}Build with AI Agent
Use the Back4app AI Agent to generate a real marketplace app from this template, including frontend, backend, auth, and product, vendor, and order flows.
Create a global retail marketplace app backend on Back4app with this exact schema and behavior. Schema: 1. User (use Back4app built-in): username, email, password; objectId, createdAt, updatedAt (system). 2. Product: owner (Pointer to Vendor, required), description (String, required), prices (Array of Objects, required); objectId, createdAt, updatedAt (system). 3. Vendor: name (String, required), contact details (String), associated products (Array of Pointers to Product); objectId, createdAt, updatedAt (system). 4. Order: product (Pointer to Product, required), user (Pointer to User, required), status (String, required); objectId, createdAt, updatedAt (system). Security: - Only the user can update/delete their profile. Only the owner/vendor can create/delete their products. Use Cloud Code for validation. Auth: - Sign-up, login, logout. Behavior: - List users, manage products, create orders, and handle vendor access. Deliver: - Back4app app with schema, ACLs, CLPs; frontend for user profiles, product management, vendor tracking, and order processing.
