Backend - Initialize Express + TypeScript Server

Is your feature request related to a problem? Please describe.

The backend folder currently lacks a runnable API server, making it impossible to develop or test backend endpoints locally.

Describe the solution you'd like

Set up a TypeScript-based Express server with:

• A /health endpoint
• Routing support for future APIs
• Middleware for error handling and logging

Describe alternatives you've considered

• Using Fastify, which is faster, but Express provides simplicity and strong community support, making it ideal for contributors and long-term maintenance.

Use Case

Provides a foundation for all backend endpoints and microservice integrations, allowing the frontend and services to connect seamlessly.

Additional context

• Include ESLint for consistent code style
• Use nodemon for automatic server restarts during development
• Optional: integrate dotenv for environment variable management

Start by inspecting the backend folder and existing package configuration to find the server entry point and development scripts. Done means a TypeScript Express server runs locally, exposes /health, supports future routing, includes logging and error-handling middleware, and provides the requested lint and restart tooling.
