tetris_aws_go

Goals

The goal of this project was to create a full stack AWS native project template. The secondary goal is to keep the DTO types in sync between the frontend and backend using code generation. Here is the achieved stack:

• Backend:
  • Go
  • Lambda
  • ApiGateway
• Frontend:
  • Typescript
  • React
• Infrastructure:
  • Build Tool: Gradle and Yarn
  • Deployments: CDK
  • Authentication: Cognito
  • Api Definition: Smithy
  • Go Type Generation: smithy-go
  • Typescript Type Generation: smithy-typescript

Warnings

smithy-go Does not yet work. Track this issue to see updated status

The go and typescript type generation rely on smithy-go and smithy-typescript, both products are not yet GA. As such they still have some quirks to work through. Overall it seems that the typescript code generation tool is a bit more stable.

If you stumbled across this guide another resource that wasn't GA but looks promising is: aws-prototyping-sdk, specifically the type-safe-api.
