Overview

This repository contains a monolithic StackOverflow-like application built with .NET Core. The project implements Domain-Driven Design (DDD) and Command Query Responsibility Segregation (CQRS) principles, leveraging MediatR for request/response handling and ProblemDetails for standardized error responses.

Architecture

The architecture of this StackOverflow clone is designed for scalability, maintainability, and testability. It includes the following components:

Layers

Domain Layer

• Contains the core business logic and domain entities.
• Implements DDD principles to model the business domain.

Application Layer

• Implements CQRS principles by segregating commands (writes) and queries (reads).
• Uses MediatR to handle commands and queries.

Infrastructure Layer

• Handles data persistence and external service integrations.
• Configures the database context and repositories.

Presentation Layer

• Exposes APIs for interaction with the application.
• Uses ProblemDetails for standardized error responses.

Key Patterns and Technologies

• .NET Core: The primary framework for building the application.
• DDD (Domain-Driven Design): Provides a structured approach to designing the system by modeling the business domain.
• CQRS (Command Query Responsibility Segregation): Segregates read and write operations to optimize performance and scalability.
• MediatR: Implements the mediator pattern for handling requests and notifications within the services.
• ProblemDetails: Provides a standardized way to handle and return error responses.

Getting Started

To get started with the StackOverflow clone, follow these steps:

Prerequisites

Ensure you have the following installed on your machine:

• .NET Core SDK
• SQL Server or any other supported database

Installation

1. Clone the repository:

   git clone https://github.com/MustafaTark/QuestionsCommunity.git

2. Navigate to the project directory:

   cd stackoverflow-clone

3. Update the database connection string in appsettings.json:

   "ConnectionStrings": {
       "DefaultConnection": "Server=your_server;Database=your_database;User Id=your_user;Password=your_password;"
   }

4. Apply database migrations:

   dotnet ef database update

5. Build and run the application:

   dotnet run

Running the Application

Once the application is up and running, you can access it via http://localhost:5000 (or the port configured in your setup).
