WebSocket Design

Realtime needs auth on connect, heartbeats, reconnect/resume, and backpressure. Do not treat sockets as free unlimited fan-out.

Workflow

  1. Use cases: notifications, collab, trading, presence.
  2. Auth: ticket/token on connect; revalidate on resume.
  3. Protocol: message types, versioning, compression.
  4. Scaling: sticky sessions, pub/sub fan-out, room design.
  5. Reliability: heartbeats, backoff reconnect, offline buffer.
  6. Backpressure and max message size.
  7. Observability: connects, drops, lag.

Output format

## Realtime design
**Channels:** …
**Auth:** …
**Message schema:** …
**Reconnect/resume:** …
**Scale plan:** …
**Limits:** …

Rules

  1. Authenticate before subscribing to private rooms.
  2. Validate every client message; never trust client as authority for money.
  3. Document idle timeouts and ping/pong.
  4. Prefer idempotent event ids for delivery.
  5. Separate public broadcast from private streams.

Edge cases

  • Mobile networks: aggressive reconnect.
  • Horizontal scale: avoid single-node presence without store.
  • Browser limits: connection count per origin.
