Art Of Engineer: .NET Core Web API + Vue JS + Microsoft SQL

Hello every one, In this tutorial, you will learn how to create a full stack web application from scratch using Microsoft SQL server for the database, .NET Core Web API for the backend, and Vue JS for the front end.

We will first start with creating the necessary tables in Microsoft SQL server, then create the Web API project with the required rest API end points. Finally we will use Vue JS for creating the front end.

You will learn how to add routing for our app.

Create bootstrap table with custom sorting and filtering capabilities.

Add modal pop up windows with drop downs and date pickers.

We will also learn how to upload an image and store it in the backend server.

Lets first create the database tables required for our app.

We need two tables for our app.

One to store department details and another one to store employee details.

Lets start with department table.

This table will have two fields.

One to store an autogenerated table id, and another one to store the department name.

CREATE TABLE [dbo].[Department](
	[DepartmentId] [int] IDENTITY(1,1),
	[DepartmentName] [nvarchar](500)
)

Lets insert some records using insert query.

INSERT into [dbo].[Department] ([DepartmentName]) VALUES ('IT')
INSERT into [dbo].[Department] ([DepartmentName]) VALUES ('Support')

Now lets check the data in our table using select query.

select * from [dbo].[Department]

Let us similarly create table to store employee details.

We will be storing employee id, employee name, department to which the employee belongs to, the date of joining and also the uploaded profile picture file name.

CREATE TABLE [dbo].[Employee](
	[EmployeeId] [int] IDENTITY(1,1) ,
	[EmployeeName] [nvarchar](500) ,
	[Department] [nvarchar](500) ,
	[DateOfJoining] [datetime] ,
	[PhotoFileName] [nvarchar](500) 
)

INSERT into [dbo].[Employee] ([EmployeeName], [Department], [DateOfJoining], [PhotoFileName]) VALUES ('Bob', 'IT', '2021-06-17', 'anonymous.png')

Lets create the dot net core web API project.

-> Lets open up visual studio first.

-> Click on create a new project.

-> Choose ASP dot net core Web API .

->Choose appropriate folder.

->We might not need HTTPS for now.

Now lets take a look at some of the important files in the project.

-> All the dependencies and packages needed for our app can be found in the dependencies folder.

-> launchSettings.json file contains the details of how the project should be started.

-> Controllers folders contains controllers in which we write our API methods.

-> We generally keep the configuration details such as database details in appSettings.json.

-> The program.cs contains the Main() program which is the entry point of our app.

-> Also it creates web host which basically helps the app to listen to http requests.

-> The startup class configures all the services needed for our app. Services are basically reusable components that can be used across our app using dependency

Injection. It also contains the configure method which creates our app’s request processing pipeline.

We need to make a couple of changes in startup class.

One is to enable the CORS.

By default, all web API projects come with a security which blocks requests coming from different domains. We are basically writing instructions to disable that security and allow the requests to be served.

We are also making one more change to the serializer class to keep the json serializer as our default.

We might need to install a nuget package to do this.

Startup.cs Complete code:

using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.AspNetCore.Mvc;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting;
using Microsoft.Extensions.Logging;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using Newtonsoft.Json.Serialization;
using Microsoft.Extensions.FileProviders;
using System.IO;

namespace WebApplication1
{
    public class Startup
    {
        public Startup(IConfiguration configuration)
        {
            Configuration = configuration;
        }

        public IConfiguration Configuration { get; }

        // This method gets called by the runtime. Use this method to add services to the container.
        public void ConfigureServices(IServiceCollection services)
        {
            //Enable CORS
            services.AddCors(c =>
            {
                c.AddPolicy("AllowOrigin", options => options.AllowAnyOrigin().AllowAnyMethod().AllowAnyHeader());
            });


            //JSON Serializer
            services.AddControllersWithViews().AddNewtonsoftJson(options =>
            options.SerializerSettings.ReferenceLoopHandling = Newtonsoft.Json.ReferenceLoopHandling.Ignore)
                .AddNewtonsoftJson(options => options.SerializerSettings.ContractResolver
                = new DefaultContractResolver());

            services.AddControllers();
        }

        // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
        public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
        {
            //Enable CORS
            app.UseCors(options => options.AllowAnyOrigin().AllowAnyMethod().AllowAnyHeader());

            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
            }

            app.UseRouting();

            app.UseAuthorization();

            app.UseEndpoints(endpoints =>
            {
                endpoints.MapControllers();
            });

            app.UseStaticFiles(new StaticFileOptions
            {
                FileProvider = new PhysicalFileProvider(
                   Path.Combine(Directory.GetCurrentDirectory(), "Photos")),
                RequestPath = "/Photos"
            });
        }
    }
}

The below code in startup.cs is basically to use the folder 'Photos' for image uploads.

 app.UseStaticFiles(new StaticFileOptions
            {
                FileProvider = new PhysicalFileProvider(
                   Path.Combine(Directory.GetCurrentDirectory(), "Photos")),
                RequestPath = "/Photos"
            });

Please also add a folder with name 'Photos'.

To work with SQL server, please also add below nuget package.



Next, add the models.

Department.cs:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;

namespace WebApplication1.Models
{
    public class Department
    {
        public int DepartmentId { get; set; }

        public string DepartmentName { get; set; }
    }
}

Employee.cs:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;

namespace WebApplication1.Models
{
    public class Employee
    {
        public int EmployeeId { get; set; }
        public string EmployeeName {get; set; }
        public string Department { get; set; }

        public string DateOfJoining { get; set; }

        public string  PhotoFileName { get; set; }
    }
}

Next, add the connection string in appSettings.json file.

Finally add two controllers.

DepartmentController.cs:

using Microsoft.AspNetCore.Http;
using Microsoft.AspNetCore.Mvc;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using System.Data;
using System.Data.SqlClient;
using Microsoft.Extensions.Configuration;
using WebApplication1.Models;

    public class DepartmentController : ControllerBase
    {

        private readonly IConfiguration _configuration;
        public DepartmentController(IConfiguration configuration)
        {
            _configuration = configuration;
        }

                            ";

            DataTable table = new DataTable();
            string sqlDataSource = _configuration.GetConnectionString("EmployeeAppCon");
            SqlDataReader myReader;
            using(SqlConnection myCon=new SqlConnection(sqlDataSource))
            {
                myCon.Open();
                using(SqlCommand myCommand=new SqlCommand(query, myCon))

                }
            }

            return new JsonResult(table);
        }

        [HttpPost]
        public JsonResult Post(Department dep)
        {
            string query = @"

            DataTable table = new DataTable();
