@remotedraw/protocol

Shared TypeScript types, Zod schemas, and constants for the RemoteDraw session/sender/stroke protocol. Framework-free and dependency-free beyond zod — this is the contract layer every other RemoteDraw package (@remotedraw/client, @remotedraw/react, @remotedraw/svelte) and the hosted API agree on.

What it provides:

• Request/response types for sessions, join tokens, senders, drawings, drafts, projections, and AI actions (CreateSessionRequest, JoinSessionResponse, SenderSubmitRequest, and friends).
• The value unions behind those types (sessionStatusValues, surfaceKindValues, drawingToolValues, aiActionKindValues, etc.) so clients can validate without re-declaring the protocol.
• REMOTEDRAW_LIMITS and DEFAULT_CAPABILITIES — the numeric limits and default capability set the hosted API enforces.
• packPoints / unpackPoints — the compact point codec used to transport strokes over the wire.

import type { CreateSessionRequest, CreateSessionResponse } from "@remotedraw/protocol";

const request: CreateSessionRequest = {
  target: { kind: "sketch" },
};

Most integrations consume this indirectly through @remotedraw/client, @remotedraw/react, or @remotedraw/svelte, which re-export it in full. Depend on it directly only for a package-free, type-only integration (the --sdk js RemoteDraw CLI starter).
