CLI framework for deploying and managing serverless applications on AWS Lambda with YAML infrastructure, local development, and multi-language runtime support.
The Serverless Framework – Makes it easy to use AWS Lambda and other managed cloud services to build applications that auto-scale, cost nothing when idle, and result in radically low maintenance.
The Serverless Framework is a command-line tool with approachable YAML syntax to deploy both your code and cloud infrastructure needed to make tons of serverless application use-cases, like APIs, front-ends, data pipelines and scheduled tasks. It's a multi-language framework that supports Node.js, Typescript, Python, Go, Java, and more. It's also completely extensible via over 1,000 plugins which add more serverless use-cases and workflows to the Framework.
