What is deepstream?
deepstream is an open realtime server designed for mobile, web, and IoT applications. It allows clients and backend services to synchronize data, send events, and execute request-response workflows with a heavy emphasis on security. The server can be configured entirely on the server side without writing any code, while still integrating with popular caches, databases, and message buses.
The platform provides features such as realtime document sync for interactive JSON documents, publish-subscribe messaging for events, and request-response workflows via RPCs. It also includes presence monitoring for tracking online users and reactive subscriptions that notify services when new topics are subscribed to, enabling on-demand realtime data serving.
Features
- Records Realtime Document Sync: Interactive JSON documents that can be edited and observed, with changes persisted and synced across clients and saved in cache/storage.
- Events Publish-Subscribe Messaging: Many clients can subscribe to topics and receive data whenever other clients publish it to the same topic.
- RPCs Request-Response Workflows: Clients can register functions to be called by other clients, with smart routing of requests and responses.
- Presence Monitoring: Query for online users and subscribe to login/logout events.
- Listening Reactive Subscriptions: Services are notified whenever a new topic is subscribed to, enabling realtime data serving on demand.
- Security Authorize Everything: Authenticate and permission everything from the user down to each message.
Use Cases
- Building realtime collaborative applications
- Developing IoT systems with live data updates
- Creating interactive web and mobile apps with synchronized data
- Implementing publish-subscribe messaging for event-driven architectures
- Managing online user presence in multiplayer or social applications
