TypeError: Cannot read property 'get' of undefined. Is npm the issue?

Question

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

router.get('/', function(req, res, next){
res.send('INDEX PAGE');
});

module.exports = router;

I keep getting this error, I've even downgraded my express to V3.21.

TypeError: Cannot read property 'get' of undefined

Answer 1

The Express V3.X API reference doesn't have express.Router. API Reference

Answer 2

Do this instead

var express = require('express');
var app= express();

app.get('/', function(req, res, next){
res.send('INDEX PAGE');
});

module.exports = app;
