shyam-3045/justship-api — reverse-engineered prompt

I want you to build out this project into a working API for a simple shipping service called JustShip. It should let another app create and manage shipment records, track their status, and return clean JSON responses.

Please set up sensible routes, controllers, models, services, validation, error handling, and middleware so the code is organized and easy to extend. Use Redis where it makes sense for fast lookups or temporary data, and use the socket layer for live shipment or order status updates if that already fits the structure.

Make sure the server starts reliably from server.js, reads config from environment variables, and has clear setup instructions for running locally and with Docker. Keep it practical and not overengineered. If anything important is missing from the repo, create the needed files and wire them in. Look up current docs online if you need to.
