Building Clean Architecture Application using ASP.NET Core Web API and Angular 11 — Backend
In this article, we are going to learn building a Clean Architecture application using ASP.NET Core Web API and Angular 11 Front End.
Building an ASP.NET Core WebAPI using Clean Architecture
- ASP.NET Core 3.1 Web API.
- API Versioning
- Swagger UI.
- JWT Token Authentication
- Global Error Handler Middleware
- CQRS ( Command Query Responsibility Segregation)
- NHibernate ORM
- Generic Repository Pattern
- Fluent Validation
You can refer to the below GitHub project for complete implementation.
Clean Architecture Application Design from Scratch using Dotnet Core 3.1 WebApi and Angular 11 FrontEnd …
The architecture defines where the application performs its core functionality and how that functionality interacts with things like the database and the user interface. Clean architecture refers to organizing the project so that it’s easy to understand and easy to change as the project grows.
Command Query Responsibility Segregation is a design pattern to separate the read and write processes of your application. Read operations are called Queries and write operations are called Commands.
Swagger UI Setup
The swagger object model and middleware exposes the JSON objects as Endpoints
Installing Swagger packages using NuGet package console with the below command.
Install-Package Swashbuckle.AspNetCore -Version 5.6.3
Swagger Configuration with Bearer token Authentication
JWT Token Implementation
The JWT Bearer Token is used for accessing the WebApi endpoints securely. Below is the JWT configuration
Token Generation On Successful Login
Global Error Middleware
Server Internal Error Exceptions and Business Validation Exceptions are handled and the response is returned for use of displaying these validations in UI.
NHibernate ORM and Generic Repository Pattern
NHibernate is used to interact with the database. Singleton Session factory is implemented. Below is the Persistence Layer Service Extension.
<PackageReference Include=”FluentValidation.DependencyInjectionExtensions” Version=”9.3.0" />
To define a set of validation rules for a particular object, you will need to create a class that inherits from AbstractValidator<T>, where T is the type of class that you wish to validate.
Below is the sample Create User Validations.
