• 🚀 API https://api.crl-devrel.net/
• 🚀 APP https://cockroachdb-edge-locations.vercel.app/

Deployment (Prod)

Deployment for three regions is handled when a push or merge occurs on the main branch. This is handled by the a GitHub Action: ./.github/workflows/build-me.yaml

Deployment (Dev)

Deploy all three regions in one hit

npm run deploy

Deployment (Local | serverless)

The default region is us-east-1. Using the below deploys to the default region.

serverless deploy

Deployment (Local | serverless - regions)

To deploy to additional regions use the below.

serverless deploy --region eu-central-1
serverless deploy --region us-west-1

Infrastructure

Each Lambda is deployed to a region. The region also requires a custom domain and ACM certificate mapping. Each API can then be used by Route 53 which routes traffic by geographical A records in Hosted Zones.
