#Azure - Events

Simply put, events are the things that trigger your functions to run.

If you are using Azure Functions as your provider, all events in the service are anything in Azure Functions that can trigger your Functions, like HTTP endpoints, message queues, blob updates, and cron-scheduled events. In Azure Functions, events are called "Triggers" and are defined as a binding. You can also set additional input and output bindings which make it easy to get data from table storage or send message to queue services, for example.

View the Azure Functions events section for a list of supported events

Upon deployment, the framework will set up the Triggers and Rules that correspond to that event and configure your function to listen to it.

#Configuration

Events belong to each Function and can be found in the events property in serverless.yml.

# 'functions' in serverless.yml
functions:
  createUser: # Function name
    handler: handler.createUser # Reference to file handler.js & exported function 'createUser'
    events: # All events associated with this function
      - http: true

The events property is an array, in this case, because I can also use it do define my input and output bindings.

queuejs:
  handler: templates/handler.helloQueue
  events:
    - queue: YourQueueName
      x-azure-settings:
        connection: StorageAppSettingName
    - blob:
      x-azure-settings:
        name: bindingName
        direction: in

#Types

The Serverless Framework supports all of the Azure Functions events and more. Instead of listing them here, we've put them in a separate section, since they have a lot of configurations and functionality. Check out the events section for more information.

#Deploying

To deploy or update your Functions, Events and Routes, run serverless deploy.
