Demonstration of PUT method using NodeJS and ExpressJS

In the below code, we will find an example that demonstrates the use of PUT method using NodeJS and ExpressJS

//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"
   }
 ];


//update Employee Record
app.get('/:EmployeeID/:Salary/:Address', function (req, res) {
  
  var employeeID = req.params.EmployeeID; 
  var employeeSalary =  req.params.Salary; 
  var employeeAddress = req.params.Address;
  console.log(employeeID + "-------" + employeeSalary +"--------" + employeeAddress);

  //Get Employee Records whose EmployeeID = get the EmployeeID at runtime 

    for(var i= 0; i< employees.length; i++){

      if(employees[i].EmployeeID == employeeID){

        employees[i].Salary = employeeSalary;
        employees[i].Address = employeeAddress;                
      }
    } //end Loop    
    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);
});
