Serverless Stack Toolkit (SST)

Serverless Stack Toolkit (SST) is an extension of AWS CDK that:

• Includes a Live Lambda Development environment
• With zero-config support for ES and TypeScript using esbuild
• Allows you to use CDK with Serverless Framework

SST also supports deploying your CloudFormation stacks asynchronously. Seed natively supports concurrent asynchronous deployments for your SST apps. And SST deployments on Seed are free!

SST also comes with a few other niceties:

• Automatically lints your code using ESLint
• Runs your unit tests using Jest

Behind the scenes, SST uses a lightweight fork of AWS CDK to programmatically invoke the various CDK commands.

Create your first SST app.

$ npx create-serverless-stack@latest my-sst-app
$ cd my-sst-app
$ npx sst start

The sst start command starts up a local development environment that opens a WebSocket connection to your deployed app and proxies any Lambda requests to your local machine. This allows you to:

• Work on your Lambda functions locally
• Supports all Lambda triggers, so there's no need to mock API Gateway, SQS, SNS, etc.
• Supports real Lambda environment variables and Lambda IAM permissions
• And it's fast. There's nothing to deploy when you make a change!
