Security and Permissions
How ACL and CLP strategy secures users, posts, comments, and connections.
User-controlled profile privacy
Only the user can edit or remove their profile data; others have restricted access.
Content integrity management
Only authors can create or delete their content. Validation is managed with Cloud Code.
Scoped read access
Restrict content reads to relevant users (e.g., users can only see their posts and comments).
Schema (JSON)
Raw JSON schema definition ready to copy into Back4app or utilize as implementation reference.

}Build with AI Agent
Use the Back4app AI Agent to generate a real social networking app from this template, including frontend, backend, auth, posts, comments, and user management.
Create a social networking 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. Post: author (Pointer to User, required), content (String, required), interactions (Array, required); objectId, createdAt, updatedAt (system). 3. Comment: postId (Pointer to Post, required), userId (Pointer to User, required), content (String, required); objectId, createdAt, updatedAt (system). 4. Connection: userId (Pointer to User, required), connectionId (Pointer to User, required); objectId, createdAt, updatedAt (system). Security: - Only the user can update or delete their profile. Only the author can create or delete their content. Validation is handled in Cloud Code. Auth: - Sign-up, login, logout. Behavior: - List users, create posts, comment on posts, and manage connections. Deliver: - Back4app app with schema, ACLs, CLPs; frontend for user profiles, posts, comments, and connections.
