Overview
The sse package enables bi-directional communication between clients and servers using Server-Sent Events (SSE) and supporting POST requests. It provides a straightforward way to establish real-time data streams from server to client, ideal for live updates, notifications, or event-driven applications. The package includes both client and server implementations, allowing developers to build full SSE-based workflows within Dart and Flutter apps. It is designed for use in environments where persistent, lightweight, and efficient communication is needed without the overhead of WebSockets.
Use cases
- Real-time notifications
- Live data streaming
- Event-driven UI updates
- Server-to-client messaging
- Monitoring and logging
Key features
- Bidirectional communication via SSE
- Support for POST requests
- Client and server implementations
- Lightweight and efficient
- Simple API for event handling
Suitable for
- Apps needing live updates
- Backend services with event broadcasting
- Dart/Flutter projects requiring real-time features
- Use cases where WebSockets are too heavy
- Development teams using Dart on server and client
Considerations
- Limited to server-to-client streaming (unless combined with other methods)
- No built-in authentication or security
- Requires compatible server setup
- Not suitable for high-frequency bidirectional messaging
- Depends on stable network connectivity
