STEP 3: Create your server.js file

server.js

const express = require('express');
const app = express();
const port = 3300;

app.get('/message', function (req, res) {
     res.send('This is the message');
});

app.get('/media', function (req, res) {
var response = {
  
podcasts: [{
       "description": "some text",
       "id": 574,
       "title": "Why long-term value is a winning bet",
       "media": "podcast",
       "publishedDate": "2018-12-19T18:00:00.000Z",
       "isLive": true,
       "isDeleted": false,
       "link": "https://podcasts.com/574",
       "createdAt": "2018-12-20T06:30:00.618Z",
       "updatedAt": "2019-01-31T06:30:00.864Z"
    }],
 total: 1
}

if (response.podcasts.length > 0) {
     res.send(response);
} else {
  
var errorObj = {
     httpCode: 404,
     message: 'NOT_FOUND',
     description: 'The resource referenced by request does not exists.',
     details: 'Podcast is not available'
}

   res.status(404);
   res.send(errorObj)
 }
});

app.listen(port, function () {
   console.log("\nServer is running on port " + port);
});

module.exports = app; // for testing
