.Net Core 3.1 Web API Enterprise Application Architecture

This is a complete architecture to support enterprise application. Following things are implemented in this architecture.

• NLog
• Store Procedure
• Linq Query
• JWT
• SignalR
• Swagger
• Generic Repository
• Generic Store Procedure Call
• Unit of work

---

Swagger Example:

Swagger API Explaination:

• Login: This method returns a JWT token. Role authentication can also be done just need to change

[Authorize] to [Authorize(Role="RoleId Entered in JWT")] in controller.

• DecodeToken: This method decode token, use to identity user and it provide security to application.Eample: Roleid is encoded in tokens so if hacker changes the token he/she will be unauthorized.

If user need his family member name so he is only sending a GET request and token.We will decode token at run time and use his Roldid(Encoded in JWT token) to idetitfy user

• DataFromLinqQuery: Returns data using linq query and entity Framework.

• DataFromSP: Returns data using Store Procedure and Enitity Framework.

# HOW TO WORK IN PROJECT:

1. Add Controller
2. Add Service and Interface in Services project.

Don't forget to register service in servicemodule.cs Example: services.AddTransient<ITestService, TestService>();

3. Add Unit of work into service file using dependency injection. ` private readonly IUnitOfWork _unitOfWork; private readonly AppSettings _appSettings;

    public TestService(IUnitOfWork unitOfWork, IOptions<AppSettings> appSettings)
    {
        _unitOfWork = unitOfWork;
        _appSettings = appSettings.Value;
    }`
   

4. User unit of work to use Linq or Store Procedure.

Linq:

public TestTable DbLinq() { var userRepository = _unitOfWork.GetRepository<TestTable>(); int a = 2; var user = userRepository.GetAll().Where(c => c.ID == a).SingleOrDefault(); if (user == null) return null; return user; }

Store Procedure

public TestTable SpQuery() { var id = new SqlParameter("@UserId", SqlDbType.Int) { Value = 2 }; return _unitOfWork.SpRepository<TestTable>("testSP @UserId", id).SingleOrDefault(); }

5. Make Models in TwinCityCoders.Models project and add dbset in DatabaseContext.cs file. public DbSet<TestTable> TestTables { get; set; }

Thats it !!
