Introduction to Laravel

Laravel is a free open source PHP web Framework which was created by Taylor Otwell and was intended for the development of web applications following the model view controller architectural pattern which is mainly based on symfony. Some of the features of Laravel are basically a modular packaging system with a dedicated dependency manager with a varied way of accessing relational databases. Lets know more about Laravel  and some of its very famous and exciting features. All are mentioned below in this article.

Learning a new framework can sometimes feel daunting but also exciting at the same point. But, to get into a smoother transition, one must attempt to create a very clear and concise documentation for Laravel. Laravel is mainly a web application framework which is expressive and has an elegant syntax. People usually believe development must be an activity which should be enjoyed, creative and experiences which are ardently truly fulfilling. Thus, Laravel attempts to take the pain and time out of the development process by easing out the common tasks and is majorly used in the web projects such as routing, session, caching and authentication. Laravel also aims to make the development process quite pleasing one for the developer without sacrificing application functionality. As said happy developers make the best code, to this end one has attempted to combine both the very best in the frameworks including frameworks which are usually implemented in other languages as well such as Ruby on Rails, ASP.NET MVC and Sintara. Laravel is a highly accessible and powerful tool which is needed by large and robust applications. It also has an inversion of control container needing an expressive migration system and also has a tightly integrated unit with a testing support giving you the tools which one needs to build an application with which one has asked.

There are several Laravel Development Company India, knowing and constructing the details, these Laravel Development Company India, hold their research and details and are given direct instruction from the higher authorities. Every Laravel Development cCompany India, also holds a directive and legal card, which gives them the right to hire and work and then send their research by verification with a final upload or change in the software. Features of Laravel are as follows:

Bundles provided by a modular packaging system since the release of Laravel 3 with the bundled features which are already available for easy addiction to applications. Also, Laravel 4 uses composer as a dependency manager to add framework agnostic and Laravel specific PHP packages which are available from the packagist repository.

Eloquent ORM is basically an advanced PHP implementation of the active record pattern which provides at the same time the internal methods for enforcing constraints on the relationships present between database objects. Also following the active record pattern, the eloquent ORM presents the database tables as classes with their object instances tied to a single table row.

Restful controllers provide an optional way for separating the logic behind serving HTTP GET and POST requests.

Configure IdentityServer for Xamarin Forms

In this new post, I explain how to configure IdentityServer for Xamarin Forms to integrate Web Authenticator using Xamarin Essentials.

First, I wrote a post about how to implement the authentication in Xamarin Forms with IdentityServer. So, my focus was only on the Xamarin side. Here I want to explain what the IdentityServer configuration is in order to succeed in the login.

Create a new client

Have you ever wondered how hard it would be to set up a minimal viable authentication server that uses industry standards and usable from your mobile Xamarin application? Well, I have, and I believe in having found a solution that can be a great starting point and will allow you to expand the answer should you ever need to do so.

One common industry standard is OpenID / OAuth2, which provides a standardized authentication mechanism that allows user identification securely and reliably. You can think of the identity service as a web server that identifies a user and provides the client (website/mobile app, etc.) to authenticate itself with another application server that said client uses.

The recommended flow for a mobile app

While the OAuth standard is open to anyone with a computer and an internet connection, I generally do not recommend writing your own implementation. My go-to solution for setting up an identity provider is the IdentityServer.

IdentityServer4 is built based on the OAuth spec. It is built on the trusted ASP.NET Core but requires quite some know-how to get the configurations and other settings ready for use. Luckily, there is a quickstart template that you can install via the dotnet command line and then make your server. You can find the repository here on GitHub. After following the install instructions, we can create a server with the following command:

dotnet new sts -n XamarinIdentity.Auth

The solution is pretty much ready to go but let’s look at the configuration of the IdentityServer in Config.cs and make some adjustments in the GetClients method.

