Simply put, events are the things that trigger your functions to run.
If you are using Apache OpenWhisk as your provider, all
events in the service are anything in Apache OpenWhisk that can trigger your Actions, like HTTP endpoints, message queues, database updates and cron-scheduled 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.
Events belong to each Function and can be found in the
events property in
# '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: GET /users/create
events property is an array, because it is possible for functions to be triggered by multiple events, as shown
You can set multiple Events per Function, as long as that is supported by Apache OpenWhisk.
# 'functions' in serverless.yml functions: createUser: # Function name handler: handler.users # Reference to file handler.js & exported function 'users' events: # All events associated with this function - http: GET /users/create - http: POST /users/update - trigger: 'custom trigger'
The Serverless Framework supports all of the Apache OpenWhisk 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.
