Realtime — WebSocket Communication

Sails provides two tiers of realtime support via sails-hook-sockets: low-level room-based messaging (sails.sockets) and high-level model-centric notifications (Resourceful PubSub). Both use Socket.IO under the hood and integrate seamlessly with Sails' request lifecycle.

When to Use

Use this skill when:

• Building chat, messaging, or collaborative features
• Sending live notifications to specific users or groups
• Broadcasting model changes (created, updated, destroyed) to subscribers
• Tracking online presence or user status
• Creating live dashboards with auto-updating data
• Configuring WebSocket security, Redis adapters, or multi-server deployment
• Integrating sails.io.js with React, Vue, or Svelte frontends
