Lottie

Lottie for HyperFrames

HyperFrames can seek both lottie-web and dotLottie players through its lottie runtime adapter. Lottie is a strong fit because the animation timeline is already encoded in the asset; HyperFrames only needs a player object it can seek.

Contract

• Load assets from local project files, usually under assets/.
• Set autoplay: false.
• Prefer loop: false unless the user explicitly wants a loop.
• Register every returned animation or player on window.__hfLottie.
• Keep the Lottie container dimensions stable with CSS.

The adapter seeks lottie-web with goToAndStop(timeMs, false) and dotLottie with frame or percentage APIs depending on player shape.

lottie-web Pattern

  const anim = lottie.loadAnimation({
    container: document.getElementById("logo-lottie"),
    renderer: "svg",
    loop: false,
    autoplay: false,
    path: "assets/logo-reveal.json",
  });

  window.__hfLottie = window.__hfLottie || [];
  window.__hfLottie.push(anim);

.lottie-layer {
  width: 100%;
  height: 100%;
}

dotLottie Pattern

  const player = new DotLottie({
    canvas: document.getElementById("product-lottie"),
    src: "assets/product-flow.lottie",
    autoplay: false,
    loop: false,
  });

  window.__hfLottie = window.__hfLottie || [];
  window.__hfLottie.push(player);

.lottie-canvas {
  width: 100%;
  height: 100%;
  display: block;
}

Multiple Animations

Push each player into the same registry:

window.__hfLottie = window.__hfLottie || [];
window.__hfLottie.push(backgroundAnim);
window.__hfLottie.push(iconAnim);
window.__hfLottie.push(confettiAnim);

HyperFrames seeks them all to the same composition time.

Good Uses

• After Effects exports that are already known to render correctly in lottie-web.
• Logo reveals, icon loops, decorative accents, and product UI motion.
• Translating Remotion Lottie usage into plain HyperFrames HTML.

Avoid

• Relying on remote path URLs at render time.
• Starting playback with play().
• Assuming unsupported After Effects effects will survive export. Test the JSON or .lottie file in a browser first.
• Loading a player asynchronously and registering it after HyperFrames validation has already inspected the page.

Validation

After editing a Lottie composition:

npx hyperframes lint
npx hyperframes validate