Add a client

Based on the template, let’s make some changes that leave us with the following final configuration:

public static IEnumerable<Client> GetClients(IConfigurationSection stsConfig) { return new List<Client> { // mobile client new Client { ClientName = "mobileclient-name-shown-in-logs", ClientId = "the-mobileclient-id-of-your-choice", AllowedGrantTypes = GrantTypes.Code, AllowOfflineAccess = true, // allow refresh tokens RequireClientSecret = false, RedirectUris = new List<string> { "oidcxamarin101:/authorized" }, PostLogoutRedirectUris = new List<string> { "oidcxamarin101:/unauthorized", }, AllowedScopes = new List<string> { "openid", "role", "profile", "email" } } }; }

Generally, you can set the ClientName, ClientId, RedirectUris and PostLogoutRedirectUris to values of your choosing. The scopes represent the defaults. Further note that by setting AllowOfflineAccess to true, the user can request refresh tokens which means that as long as the refresh token is valid, the user will not have to log in but can use said refresh token to request a new access token. In mobile apps, this is generally the prefered behaviour since users usually have their personal device and therefore expect the app to “store” their login.

As you can see, The RedirectUris and PostLogoutRedirectUris are using a custom URL oidcxamarin101:/ that identifies my app.

IdentityServer Admin

So, very often we have to create the front-end to manage users, integrate the authentication with external services suck as Facebook and Twitter, make API calls secure. IdentityServer offers a nice UI for administration but it is quite expensive. Now, I found a very nice work on GitHub: Skoruba.IdentityServer4.Admin.

This is cool! The application is written in ASP.NET Core MVC using .NET5.

Skoruba IdentityServer4 Admin UI

Add a new client

So, adding a new client with this UI is quite easy. In the IdentityServer Admin website, create a new Client. Then, the important configuration are:

Under Basic

Add this RedirectUris : oidcxamarin101:/authenticated

Allowed Grant Types: authorization_code

Under Authenticaton/Logout

Add Post Logout Redirect Uris: oidcxamarin101:/signout-callback-oidc

Basic configuration

Authentication/Logout configuration

I hope this is useful! Do you know Microsoft is releasing .NET MAUI that will replace Xamarin? Here how to test it with Visual Studio 2022.

If you have any questions, please use the Forum. Happy coding!

Repository Pattern In Asp.Net Core MVC

Repository Pattern In MVC by Sagar Jaybhay

The Repository Pattern is one of the most popular patterns to create an enterprise level application. It restricts us to work directly with the data in the application and creates new layers for database operations, business logic, and the application’s UI.

Repository pattern is abstraction of the data-access layer and it hides the details about how the data is stored, retrieve from the underlying database.

In the real-life project, it is not good idea to access database logic directly in the business logic. When you write the database logic in business logic it becomes hard to test and tough to extend further.

Direct access database logic in business logic has some serious problems:

Difficult for unit testing

When you want to test business logic you need an external dependency of an external database if you integrate logic in the same business logic file(class).

Repository pattern separates data access logic and entity which we mapped from business logic.

When we use repository pattern the domain entities like student, employee, etc and data access logic and business logic are talk to each other by using interface means by using interface we achieve loose coupling else we have tight coupling.

Advantages of Repository pattern:

Business logic tested without the need of an external database

We can separately test database access logic

Domain-driven development becomes easier

As we centralizing data access logic so maintainability increases.

Repository pattern at least has 2 participants repository class and repository interface. In repository interface all CRUD operation signature needs to be present as we implement this interface in our repository class. Now our repository only contains information which is supported by our repository but doesn’t provide the details.

Below is our repository interface.

public interface IStudentRepository Student GetStudents(int StudentID); IEnumerable<Student> GetAllStudent(); Student AddStudent(Student student); Student DeleteStudent(int studentID); Student UpdateStudent(Student student);

Now we need to implement this interface on a repository class.

