Ably Realtime for React/TypeScript

Ably Realtime is a platform for building scalable real-time applications with pub-sub messaging, presence tracking, collaborative features, chat, and database synchronization.

When to Use Each Feature

Ably provides different abstractions for different real-time use cases:

• Channels (Core Pub-Sub): Custom real-time messaging, notifications, live updates, event broadcasting
• Spaces: Participant state in collaborative UIs (live cursors, avatar stacks, user locations, component locking)
• LiveObjects: Application state synchronization (counters, voting, shared configurations, game state) with conflict-free updates
• Chat SDK: Complete messaging apps (1:1 chat, group conversations, livestream chat, support tickets)
• LiveSync: Database-to-client synchronization (broadcasting Postgres changes, outbox pattern, transactional consistency)
