SST v3 (Ion)

SST v3 is a framework for defining and deploying full-stack applications on AWS. It uses Pulumi under the hood but exposes a simpler component API. All infrastructure is defined in TypeScript in sst.config.ts.

Important: SST v3 vs v2

SST v3 (Ion) is a complete rewrite from v2. Key differences:

Aspect SST v2 (Constructs) SST v3 (Ion)
Engine AWS CDK Pulumi/Terraform
Config stacks/ directory Single sst.config.ts
Components new Table(stack, ...) new sst.aws.Dynamo(...)
Subscribers .addConsumers() .subscribe()
Linking bind: [...] link: [...]
SDK import import { Config } from 'sst/node/config' import { Resource } from 'sst'

Never generate SST v2 code. Always use the v3 patterns below.
