I am struggling with setting up an Express JS router.
I am facing difficulty passing req and res to my class method.
Not Working app.get('/', controller.index)
Working
app.get('/', (res,req) => controller.index(req,res)The routing flow I implemented follows this path:
app.js (Main file) > /routes/index.js > /routes/user.route.js > /controllers/user.controller.js > /services/user.services.js
app.js
import express from 'express';
import cors from 'cors';
import routes from './routes';
import db from './models';
import dotenv from 'dotenv';
dotenv.config();
const app = express();
const port = process.env.PORT || 3001;
app.use(cors())
app.use(express.json());
app.use(express.urlencoded({ extended: false }));
// Database Initialize
db.sequelize.sync()
.then(() => {
console.log("🚀 Database Connected.");
}).catch((err) => {
console.log("❌ Failed Connect to Database");
})
// Router
app.use(routes);
//global dir
global.__basedir = __dirname;
app.enable("trust proxy");
app.listen(port, () => {
// logger.info("Checking the API status: Everything is OK");
console.log(`🚀 App listening on port ${port}`);
})

I attempted changing const app = express() and const app = express.Router() but the issue persists.
