Join the SAM developers channel (#samdev) on Slack to collaborate with fellow community members and the AWS SAM team.

sam is the AWS CLI tool for managing Serverless applications written with AWS Serverless Application Model (SAM). SAM CLI can be used to test functions locally, start a local API Gateway from a SAM template, validate a SAM template, fetch logs, generate sample payloads for various event sources, and generate a SAM project in your favorite Lambda Runtime.

• Develop and test your Lambda functions locally with sam local and Docker
• Invoke functions from known event sources such as Amazon S3, Amazon DynamoDB, Amazon Kinesis Streams, etc.
• Start local API Gateway from a SAM template, and quickly iterate over your functions with hot-reloading
• Validate SAM templates
• Get started with boilerplate Serverless Service in your chosen Lambda Runtime sam init

Learn how to get started using the SAM CLI with these guides:

• Installation: Set up your macOS, Linux or Windows Machine to run serverless projects with SAM CLI.
• Introduction to SAM and SAM CLI What is SAM and SAM CLI, and how can you use it to make a simple hello-world app.
• Running and debugging serverless applications locally: Describes how to use SAM CLI for invoking Lambda functions locally, running automated tests, fetching logs, and debugging applications
• Packaging and deploying your application: Deploy your local application using an S3 bucket, and AWS CloudFormation.
• Advanced: Learn how to work with compiled languages (such as Java and .NET), configure IAM credentials, provide environment variables, and more.
