AvatarKit UI

AvatarKit UI is a shadcn-style React component package for embedding a Spatius avatar player into your app. It wraps AvatarKit RTC setup, LiveKit session wiring, loading and error states, and a small set of presentational primitives so you can ship an avatar surface with minimal glue code.

Usage

Use SpatiusAvatarProvider to initialize AvatarKit and LiveKit, then compose the avatar surface with SpatiusAvatarFrame, SpatiusAvatarCanvas, SpatiusAvatarLoading, SpatiusAvatarError, and SpatiusAvatarStatus.

import {
  SpatiusAvatarCanvas,
  SpatiusAvatarError,
  SpatiusAvatarFrame,
  SpatiusAvatarLoading,
  SpatiusAvatarProvider,
  SpatiusAvatarStatus,
} from '@/components/spatius-avatar'

export function AgentAvatar({ token, url, roomName }: {
  token: string
  url: string
  roomName: string
}) {
  return (
    <SpatiusAvatarProvider
      appId={import.meta.env.VITE_SPATIUS_APP_ID}
      avatarId={import.meta.env.VITE_SPATIUS_AVATAR_ID}
      connection={{ token, url, roomName }}
    >
      <SpatiusAvatarFrame className="overflow-hidden">
        <SpatiusAvatarCanvas className="min-h-[520px]" />
        <SpatiusAvatarLoading />
        <SpatiusAvatarError />

        <div className="absolute inset-x-0 top-0 flex justify-end p-4">
          <SpatiusAvatarStatus />
        </div>
      </SpatiusAvatarFrame>
    </SpatiusAvatarProvider>
  )
}

This is the same composition pattern used in the working Vite demo: an avatar frame for rendering, built-in overlays for loading and failure states, and context-driven controls for microphone and session UI.

Adding microphone controls with context

Use useSpatiusAvatarContext() inside the provider tree when you want to drive UI from connection state or publish the local microphone into the avatar session.

import { useState } from 'react'

import {
  SpatiusAvatarCanvas,
  SpatiusAvatarError,
  SpatiusAvatarFrame,
  SpatiusAvatarLoading,
  SpatiusAvatarProvider,
  SpatiusAvatarStatus,
  useSpatiusAvatarContext,
} from '@/components/spatius-avatar'

function AvatarPanel() {
  const avatar = useSpatiusAvatarContext()
  const [pending, setPending] = useState(false)

  const toggleMicrophone = async () => {
    if (pending) return

    setPending(true)

    try {
      if (avatar.isPublishingMicrophone) {
        await avatar.stopPublishingMicrophone()
      } else {
        await avatar.startPublishingMicrophone()
      }
    } finally {
      setPending(false)
    }
  }

  return (
    <div className="grid gap-6 lg:grid-cols-[minmax(0,420px)_minmax(0,1fr)]">
      <section className="space-y-4">
        <SpatiusAvatarFrame>
          <SpatiusAvatarCanvas />
          <SpatiusAvatarLoading />
          <SpatiusAvatarError />
        </SpatiusAvatarFrame>

        <div className="flex items-center justify-between rounded-2xl border p-3">
          <button
            disabled={!avatar.isConnected || pending}
            onClick={() => void toggleMicrophone()}
            type="button"
          >
            {avatar.isPublishingMicrophone ? 'Mute mic' : 'Enable mic'}
          </button>

          <SpatiusAvatarStatus />
        </div>
      </section>

      <section className="rounded-3xl border p-4">
        {avatar.room
          ? 'Render your LiveKit transcript or agent UI here.'
          : 'Waiting for the LiveKit session to become available...'}
      </section>
    </div>
  )
}

export function VoiceAgentAvatar(props: {
  token: string
  url: string
  roomName: string
}) {
  return (
    <SpatiusAvatarProvider
      appId={import.meta.env.VITE_SPATIUS_APP_ID}
      avatarId={import.meta.env.VITE_SPATIUS_AVATAR_ID}
      connection={props}
    >
      <AvatarPanel />
    </SpatiusAvatarProvider>
  )
}

SpatiusAvatarCanvas must render inside a container with non-zero width and height. The provider waits for the canvas container to be measurable before it starts loading the avatar.

Features

Render a Spatius avatar surface with a small set of composable shadcn-style primitives.
Connect AvatarKit and LiveKit through SpatiusAvatarProvider without writing your own player wiring.
Show built-in loading, error, and connection status UI out of the box.
Access the active LiveKit room and avatar session state through useSpatiusAvatarContext().
Start, stop, reconnect, disconnect, and publish microphone audio with hook-based controls.

Installation

AvatarKit UI is built on:

shadcn/ui conventions (local component files + Tailwind styles)
LiveKit Agent UI ecosystem (@livekit/components-react, @livekit/components-styles)

Before adding this AvatarKit UI component to your project, you can use this guide to setup shadcn

npx shadcn@latest init
npx shadcn@latest add https://ui.spatius.ai/r/spatius-avatar.json

`useSpatiusAvatar(options)`

Low-level hook that powers the provider. Use it when you want to wire AvatarKit into your own context or compose a custom provider.

Options

useSpatiusAvatar() accepts the same connection and SDK props as SpatiusAvatarProvider, except for children, muted, volume, and onDisconnect.

const avatar = useSpatiusAvatar({
  appId,

  publishMicrophone: false,
})

`startPublishingMicrophone()`	`() => Promise<void>`	Publishes the local microphone into the avatar session.
`stopPublishingMicrophone()`	`() => Promise<void>`	Stops microphone publishing.

`useSpatiusAvatarContext()`

Returns the current avatar state from SpatiusAvatarProvider.

const avatar = useSpatiusAvatarContext()

Use this hook inside provider children to:

show or hide UI based on avatar.status
read the connected avatar.room for LiveKit chat and transcript components
call avatar.startPublishingMicrophone() and avatar.stopPublishingMicrophone()
invoke avatar.disconnect() or avatar.reconnect() from your own controls

useSpatiusAvatarContext() throws an error if it is used outside SpatiusAvatarProvider.
