awsCompileS3Events

This plugins compiles the function related S3 events in serverless.yaml to CloudFormation resources.

How it works

awsCompileS3Events hooks into the compileEvents hook of the deploy plugin.

It loops over all functions which are defined in serverless.yaml.

Inside the function loop it loops over all the defined S3 events in the events section and will create a S3 bucket resource with the corresponding lambda notification configuration for the current function and the s3:objectCreated:* events.

Furthermore a lambda permission for the current function is created which makes is possible to call the function when the s3:objectCreated:* event is fired.

Those two resources are then merged into the serverless.service.resources.aws.Resources section.
