Express Router unable to route to another folder

Question

I am trying to create a Node JS app with mongoDB. from main app.js I am trying to redirect to another folder named "services". Here is my folder structure -

Here is my app.js -

const express = require('express')
const mongoose = require('mongoose')
const dotenv = require('dotenv')
const cors = require('cors')
const bodyParser = require('body-parser')
const app = express()
const users = require('./userSchema')
const services = require('./services/index')
app.use('/services', express.static('/services'))
app.use(express.static('/'));
app.use(cors())
dotenv.config()
const port = 3000

mongoose.connect(process.env.DB_CONNECT,
    {
        useUnifiedTopology: true,
        useNewUrlParser: true,
        useFindAndModify: false
    })
    .then(() => console.log('Connected to mongoDB'))
    .catch(err => console.error('Could not connect to MongoDB..', err))
const jsonParser = bodyParser.json()

app.get('/allName', async (req, res) => {
    let data = await users.find()
    res.status(200).send(data)
})
app.listen(port, () => console.log(`Demo app listening on port ${port}!`))

Here is my index.js file inside services folder -

var express = require('express')
var router = express.Router()
router.get('/', function (req, res) {
  res.send('Birds home page')
})

router.get('/about', function (req, res) {
  res.send('About birds')
})

module.exports = router

While running http://localhost:3000/allName , it is working fine. But if i try to run http://localhost:3000/services, it is throwing Cannot GET /services. I am not able to fix this.

How to redirect to index.js from app.js when users trigger http://localhost:3000/services?

try URL: http://localhost:3000/services/index.js – Chuong Tran Feb 06 '20 at 11:08 — Chuong Tran, Feb 06 '20 at 11:08

change

app.use('/services', express.static('/services'))

into

app.use('/services', services);

express.static is used to serve static files, looks like you wish to use a router and not return static files. This is why the server does not respond as you like

Yes, because you haven't properly added the reference of the service routes.
Remove express.static from the reference because you already have imported the service routes in a variable then just use it and it will work as expected. Just a note. Express.static is used to load/use the static files like css or images or something like that. Check the code below.

const express = require('express')
const mongoose = require('mongoose')
const dotenv = require('dotenv')
const cors = require('cors')
const bodyParser = require('body-parser')
const app = express()
const users = require('./userSchema')
const services = require('./services/index')
**app.use('/services', services)** // change this into your code.
app.use(express.static('/'));
app.use(cors())
dotenv.config()
const port = 3000

mongoose.connect(process.env.DB_CONNECT,
    {
        useUnifiedTopology: true,
        useNewUrlParser: true,
        useFindAndModify: false
    })
    .then(() => console.log('Connected to mongoDB'))
    .catch(err => console.error('Could not connect to MongoDB..', err))
const jsonParser = bodyParser.json()

app.get('/allName', async (req, res) => {
    let data = await users.find()
    res.status(200).send(data)
})
app.listen(port, () => console.log(`Demo app listening on port ${port}!`))

It's working. Thanks. I can't mark multiple as Accepted Answer — Rituparno Bhattacharya, Feb 06 '20 at 12:09