Below class is in-memory database repository class where we implement the interface.

public class StudentRepo : IStudentRepository private List<Student> _students; public StudentRepo() _students = new List<Student>() new Student() Address="xyz",Division=Divi.A_10, FullName="Sagar",StudentId=1, new Student() Address="abc",Division=Divi.B_9, FullName="RAM",StudentId=2, new Student() Address="def",Division=Divi.A_8, FullName="LAKHAN",StudentId=3 ; public Student AddStudent(Student student) var studid = _students.Max(e => e.StudentId)+1; student.StudentId = studid; _students.Add(student); return student; public Student DeleteStudent(int studentID) var stud = _students.Where(e => e.StudentId == studentID).FirstOrDefault(); if (stud != null) _students.Remove(stud); return stud; public IEnumerable<Student> GetAllStudent() return this._students.AsEnumerable(); public Student GetStudents(int StudentID) return _students.Where(r=>r.StudentId==StudentID).FirstOrDefault(); public Student UpdateStudent(Student student) var stud = _students.Where(e => e.StudentId == student.StudentId).FirstOrDefault(); if (stud != null) stud.Address = student.Address; stud.FullName = student.FullName; stud.Division = student.Division; return stud;

Now you can see here this interface is capable of all CRUD operation against the student type.

For SQL server database integration we create another class which in which we implement IStudentRepository interface.

Now we create OurDbContext class which implement DbContext Interface.

public class OurDbContext:DbContext public DbSet<Student> Students get; set; public OurDbContext(DbContextOptions<OurDbContext> options):base(options)

We want to inject this class object in our repository class object so we inject this by constructor injection.

public class SQLStudentRepository:IStudentRepository private OurDbContext context; public SQLStudentRepository(OurDbContext context) this.context = context; public Student GetStudents(int StudentID) return context.Students.Find(StudentID); public IEnumerable<Student> GetAllStudent() return context.Students; public Student AddStudent(Student student) context.Students.Add(student); context.SaveChanges(); return student; public Student DeleteStudent(int studentID) var stud = context.Students.Find(studentID); if (stud != null) context.Students.Remove(stud); context.SaveChanges(); return stud; public Student UpdateStudent(Student student) var stud = context.Students.Attach(student); stud.State = EntityState.Modified; context.SaveChanges(); return student;

Now you can see we have single IStudentRepository interface which has 2 implementations. One is in-memory implementation and another is SQL Repository.

Below is home controller where we inject IStudentRepository interface into home controller. We use this injected interface in all our controller method.

Below is our home controller.

public class HomeController : Controller private IStudentRepository _repository; public HomeController(IStudentRepository repository) this._repository = repository; //[Route("")] //[Route("~/")] //[Route("[action]")] public ViewResult Index() var v = _repository.GetAllStudent(); return View(v); // [Route("[action]")] public ViewResult List() var v = _repository.GetAllStudent(); return View(v); // [Route("[action]/id?")] public ViewResult Details(int id) HmDetailsVM hmDetailsVM = new HmDetailsVM(); hmDetailsVM.student = _repository.GetStudents(id); hmDetailsVM.DivisonOfStudent = "9-A"; ViewBag.TitleNew = "Student Info"; return View(hmDetailsVM); [HttpGet] public ViewResult Create() return View(); [ActionName("CreateStudent")] [HttpPost] public IActionResult Create(Student student) if (ModelState.IsValid) var st = _repository.AddStudent(student); // return RedirectToAction("Details", new id = st.StudentId); return View("Create");

So in above controller we never mentioned anywhere which implementation we need to use so the questioned comes to your mind how controller decides which implementation we use either In-memory or SQL Repository. The answer to above questioned is we add

services.AddScoped<IStudentRepository,SQLStudentRepository>();

in our startup class ConfigureServices method.

public void ConfigureServices(IServiceCollection services) services.AddMvc(); services.AddTransient<IStudentRepository,StudentRepo>(); services.AddDbContextPool<OurDbContext>(options => options.UseSqlServer(_config.GetConnectionString("StudentDBString"))); services.AddScoped<IStudentRepository, SQLStudentRepository>();

This is method in our startup class. Difference between addscoped,addtransient and addsingleton check on this link.

