express js api end point does not work on azure web app

Question

I just tried creating a test api app using Express js. i embraced many ways available on internet to deploy and run node js api app. But nothing is working in my case. Please help me.

Other wise i will have to leave either azure or node js.

I am attaching all the files below: 1.index.js

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


router.get('/things', function(req, res) {
    res.json('GET route on things.');
});
router.post('/things', function(req, res) {
    res.json('POST route on things.');
});

app.get('/hello', function(req, res) {
    res.json("Hello World!");
});

app.post('/hello', function(req, res) {
    res.json("You just called the post method at '/hello'!\n");
});

const port = process.env.PORT || 1337;
app.listen(port);

Answer 1

This would work if you change it to:

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

//****************************************
app.route('/things')
    .get(function (req, res) {
        res.json('GET route on things.');
    })
    .post(function (req, res) {
        res.json('POST route on things.');
    })
//****************************************
// or
//****************************************
var router = express.Router();
router.get('/', function (req, res) {
    res.json('GET route on things.');
});
router.post('/', function (req, res) {
    res.json('POST route on things.');
});
app.use('/things', router);
//****************************************

app.get('/hello', function (req, res) {
    res.json("Hello World!");
});

app.post('/hello', function (req, res) {
    res.json("You just called the post method at '/hello'!\n");
});

const port = process.env.PORT || 1337;
app.listen(port);

The app will now be able to handle requests to:

• GET /things
• POST /things
• GET /hello
• POST /hello

Answer 2

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

router.get('/things', function(req, res) {
    res.json('GET route on things.');
});
router.post('/things', function(req, res) {
    res.json('POST route on things.');
});

app.get('/hello', function(req, res) {
    res.json("Hello World!");
});

app.post('/hello', function(req, res) {
    res.json("You just called the post method at '/hello'!\n");
});

const port = process.env.PORT || 1337;
app.listen(port);
