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
