What is this series?
We'll build a REST API following Clean Architecture & Domain-Driven Design principles completely from scratch.
We will use .NET 6, EF Core, and common patterns such as CQRS, unit of work, repository, mediator, and more 💪🏽
We'll also use some awesome open-source libraries such as MediatR, FluentValidation, ErrorOr, Throw, Mapster, and more.
The developing environment will be visual studio code & dotnet CLI only. We will use awesome vscode plugins for everything from sending HTTP requests to connecting to our SQL database, debugging, and peeking at JWT tokens.
We will code and refactor multiple times to tackle the many concepts I want to teach. When the series will be over, you'll have a good understanding and intuition on how to use these patterns & libraries in your industry-level applications.
How often will a new part come out?
Once or twice a week.
What are we doing today?
We'll dive into Global Error Handling using the following approaches:
1. Error Handling Middleware
2. Exception Filter Attribute
3. UseExceptionHandler middleware & "error" endpoint
We'll learn about the Problem Details error model specification & how to use it in ASP.NET.
We'll even dive into the ASP.NET's source code & understand the magic behind the Problem method in the ControllerBase and then we'll create a custom ProblemDetailsFactory which will allow us to customize the problem details response.
