dj-truck-server is a production-ready GraphQL API built with Apollo Server and Express. It serves as the backend engine for a logistics-focused DJ platform, providing structured access to music data, user profiles, events, and authentication flows.

This server integrates multiple services into a single API layer using GraphQL schemas merged dynamically at startup. It supports both PostgreSQL and MySQL via Sequelize ORM and is highly configurable via environment variables.

Main features:

• GraphQL API with Apollo + Express
• Authentication via JWT and JWKs (Auth0 compatible)
• ORM support with Sequelize for both MySQL and PostgreSQL
• Dynamic schema merging from modular GraphQL files
• Middleware setup with cookie parsing and CORS
• Hot-reloading for local development with Nodemon

Use cases:

• Centralized backend for mobile/web DJ apps
• Authentication layer for multiple frontend clients
• Event and booking management through GraphQL
• Integration with music metadata APIs and audio file handling

Example flow:

POST /graphql
{
  user(id: 5) {
    name
    bookings {
      location
      date
    }
  }
}

The server is modular, easy to deploy, and structured to scale with the platform’s growing features. Designed for maintainability and flexibility.
