[TODO] Expand server.js into modular files

[gbowne1]

The backend and especially server.js will grow pretty big from adding functionality. This is somewhat psuedo coded as a example here but here's the proposed structure...

/src/
  server.js
  app.js
  config/
    db.js
    cors.js
  routes/
    authRoutes.js
    adminRoutes.js
    streamRoutes.js
    healthRoutes.js
  controllers/
    AuthControllers.js
    StreamController.js
  middleware/
    auth.js
  utils/
    paths.js

server.js will be somewhat similar. But all it does is start the server.

import 'dotenv/config';
import mongoose from 'mongoose';
import app from './app.js';

const PORT = process.env.PORT || 3000;
const MONGODB_URI = process.env.MONGODB_URI;

// Connect DB
if (MONGODB_URI) {
  mongoose
    .connect(MONGODB_URI)
    .then(() => console.log('🟢 MongoDB connected'))
    .catch(err => console.error('🔴 MongoDB error:', err));
} else {
  console.log('⚠️ No MONGODB_URI provided — running in mock mode.');
}

// Start server
app.listen(PORT, () => {
  console.log(`\n🚀 Server running at http://localhost:${PORT}`);
});

Then we have a Express app called app.js that uses app method from express. Routes done by Express router method in individual files:

import express from 'express';
import cors from 'cors';
import morgan from 'morgan';
import { corsOptions } from './config/cors.js';
import authRoutes from './routes/authRoutes.js';
import adminRoutes from './routes/adminRoutes.js';
import streamRoutes from './routes/streamRoutes.js';
import healthRoutes from './routes/healthRoutes.js';

const app = express();

// Middleware
app.use(morgan('dev'));
app.use(cors(corsOptions));
app.use(express.json());

// Routes
app.use('/api/auth', authRoutes);
app.use('/api/admin', adminRoutes);
app.use('/api/streams', streamRoutes);
app.use('/health', healthRoutes);

// Root route
app.get('/', (req, res) => {
  res.send(`
    <div style="font-family: sans-serif; text-align: center; padding-top: 50px;">
      <h1>DevStream API is Online</h1>
      <p>The server is running correctly.</p>
      <p>Access your data here: <a href="/api/streams">/api/streams</a></p>
    </div>
  `);
});

// 404 handler
app.use((req, res) => {
  res.status(404).json({ error: 'Route not found' });
});

export default app;
