Optional Express and CLI

Skip if Hello World was enough — still tear down afterward. Pass the CLI gate before path B.

Both paths use demo/ and create a new revision under Latest revision.

A — console zip

Fewer leftovers than deploy.

cd demo

npm ci --omit=dev

zip -rq ../wf-hello.zip index.js package.json package-lock.json node_modules && ls -lh ../wf-hello.zip

Console → wf-hello → upload wf-hello.zip as a new revision → wait Active. Native modules need Arm64 (this demo has none).

B — CLI deploy

May create an IAM role and S3 objects — clean up in Teardown.

aws lambda-web deploy --name wf-hello --code ./demo --region us-east-1
