Learn Serverless-stack - 1 Code Examples & CST Typing Practice Test
Serverless Stack (SST) is an open-source framework for building full-stack serverless applications on AWS. It provides a development environment with Live Lambda Reloading, infrastructure-as-code using SST constructs (powered by AWS CDK), and seamless integrations for APIs, databases, authentication, and frontends.

Frequently Asked Questions about Serverless-stack
What is Serverless-stack?
Serverless Stack (SST) is an open-source framework for building full-stack serverless applications on AWS. It provides a development environment with Live Lambda Reloading, infrastructure-as-code using SST constructs (powered by AWS CDK), and seamless integrations for APIs, databases, authentication, and frontends.
What are the primary use cases for Serverless-stack?
Building serverless APIs. Full-stack apps using AWS Lambda + DynamoDB. Event-driven architectures using SQS, SNS, EventBridge. Real-time apps using WebSocket or API Gateway. Deploying React/Next.js frontends with backend integration
What are the strengths of Serverless-stack?
Fast feedback loop with Live Lambda. Full-stack support (backend + frontend). Strong TypeScript ecosystem. Simplifies complex AWS CDK patterns. Great documentation and community
What are the limitations of Serverless-stack?
AWS-only (no multi-cloud). CDK learning curve for beginners. Live Lambda mode not ideal for every workflow. Deployment speed still depends on CloudFormation. Not suited for extremely latency-sensitive workloads
How can I practice Serverless-stack typing speed?