مزیت اصلی این دوره؟ به جای اینکه ماه ها وقت صرف کنین تحقیق کنین، مطالعه کنین و موارد کاربردی و مهم API نویسی رو یاد بگیرین توی این دوره همشو یک جا و سریع یاد میگیرین و تو وقتتون صرفه جویی میشه. همچنین یک پله هم به Senior Developer شدن نزدیک میشین آشنایی با ASP.NET Core زبان ASP.NET Core نگارشی از .NET محسوب می شود که بر پایه .NET Core استوار است. این زبان به نوع سیستم عامل وابسته نیست و نیازی به واسط برنامه نویسی ویندوز ندارد. اگرچه ویندوز هنوز هم یکی از سیستم عامل های برتر محسوب می شود اما نرم افزار های تحت وب روز به روز اهمیت و کاربرد بیشتری پیدا می کنند. شرکت مایکروسافت به منظور گسترش حوزه کارکرد .NET زبان ASP.NET Core را معرفی کرد است. به این معنی که نرم افزار های ایجاد شده با ASP.NET Core می توانند در محیط های مختلفی میزبانی شوند. زبان ASP.NET Core برخلاف MVC نخستین، ارتباطی با پروژه های وب فرم ندارد و در مقایسه با MVC نخستین، بسیار ساده تر شده است. و به دلیل این که ASP.NET Core مبتنی بر فریم ورک .NET Core می باشد، می توان با استفاده از آن پروژه های وب مختلفی که قابلیت میزبانی در محیط های مختلف و سیستم عامل های گوناگون داشته باشد، را ایجاد کرد. 📷 ASP.NET Core چیست ؟ ASP.NET Core یک فریم ورک جدید برای ساخت برنامه مدرن همچون برنامه های تحت وب و برنامه های موبایلی می باشد که توسط شرکت مایکروسافت ارائه شده است. برنامه های نوشته شده با این فریم ورک قابلیت اجرا شدن در ویندوز، لینوکس و مک را دارند. این فریم ورک ویژگی های Web API و MVC را به فریم ورک برنامه نویسی وب متصل می سازد. ASP.NET Core 1.0 یک باز نویسی از فریم ورک فعلی ASP.NET 4.6 است که تقریبا قابلیت های یکسانی با نسخه ۴٫۶ دارد اما بسیار سبک تر و ماژولارتر است. منظور از Cross Platform این است که برنامه های ایجاد شده می توانند بر روی چندین پلتفرم اجرا شوند. برنامه های ASP.NET Core هم بر روی .NET Core و .NetFramework اجرا می شوند. این تکنولوژی با هدف بهینه سازی فریم ورک های مبتنی بر محاسبات ابری پیاده سازی شده است که میزان بار اضافی بر روی سرور را بسیار کاهش می دهد. این تکنولوژی باعث می شود تا در زمان طراحی و پیاده سازی میزان انعطاف پذیری برنامه های توسعه دهندگان افزایش یابد. چرا ASP.NET Core ؟ در لیست زیر برخی از مهم ترین ویژگی های فریم ورک ASP.NET Core را مشاهده می کنید: - متن باز و رایگان - Cross Platform - سبک، قدرتمند و ساده - امکان دسترسی به محیط محاسبات ابری - ارتقاء سطح ماژولار بودن - پشتیبانی و سازگاری کامل با NuGet Package - یکپارچه سازی فریم ورک های سمت کاربر مدرن و BackEnd - و سایر موارد فهرست سرفصل ها و رئوس مطالب مطرح شده در این مجموعه آموزشی - لایه بندی اصولی پروژه (Project Layering and Architecture)  : در این دوره لایه بندی اصولی یک پروژه را از ابتدا شروع و هر بخش را بررسی می کنیم. همچنین مباحث Repository و UOW رو هم بررسی می کنیم. - احراز هویت (Authentication) - ASP.NET Core Identity  : احراز هویت توسط Identity + سفارشی سازی - (Json Web Token) JWT  : احراز هویت توسط Jwt + یکپارچه سازی آن با Identity - (Json Web Encryption) JWE  : ایمن سازی توکن ها بوسیله  رمزنگاری توکن (JWE) - Security Stamp : جلوگیری از اعتبارسنجی توکن به هنگام تغییر دسترسی های کاربر جهت امنیت بیشتر - Claims : کار با Claim ها و تولید خودکار آنها توسط ClaimsFactory - Logging (ثبت خطا ها) - Elmah : استفاده از Elmah برای لاگ خطا ها در Memory, XML File و Database - NLog : استفاده از NLog برای لاگ خطا ها در File و Console - Custom Middleware  : نوشتن یک میدلویر سفارشی جهت لاگ تمامی خطا (Exception) ها - Custom Exception  : نوشتن Exception برای مدیریت ساده تر خطا ها - Sentry : ثبت خطا ها در سیستم مدیریت لاگ sentry.io (مناسب برای پروژه های بزرگ) - تزریق وابستگی (Dependency Injection ) - ASP.NET Core IOC Container  : استفاده از Ioc container داخلی Asp Core - Autofac : استفاده از محبوب ترین کتابخانه  Autofac (Ioc Container) - Auto Registeration  : ثبت خودکار سرویس ها توسط یک تکنیک خلاقانه با کمک Autofac - ارتباط با دیتابیس (Data Access) - Entity Framework Core  : استفاده از EF Core - Auto Entity Registration  : ثبت Entity های DbContext به صورت خودکار توسط Reflection - Pluralizing Table Name  : جمع بندی نام جداول EF Core به صورت خودکار توسط کتابخانه Pluralize.NET و Reflection - Automatic Configuration  : اعمال کانفیگ های EntityTypeConfiguration (FluentApi) به صورت خودکار توسط Reflection - Sequential Guid  : بهینه سازی مقدار دهی identity برای Guid به صورت خودکار توسط Reflection - Repository : توضیحاتی در مورد معماری اصولی Repository در EF Core - Data Intitializer  : یک معماری اصولی برای Seed کردن مقادیر اولیه به Database - Auto Migrate : آپدیت Database به آخرین Migration به صورت خودکار - Clean String : اصلاح و یک دست سازی حروف "ی" و "ک" عربی به فارسی و encoding اعداد فارسی در DbContext به صورت خودکار به هنگام SaveChanges - Versioning : نسخه بندی و مدیریت نسخه های پروژه + سفارشی سازی و ایجاد یک معماری حرفه ای - ابزار (Swashbuckle) Swagger - Swagger UI : ساخت یک ظاهر شکیل به همراه داکیومنت Aciton ها و Controller های پروژه و امکان تست API ها توسط Swagger UI - Versioning : یکپارچه سازی اصولی Swagger با سیستم نسخه گذاری (Versioning) - JWT Authentication  : یکپارچه سازی Swagger با سیستم احراز هویت بر اساس Jwt - OAuth Authentication  : یکپارچه سازی Swagger با سیستم احراز هویت بر اساس OAuth - Auto Summary Document Generation  : تولید خودکار داکیومنت (توضیحات) برای API های پروژه - Advanced Customization  : سفارشی سازی های پیشرفته در Swagger - دیگر قابلیت ها - API Standard Resulting  : استاندارد سازی و یک دست سازی خروجی API ها توسط ActionFilter - Automatic Model Validation  : اعتبار سنجی خودکار - AutoMapper : جهت Mapping اشیاء توسط کتابخانه محبوب AutoMapper - Auto Mapping : سفارشی سازی وایجاد  یک معماری حرفه ای  برای Mapping اشیا توسط Reflection - Generic Controller  : ساخت کنترلر برای عملیات CRUD بدون کد نویسی توسط ارث بری از CrudController - Site Setting : مدیریت تنظیمات پروژ توسط Configuration و ISnapshotOptions - Postman : آشنایی و کار با Postman جهت تست API ها - Minimal Mvc : حذف سرویس های اضافه MVC برای افزایش پرفرمنس در API نویسی - Best Practices : اعمال Best Practices ها جهت بهینه سازی، افزایش پرفرمنس و کدنویسی تمیز و اصولی - و چندین نکته مفید دیگر ...
