Part of the SST Framework. The
sst CLI allows you to build, deploy, and test SST apps.
Create your first SST app.
# Create your app $ npm init sst $ cd my-sst-app $ npm i # Start Live Lambda Development $ npm start # Deploy to prod $ npx sst deploy --stage prod
Live Lambda Development
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!
