Monolithic Server Configuration #639
Description
Description: The server.js file is a large entry point with route registrations, middleware setup, Socket.IO handling, and database connections all in one place. This makes it difficult to scale, test individual components, and onboard new developers. Security and CORS configurations are also embedded here.
Steps to Refactor:
Extract route registrations into a separate file (e.g., routes/index.js) that imports and applies all route modules.
Move middleware setup (e.g., security, CORS, rate limiting) into a config/middleware.js file.
Create a config/socket.js for Socket.IO setup and event handling.
Use environment-based configuration (e.g., via a config/index.js) for database connections and server settings.
Implement a modular startup process with async initialization (e.g., connect DB first, then start server).
Add integration tests for the server startup process.
