Demonstration of GET method using NodeJS and ExpressJS to find all records

In the below code, we will find an example that demonstrates the use of GET method using NodeJS and ExpressJS to find all records

//add the express module
var express = require('express');

//create an instance of express module
var app = express();

//prepare the Employee data source/model
var employees =
[
   {
   "EmployeeID" :1 ,
   "EmployeeName" : "RNA Team",
   "Salary" : "200000",
   "Address" : "Bangalore"
   },
   {
   "EmployeeID" :2 ,
   "EmployeeName" : "Mahesh Samabesh",
   "Salary" : "100000",
   "Address" : "Hydrabad"
   },
   {
   "EmployeeID" :3 ,
   "EmployeeName" : "Rui Figo",
   "Salary" : "50000",
   "Address" : "Dallas"
   },
   {
   "EmployeeID" :4 ,
   "EmployeeName" : "Indradev Jana",
   "Salary" : "456789",
   "Address" : "Los Angles"
   },
   {
   "EmployeeID" :5 ,
   "EmployeeName" : "Suresh Shailesh",
   "Salary" : "1234567",
   "Address" : "Patna"
   }
 ];

//Get the Employee records
app.get('/', function (req, res) {
  res.send(employees);
});

  //run the server
  var server = app.listen(3000, function () {
  var host = server.address().address;
  var port = server.address().port;

  console.log('Server started and is listening at :> http://%s:%s', host, port);
});

In the beginning, we have imported the needed modules and prepared the model data.Since express routes are based on HTTP verbs, so the app.get() method fetches the records from the URI specified.And finally the app starts a server and listens on port 3000 for connection. It will respond with the Employee Records for requests to the root URL (/) or route.
