AWS SAM transform





The AWS Serverless Application Model (AWS SAM) transform is a AWS CloudFormation macro that transforms SAM templates into CloudFormation templates.
To use the SAM transform, add AWS::Serverless-2016-10-31 to the Transform section of your CloudFormation template.
Benefits of using the SAM transform include:

Built-in best practices and sane defaults.
Local testing and debugging with the AWS SAM CLI.
Extension of the CloudFormation template syntax.

Getting started
Save the following as template.yaml:
Transform: AWS::Serverless-2016-10-31
Resources:
MyFunction:
Type: AWS::Serverless::Function
Properties:
Runtime: nodejs18.x
Handler: index.handler
InlineCode: |
exports.handler = async (event) => {
console.log(event);
}

And deploy it with the SAM CLI:
sam sync --stack-name sam-app

The AWS::Serverless::Function resource will create a AWS Lambda function that logs events it receives.
Under the hood, the template is transformed into the JSON equivalent of the following CloudFormation template:
Resources:
MyFunction:
Type: AWS::Lambda::Function
Properties:
Code:
ZipFile: |
exports.handler = async (event) => {
console.log(event);
}
Handler: index.handler
