To migrate Express routes to AWS Lambda, you map existing route logic into individual serverless Lambda handlers behind API Gateway, updating CDK stacks to reflect the new infrastructure without rewriting the application.

Converting an Express app into a serverless API involves mapping routes to Lambda functions, generating handlers, and updating CDK stacks through a guided three-phase process: Plan, Execute, and Verify.

Yes, updating your CDK stack is required when moving Express routes to API Gateway to define the new serverless AWS resources and route configurations for the Lambda functions.

Start an Express to Lambda migration by creating a plan at .migration/plan.md that maps your routes, then execute the migration steps to generate Lambda handlers and update infrastructure.

No, converting Express routes to Lambda does not require rewriting your application logic; it transforms existing route logic directly into serverless handlers to enable scalable deployment.
