Postman: Connect ECONNREFUSED 127.0.0.1:5005-CodePudding

I have developed an API endpoint. It was working fine before. Unfortunately the project folder got corrupted (I recreated the files db.js and server.js). But now when I try to fetch data from API, I'm getting:

"connect ECONNREFUSED 127.0.0.1:5005"

The URL I'm using is localhost:

And my server is running on the same port i.e. 5005:

Can someone please elaborate what can be the problem? My hunch is that when I recreated the files I may have missed something:

db.js:

const mongoose = require('mongoose');

const userName = "myUsername"
const password = "myPassword"
const dbName = "comfyRooms"

const dbURL = `mongodb srv://${userName}:${password}@mongo-cluster.damzf.mongodb.net/${dbName}?authSource=admin&replicaSet=atlas-s7z01e-shard-0&readPreference=primary&appname=MongoDB Compass&ssl=true`

mongoose.connect(dbURL, {useUnifiedTopology: true, useNewUrlParser: true})
let connection = mongoose.connection

connection.on('error', () => {
    console.log('Unable to connect to MongoDB')
})

connection.on('connected', () => {
    console.log("MongoDB connection established :)")
})

module.exports = mongoose

server.js

const express = require('express')
const app = express()

const dbConfig = require('./db')
const roomsRoute = require('./routes/roomsRoute')

app.use('/api/rooms', roomsRoute)

const port = process.env.PORT || 5005

app.listen(() => {
    console.log("Node JS server listening on port "   port)
})

roomsRoute.js:

const express = require('express');
const router = express.Router();

const Room = require('../models/rooms');

router.get('/getallrooms', async (req, res) => {
    try {
        const rooms = await Room.find({});
        return res.send(rooms);
    } catch (error) {
        return res.status(400).json({message: error});
    }
});

module.exports = router;

I have attached the important files. Please let me know if any other information is missing. Thanks!

CodePudding user response：

You are not passing the port variable to the listen function, you are just logging it

app.listen(() => {
console.log("Node JS server listening on port "   port)
})

This should work

app.listen(port, () => {
  console.log("Node JS server listening on port "   port)
})
