Real-time Updates
Build collaborative and live applications with built-in WebSocket support. When data changes, all connected clients update instantly — no polling, no delays, no extra code.
Live Data, Zero Effort
Real-time features are no longer optional — users expect instant updates. Baasix makes building live applications as easy as building static ones.
With Baasix, real-time subscriptions work out of the box. Subscribe to a collection, and your client receives updates whenever records are created, updated, or deleted. Whether you're building a chat app, a collaborative document editor, or a live dashboard, the same simple subscription pattern applies. Redis integration ensures your real-time features scale to thousands of concurrent users.
- Subscribe to any collection or specific records
- Automatic notifications on create, update, and delete operations
- Filter subscriptions to only receive relevant updates
- Redis Pub/Sub for horizontal scaling across multiple servers
- Permission-aware: users only see updates they're allowed to see
- Works with the SDK for simple client-side integration
- Reconnection handling and offline support built in
Skip the WebSocket Complexity
Building real-time features from scratch is notoriously complex.
✓ With Baasix
- Subscribe to collections with one SDK call
- Automatic handling of reconnections
- Redis scaling configured with environment variable
- Permission-aware subscriptions by default
- Built-in presence and typing indicators
✗ Traditional Approach
- Set up WebSocket servers and manage connections
- Build reconnection logic and handle edge cases
- Configure Pub/Sub, message queues, and scaling
- Implement authorization checks for each event
- Build presence system from scratch
Real-time Capabilities
Collection Subscriptions
Subscribe to entire collections or filter by conditions. Get notified of all changes or just the ones that matter to you.
Automatic Sync
Client state stays synchronized automatically. No manual polling, no stale data, no complex merge logic.
Presence Awareness
See who's online, who's viewing the same resource, and typing indicators. Build truly collaborative experiences.
Push Notifications
Send real-time notifications to specific users or broadcast to everyone. Perfect for alerts and updates.
Redis Scaling
Built-in Redis adapter for multi-server deployments. Scale horizontally without changing your code.
Low Latency
Sub-50ms update delivery. Users see changes the moment they happen — ideal for interactive applications.
Horizontal Scaling
Scale to millions of concurrent connections with stateless architecture and Redis-powered synchronization.
Baasix is designed for horizontal scaling from the ground up. Deploy multiple server instances behind any load balancer, and Redis ensures all clients stay synchronized regardless of which server they're connected to. No sticky sessions required — pure stateless scaling.
Stateless Architecture
Each server instance is completely stateless. Add or remove instances dynamically based on demand.
Shared Redis State
Redis handles Pub/Sub, cache sharing, and session storage. All instances share the same state seamlessly.
Zero-Config Scaling
Just set REDIS_URL and deploy more instances. No complex clustering configuration required.
Load Balancer Ready
Works with any load balancer — Nginx, HAProxy, AWS ALB, or cloud provider solutions.
What You Can Build
Real-time enables entirely new categories of applications.
Chat Applications
Build Slack-like chat with real-time message delivery, typing indicators, online presence, and read receipts. All the pieces are ready.
Collaborative Tools
Notion-style documents, Figma-like design tools, or shared spreadsheets. Multiple users editing simultaneously with instant sync.
Live Dashboards
Real-time analytics, monitoring systems, and trading platforms. Data updates flow to dashboards the moment they're recorded.
Gaming & Interactive
Multiplayer game backends, live polling, auction systems, and interactive presentations. Low latency makes it all possible.
Real-time FAQ
How does Baasix handle thousands of concurrent connections?
Baasix uses Socket.IO with Redis adapter for horizontal scaling. You can run multiple server instances behind a load balancer, and Redis ensures all clients receive updates regardless of which server they're connected to.
What happens when a client loses connection?
The SDK automatically reconnects and resubscribes to previous channels. Any missed updates during the disconnection can be caught up via regular API calls or timestamp-based filtering.
Can I use real-time with custom events?
Absolutely. Beyond automatic collection subscriptions, you can emit custom events from hooks or endpoints. This enables complex real-time workflows tailored to your application.
Is real-time permission-aware?
Yes. Baasix checks permissions before delivering updates. A user subscribed to a collection will only receive updates for records they're allowed to see based on your permission rules.
