This template defines User, Photo, and Capture Management with secure sharing features and access controls so teams can implement a compelling photo-sharing experience quickly.

Core Candid Daily Photo Sharing Features

Every technology card in this hub uses the same candid daily photo sharing backend schema with User, Photo, and Dual-Camera Management.

User management

User class stores username, email, password, and roles.

Photo sharing management

Photo class links owner, content, and time lock attributes.

Dual-camera capture management

Manage state and capture data from multiple cameras.

Why Build Your Candid Daily Photo Sharing Backend with Back4app?

Back4app gives you photo and upload management primitives so your team can focus on user engagement and product enhancements instead of infrastructure.

  • •Photo and upload management: Photo class with permissions and management class for dual-camera capture supports creative sharing.
  • •Secure sharing and visibility features: Manage photo access with permissions and time-locks to enhance user experiences.
  • •Realtime + API flexibility: Use Live Queries for photo updates while keeping REST and GraphQL available for every client.

Build and iterate on photo-sharing features quickly with one backend contract across all platforms.

Build with AI Agent

Use the Back4app AI Agent to generate a real candid daily photo sharing app from this template, including frontend, backend, auth, and photo management flows.

Back4app AI Agent
Ready to build
Create a candid daily photo sharing 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. Photo: owner (Pointer to User, required), content (String, required), timeLock (Date, required); objectId, createdAt, updatedAt (system).
3. Capture Management: dual-camera features (required); objectId, createdAt, updatedAt (system).

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

Auth:
- Sign-up, login, logout.

Behavior:
- List users, upload photos, set time-locks for uploads, manage dual-camera states.

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