Serverless configuration

The plugin is configured within the serverless.yaml by adding the plugin to the list of plugins.

plugins:
  - "@aligent/serverless-conventions"

Ignoring specific checks

All checks can be ignored by specifying the check to ignore under a top level property named conventions in serverless.yaml.

A list of all the available ignore commands are below:

conventions:
  ignore:
    serviceName: true
    stageName: true
    handlerName: true
    functionName: true
    handlerNameMatchesFunction: true
    dynamoDBTableName: true

Running the conventions check

The conventions check will run automatically each time you run a serverless command that compiles the packages. (e.g. serverless package, serverless deploy)

Alternatively, the conventions check can be run manually with serverless conventions-check.
