Node JS service using MSSQL server.


Here I will explain how to connect sql database in node js service.
you can call this service from angular js, jquery etc.

we require express and mssql packages for this.

 First of all we attach require packages. you have download this packages using npm in your project. 

var express = require('express'),
    app = express();
var sql = require('mssql');

Then after configure your database credentials.

var config = {
    user: 'USERNAME',
    password: 'PASSSWORD',
    server: 'SERVER IP', 
    database: 'DBNAME',
    pool: {
        max: 100,
        min: 0,
        idleTimeoutMillis: 3000000
    },
    options: {
        encrypt: true
    }
};






Here I have created object of sql connection and call connect method of this.





var connection = new sql.Connection(config);
connection.connect();








here i have created get method.





app.get('/Your service name', function (req, res) {
    
    //attach header for cross platform request
    res.header("Access-Control-Allow-Origin", "*");
    res.header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");
    //add your parameter here
    var par1 = req.param('par1');
    var par2 = req.param('par2');
    var par3 = req.param('par3');
    new sql.Request(connection)
    .input('par1', sql.VarChar(50), par1)
    .input('par2', sql.VarChar(50), par2)
    .input('par3', sql.VarChar(50), par3)
    .execute('Your stored procedure name').then(function (recordsets) {
        res.send(recordsets);
        res.end();
    }).catch(function (err) {
        console.log(err);
    });
})








This service is run on 6248 port on local server.





var server = app.listen(6248, function () {
    console.log('Server Run On 6248 Port');
});

How To Deploy .net Core Application On Linux




























Here, I can explain steps to deploy .net core application on linux machine. Step 1 - Publish your .net Core application: First, create a .net core application on VS; you can make an MVC project or Web API project and if you already have an existing project, then open it. Right Click on your project Click on publish Now create a new publish profile, and browse the folder where you want to publish your project dll Click on publish so it will create your dll in the folder Step 2 - Install required .net Module on Linux: Now we have our web application dll and now we need to host it on the Linux environment. First, we need to understand how the deployment works in Linux. .Net applications run on Kestrel servers and we run Apache or Nginx server in Linux environments, which acts as a proxy server and handles the traffic from outside the machine and redirects it to the Kestrel server so we will have Apache or Nginx server as the middle layer. In this article, we will use Apache as a proxy ser...

How to write Unit Tests in .net




























Unit tests are automated tests that verify the behavior code like methods and functions. Writing unit tests is crucial to clean coding, as they help ensure your code works as intended and catches bugs early in the development process. I can share some tips for writing effective unit tests:    Write tests for all public methods Every public method in your code should have a corresponding unit test. This helps ensure that your code behaves correctly and catches any unexpected behavior early. public class Calculator {     public int Add(int a, int b) {         return a + b;     } } [TestClass] public class CalculatorTests {     [TestMethod]     public void Add_ShouldReturnCorrectSum() {         // Arrange         Calculator calculator = new Calculator();         int a = 1;         int b = 2;         // Act         int result = calculator.Add(a, b);         // Assert         Assert.AreEqual(3, result);     } }     Test boundary conditions   Make sure to test boundary conditions, such a...
