Learn SERVERLESS-STACK with Real Code Examples

SST simplifies serverless development by pairing CDK infrastructure with a high-productivity local dev environment.

Live Lambda Reloading lets developers instantly test Lambda changes without redeploying.

Provides opinionated yet extensible constructs for API, storage, queues, auth, and more.

Works seamlessly with React, Next.js, SvelteKit, Astro, and static frontends.

Ideal for modern cloud-native, scalable, pay-per-use applications.

Infrastructure as code (CDK)

Lambda-based backend services

DynamoDB/Postgres guides and helpers

Auth constructs (Cognito, Auth0, custom)

Static site + Next.js deployments

Stacks and constructs

Live Lambda Reloading environment

Function, API, Table, Bucket constructs

Cross-stack linking

Deployment stages

sst.config.ts (entry point)

packages/functions (Lambda code)

packages/core (shared utilities)

stacks/ (infrastructure)

frontend/ for UI frameworks

Define infrastructure via stacks

Implement Lambda functions

Connect resources using SST constructs

Test with `sst dev`

Deploy with `sst deploy`

Beginner: simple REST API with Lambda + DynamoDB

Intermediate: multi-stack app with auth and frontend

Advanced: event-driven workflow using SQS/EventBridge

Expert: microservices with multiple environments

Architect: full multi-stage CI/CD pipeline + observability
