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?
Today we'll split our application logic following the CQRS Design Pattern.
Then, we'll introduce the package MediatR which will play nicely with this Design Pattern and help us split our logic by feature, which will make the use cases in our application layer clear.
Give MediatR a ⭐:
