IO Functions for Services

This project implements the APIs called by the 3rd party services. The implementation is based on the Azure Functions v2 runtime.

Architecture

The project is structured as follows:

• CreateMessage: handles the createMessage API, creates a Message document and forks the CreatedMessageOrchestrator durable function:
  • CreatedMessageOrchestrator: handles all the asynchronous activities involving the creation of a message, it calls the following activities:
    • StoreMessageContentActivity: stores the content of the message in a blob
    • MessageStatusUpdaterActivity: upsates the status of the Message document after the content of the message has been successfully stored
    • CreateNotificationActivity: creates a Notification document
    • EmailNotificationActivity: sends an email notification if needed
    • WebhookNotificationActivity: triggers a webhook call if needed
    • NotificationStatusUpdaterActivity: updates the Notification document with the results of the email or webhook notifications.
• GetMessage: handles the getMessage API for services
• GetLimitedProfile: handles the getProfile API for services
• GetSubscriptionsFeed: handles the getSubscriptionsFeedForDay API for services
