Build with AI Agent

Use the Back4app AI Agent to generate a fully functioning no-code web app backend, including frontend, backend, auth, and backend flows.

Back4app AI Agent
Ready to build
Create a no-code web 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. Data Module: owner (Pointer to User, required), content (String, required), permissions (Array of Strings, required); objectId, createdAt, updatedAt (system).

Security:
- Only the user can update/delete their profile. Only the owner can create/delete their data modules. Use Cloud Code for validation.

Auth:
- Sign-up, login, logout.

Behavior:
- List users, manage data modules with their content, and enable access control.

Deliver:
- Back4app app with schema, ACLs, CLPs; frontend for user profiles and data module management.
