SST

Overview

SST (Serverless Stack) is a framework for building and deploying full-stack applications on AWS with high-level constructs for Lambda, API Gateway, DynamoDB, S3, and frontend frameworks. It features live local development connected to real AWS services, type-safe resource linking, and zero-config TypeScript support.

Instructions

When defining infrastructure, use

sst.config.ts

with typed components like

sst.aws.Function

sst.aws.Api

sst.aws.Bucket

, and

sst.aws.Dynamo

When connecting resources, use the
```
link
```
property on Functions to automatically grant IAM permissions and inject environment variables, and access linked resources via
```
Resource.Name
```
in handlers.
When developing locally, use
```
sst dev
```
which runs Lambda locally with hot reload while connected to real AWS services (DynamoDB, S3, SQS), with support for VS Code breakpoint debugging.

When deploying, use

sst deploy --stage prod

for named stages,

sst deploy --stage pr-${PR_NUMBER}

for preview environments, and

sst remove --stage dev

for teardown.

When deploying frontends, use
```
sst.aws.Nextjs
```
,
```
sst.aws.Remix
```
, or
```
sst.aws.Astro
```
components for SSR on Lambda with static assets on S3 + CloudFront.
When managing secrets, use
```
sst secret set KEY value
```
for encrypted, stage-specific secret storage.
When organizing code, keep handlers thin in
```
packages/functions/
```
as orchestrators, and place business logic in
```
packages/core/
```
.

Examples

Example 1: Build a serverless API with DynamoDB

User request: "Create a REST API on AWS with DynamoDB using SST"

Actions:

Define DynamoDB table and API Gateway in
```
sst.config.ts
```
Link the table to API handler functions for automatic permissions
Implement CRUD handlers accessing
```
Resource.MyTable.name
```
Run
```
sst dev
```
for live local development against real AWS services

Output: A serverless REST API with type-safe resource access and live debugging.

Example 2: Deploy a Next.js app with preview environments

User request: "Deploy my Next.js app on AWS with per-PR preview environments"

Actions:

Configure
```
sst.aws.Nextjs
```
component with custom domain and linked resources
Set up CI to run
```
sst deploy --stage pr-${PR_NUMBER}
```
for each pull request
Link backend resources (API, database) to the Next.js deployment
Add cleanup step with
```
sst remove
```
when PR is closed

Output: A production Next.js deployment on AWS with isolated preview environments for each PR.

Guidelines

Use
```
link
```
instead of manual IAM policies; SST generates least-privilege permissions automatically.
Access linked resources via
```
Resource.Name
```
in handlers; never hardcode table names or bucket ARNs.
Use
```
sst dev
```
for daily development; it is faster than deploying to AWS on every change.
Create per-developer stages (
```
sst dev --stage alice
```
) so each developer gets isolated AWS resources.
Keep handlers thin: business logic in
```
packages/core/
```
, handlers in
```
packages/functions/
```
.
Use
```
sst secret
```
for API keys and credentials; they are encrypted and stage-specific.
Set up
```
sst deploy --stage pr-${PR_NUMBER}
```
in CI for preview environments on every pull request.
