Medplum WebSocket Subscription Demo

An example demonstrating basic usage of WebSocket subscriptions

This example app demonstrates the following:

• Creating WebSocket Subscription resources
• Calling $get-ws-binding-token operation on created Subscriptions in order to get a token to bind to
• Connecting to the WebSocket subscription endpoint
• Creating a bind-with-token message to start receiving subscription notifications for Subscriptions associated with the provided token
• Disconnecting from the endpoint
• Cleaning up Subscriptions after finishing the session
