Please build a RESTful node/express server app that ....
- supports authentication with username and password (no need for OAuth)
- Reads/writes from a flat file JSON-formatted database called ‘./database.json’
- The database has these collections: products, users, orders
- Products have id, name, price, category, on_hand, description
- Users have username, street_address, email, password, first, last, and role
- Orders have id, username,order_date, ship_address, and an array of {product_id, quantity, price}
- Has a search for products capability by name or category
- Has a checkout endpoint so the user can check out. It pretends to charge the user’s credit card and adds the placed order to the orders collection.
- The products GET endpoint is open to all
- The products PATCH, POST, and DELETE endpoints are only open to admins.
- The users endpoints are open to admins and the current user. (They can read their own info).
- Users can read their own orders. Admins can fully edit and read all orders.
