Run

• we have two docker composes - one for local development and one for CI

docker-compose -f docker-compose.yml -f docker-compose.dev.yml up

S3 ui

• open localhost:9001 in browser

Important

• should not run npm install outside of docker container!
• can cause differences in package versions and dependencies

Caveats

• aws supports node14 in lambda

Entry points

• lambda.ts to run in lambda
• local.ts for local development

Dependency injection

• we want to have well organized code
• rely on well used practices - MVC
• dependency injection - central place orchestrating dependencies
