How crkr-dev/simple-deployment-app works
Simple Deployment App lets users create and view user records. The main workflow starts in the React UI, sends requests to the Express API, validates and dispatches them through controller and service layers, and persists records in MongoDB. The README also names Docker, Nginx, AWS, and GitHub Actions as part of the deployment stack, but the available evidence does not establish their runtime wiring, so they are not represented as connected product components.
