What it is and what it does
This package is a Python client library for Azure Web PubSub Service, a managed Azure service that handles real-time, bidirectional communication between servers and clients over WebSocket. It abstracts the complexity of managing WebSocket connections, allowing you to focus on application logic rather than connection lifecycle and message routing.
You use it server-side to send messages to all connected clients (broadcast), to specific groups, to individual users, or to particular connections. It also handles connection management tasks like organizing connections into groups, assigning users to connections, and revoking permissions. The library depends on azure-core for HTTP transport and authentication, isodate for timestamp handling, pyjwt for token operations, and typing-extensions for type hints.
Use it for
- Build real-time chat applications where messages must be delivered instantly to multiple connected clients.
- Send live notifications or alerts from a server to specific user groups or all connected clients.
- Implement collaborative features (shared whiteboards, live editing) requiring bidirectional, low-latency messaging.
- Manage dynamic user presence and connection state across multiple devices or browser tabs.
- Replace polling-based updates with push-based messaging for dashboards and monitoring applications.
