Props

Every orb implements the same contract, so they are interchangeable: swap the import and keep the props.

Prop	Type	Default	Description
state	'idle' \| 'connecting' \| 'listening' \| 'thinking' \| 'speaking' \| 'error' \| 'disabled'	'idle'	Assistant lifecycle state driving the animation. error and disabled are optional extensions.
size	number	160-184 (per orb)	Diameter of the orb in pixels, also exposed as the --orb-size CSS variable.
speed	number	1	Animation speed multiplier, also exposed as the --orb-speed CSS variable.
colorFrom	string	per-orb gradient start	Gradient start color (any CSS color), exposed as --orb-color-from.
colorTo	string	per-orb gradient end	Gradient end color (any CSS color), exposed as --orb-color-to.
levelRef	RefObject<number>	undefined	Live audio amplitude in 0..1 read every frame without re-render; a negative value falls back to the procedural animation.
label	string	'Assistant orb'	Accessible name announced by screen readers via aria-label.
className	string	undefined	Extra class names merged onto the root element.
ref	Ref<HTMLDivElement>	undefined	React 19 ref to the root element for measuring, animating or scrolling into view.

Usage

Copy the component files from the playground above, then render the orb with its default configuration.

import { EdgeGlow } from '@/registry/orbe/edge-glow/edge-glow';

export const Assistant = () => (
  <EdgeGlow
    state="idle"
    size={168}
    speed={1}
    colorFrom="#f472b6"
    colorTo="#60a5fa"
  />
);

Wire it to audio

Drive state from your assistant lifecycle and pass a levelRef with the live amplitude. The bundled useAudioLevel hook opens the microphone and writes a 0..1 level into the ref every frame without re-rendering; while the value is negative the orb falls back to its procedural animation.

'use client';
import { useState } from 'react';
import type { OrbState } from '@/registry/lib/orb-state';
import { useAudioLevel } from '@/registry/lib/use-audio-level';
import { EdgeGlow } from '@/registry/orbe/edge-glow/edge-glow';

export const Assistant = () => {
  const [state, setState] = useState<OrbState>('idle');
  const { levelRef } = useAudioLevel(state === 'listening');

  return <EdgeGlow state={state} levelRef={levelRef} />;
};
