Architecture

Functions are triggered by Azure EventGrid events published by the main app — they are never called directly via HTTP from the client. Each function handles one async concern:

Flow

App (createMessage) → Azure EventGrid → processPushNotification
                                      → processWebhook
                                      → pushWebhook
Copy

Dependencies

• @azure/functions — Azure Functions runtime
• @azure/eventgrid — EventGrid event parsing
• @azure/web-pubsub — WebPubSub real-time delivery
• @esposter/db + @esposter/db-schema — database access
