Overview

An interactive live video platform needs synchronized events, real-time participation, and reward logic.

This template defines User, Event, Participation, and Rewards with proper reward logic features and access controls to quickly implement engagement.

Core Interactive Live Video Features

Every technology card in this hub uses the same interactive live video backend schema with User, Event, Participation, and Rewards.

User management

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

Event scheduling and management

Event class links title, description, and time.

Participation tracking

Participation class stores user references and event references.

Reward management

Rewards class tracks points awarded for participation.

Why Build Your Interactive Live Video Platform Backend with Back4app?

Back4app gives you event, participation, and reward primitives so your team can focus on user engagement instead of infrastructure.

  • •Event management and participation tracking: Event class with timing and detail management supports user engagement.
  • •Real-time interaction and rewards features: Manage user engagement with reward mechanisms and instant participation updates.
  • •Flexible API access: Use REST and GraphQL APIs for diverse client access needs, keeping user experience consistent.

Build and iterate on interactive video platform features quickly with one backend contract across all platforms.

Build with AI Agent

Use the Back4app AI Agent to generate a real interactive live video app from this template, including frontend, backend, auth, and event, participation, and reward flows.

Back4app AI Agent
Ready to build
Create an interactive live video platform backend on Back4app with this exact schema and behavior.

Schema:
1. User (use Back4app built-in): username, email, password; objectId, createdAt, updatedAt (system).
2. Event: title (String, required), description (String), time (Date, required); objectId, createdAt, updatedAt (system).
3. Participation: user (Pointer to User, required), event (Pointer to Event, required); objectId, createdAt, updatedAt (system).
4. Rewards: user (Pointer to User, required), points (Number, required), timestamp (Date, required); objectId, createdAt, updatedAt (system).

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

Auth:
- Sign-up, login, logout.

Behavior:
- List users, schedule events, track participation, and allocate rewards.

Deliver:
- Back4app app with schema, ACLs, CLPs; frontend for user profiles, events, participations, and rewards management.
