Simply put, events are the things that trigger your functions to run.
If you are using AWS as your provider, all
events in the service are anything in AWS that can trigger an AWS Lambda function, like an S3 bucket upload, an SNS topic, and HTTP endpoints created via API Gateway.
Upon deployment, the framework will deploy any infrastructure required for an event (e.g., an API Gateway endpoint) 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: path: users/create method: post
Events are objects, which can contain event-specific information.
events property is an array, because it's possible for functions to be triggered by multple events, as shown
You can set multiple Events per Function, as long as that is supported by AWS.
# '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: path: users/create method: post - http: path: users/update method: put - http: path: users/delete method: delete
The Serverless Framework supports all of the AWS Lambda 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.
