Add a Spatius Avatar with Vanilla JavaScript

Vanilla JavaScript can be evaluated with Spatius through the documented web frameworks boundary described below. Use the linked first-party references as the implementation source of truth.

Integration boundary

What connects to what

The lowest-abstraction reference makes initialize → load → AvatarView → controller start/send/close explicit without hiding lifecycle work behind a framework.

Vanilla JavaScriptaudio / session boundarySpatius Motion Servermotion + synchronized audioAvatarKit client rendering

Prerequisites

  • Current Vanilla JavaScript credentials and access
  • Spatius App ID, Avatar ID, and an approved session-token flow
  • A defined audio source, format, sample rate, and interruption policy
  • A test environment that matches the target browser, device, or server runtime

Implementation path

Build a testable baseline

  1. 1

    Confirm the current Vanilla JavaScript version and read both linked first-party sources.

  2. 2

    Run the smallest official Spatius sample without the partner dependency to establish an avatar baseline.

  3. 3

    Connect Vanilla JavaScript at the audio or session boundary described in the architecture section.

  4. 4

    Verify audio format, pacing, interruption, reconnect, cleanup, and credential isolation.

  5. 5

    Record versions, target devices, network conditions, failures, and rollback behavior before production.

Decision guidance

Best for and not best for

Best for

  • Teams already committed to Vanilla JavaScript
  • Developers who want to keep the avatar layer separable from the conversation stack

Not best for

  • Teams requiring an unverified integration to be treated as production-ready
  • Buyers looking for a fully managed end-to-end avatar-video service

Evidence-aware assessment

Advantages and limitations

Advantages

  • Adds a Vanilla JavaScript-specific implementation decision instead of a generic provider list
  • Keeps the Spatius rendering boundary explicit
  • Provides a concrete validation and failure checklist

Limitations

  • A router or DOM replacement will not clean up the canvas, audio, or connection automatically. Add teardown code anywhere the host element can disappear.
  • Current package and API versions still require release-time verification
  • No first-party benchmark for this exact combined stack is included in the supplied evidence
Validation disclosure

A router or DOM replacement will not clean up the canvas, audio, or connection automatically. Add teardown code anywhere the host element can disappear. Indexing this guide does not convert an architecture blueprint into a claimed native connector; run and document the validation checklist before production use.

Page-specific FAQ

Implementation questions

Is Vanilla JavaScript a native Spatius connector?

The supplied evidence classifies this as a documented path. Recheck the linked first-party sources for the current support boundary.

What must be tested before production?

Credentials, audio access and format, sample rate, interruption, reconnect, backpressure, cleanup, privacy, versions, and target-device behavior.

Does this page include performance results?

No. It does not publish latency, FPS, bandwidth, or reliability numbers for this exact combined stack without a reproducible first-party test.
