AuraJS Game Developer API Handbook

This page is the grouped index for the public AuraJS handbook.

If you are new, do not start here. Start with Start Here. If you want the truthful default-versus-supported starter boundary, use Supported Starter Catalog. If you want the shortest room-code multiplayer path, use Multiplayer Quickstart. If you want the fuller placement guide, use Handling State and Content.
