Features

Cross-cutting capabilities of the SDK and the apps that ship it. Each page here pulls together work that lives in multiple packages.

Pages

• Multiplayer sync — the protocol, the room engine, the React hooks, and the production server.
• Shapes and tools — how ShapeUtil and StateNode connect, and the default set.
• Store and migrations — record types, the schema registry, and how migrations keep old documents loadable.
• UI system — the toolbar, panels, menus, dialogs, and the override mechanism.
• File formats and export — .tldr, image export, clipboard, embeds, external content.

What's not here

• Anything that lives in one package goes in the Packages section.
• App-specific features (e.g., dotcom folders) live in apps/dotcom.
• Foundational primitives (geometry, signals) live in Primitives.
