The AWS Serverless Application Model (SAM) CLI is an open-source CLI tool that helps you develop serverless applications containing Lambda functions, Step Functions, API Gateway, EventBridge, SQS, SNS and more. Some of the features it provides are:
sam localcommands on SAM and CDK applications
sam syncin your developer environments
sam pipeline init
To get started with building SAM-based applications, use the SAM CLI. SAM CLI provides a Lambda-like execution environment that lets you locally build, test, debug, and deploy AWS serverless applications.
Next Steps: Learn to build a more complex serverless application.
This Github Repository contains source code for SAM CLI. Here is the development team talking about this code:
SAM CLI code is written in Python. Source code is well documented, very modular, with 95% unit test coverage. It uses this awesome Python library called Click to manage the command line interaction and uses Docker to run Lambda functions locally. We think you'll like the code base. Clone it and run
./Make -pron Windows!
We love our contributors ❤️ We have over 100 contributors who have built various parts of the product. Read this testimonial from @ndobryanskyy to learn more about what it was like contributing to SAM.
