 , 1 ] , duration : 1200 , easing : "easeOutExpo" , autoplay : false , } ) ; window . __hfAnime = window . __hfAnime || [ ] ; window . __hfAnime . push ( anim ) ; </ script
Timeline Pattern < script
const tl = anime . timeline ( { autoplay : false , easing : "easeOutCubic" , } ) ; tl . add ( { targets : ".title" , translateY : [ 40 , 0 ] , opacity : [ 0 , 1 ] , duration : 650 , } ) . add ( { targets : ".accent" , scaleX : [ 0 , 1 ] , duration : 450 , } , 250 , ) ; window . __hfAnime = window . __hfAnime || [ ] ; window . __hfAnime . push ( tl ) ; </ script
Module Builds If you use an ES module build, the adapter does not care how the instance was created. It only needs the returned object to expose seek() , pause() , and preferably play() : < script type = " module "
import { animate } from "https://cdn.jsdelivr.net/npm/animejs/+esm" ; const anim = animate ( ".chip" , { x : "18rem" , duration : 900 , autoplay : false , } ) ; window . __hfAnime = window . __hfAnime || [ ] ; window . __hfAnime . push ( anim ) ; </ script
Good Uses Small SVG and DOM flourishes where Anime.js syntax is compact. Imported Anime.js examples that can be made seek-driven. Multiple independent micro-animations pushed into the same registry. Use GSAP for complex scene sequencing unless the user specifically asks for Anime.js. GSAP is still the primary HyperFrames authoring path. Avoid Leaving autoplay at the Anime.js default. Depending on anime.running auto-discovery instead of explicit window.__hfAnime.push(...) . Infinite loops. Compute a finite repeat count from the composition duration. Building animations in timers, promises, event handlers, or after async asset loads. Validation After editing a composition that uses Anime.js: npx hyperframes lint npx hyperframes validate Credits And References HyperFrames adapter source: packages/core/src/runtime/adapters/animejs.ts .
