DaoDuck3008/BE-DaoDuckWear-Clothing-Website — reverse-engineered prompt

Build me the backend for DaoDuckWear, an online clothing store, using the existing TypeScript Nest project as the starting point.

I want the site to support normal shop features like customer sign up and login, browsing clothes, viewing product details, filtering by category, size, color, and price, adding items to a cart, checking out, and seeing order history. There should also be an admin side in the API where staff can add and edit products, manage stock, see orders, and update order status.

Please inspect what’s already in the repo first and keep the code clean and consistent with the current setup. Add sensible validation, error messages, environment config, and tests where it makes sense. If the database setup isn’t already clear, choose a simple practical approach and document how to run it locally. Include a short README section with the main commands and example API usage. Look up current Nest docs online if you need to.
