ASP.NET 6 REST API Following CLEAN ARCHITECTURE & DDD Tutorial | Part 1 - Project Setup

Follow me on 'em socials:

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 set up the 5 projects following Clean Architecture, use some cool vscode extensions & start setting up some authentication stuff. We'll also understand how each layer registers its own dependencies in the dependency injection IoC.

I think I can be called "Youtube/Video tutorials veteran watcher" with more than a decade experience, and sir, allow me to tell you that you are right there at the summit amongst the best instructors I've ever met. Top-top-top class.

I liked and subscribed within 15 minutes of watching this video.

I'm a professional full stack dev since more than 20 years, I'm already into what you are going to explain in these video series but I think it's always good to listen and see how other devs work out there because, as yourself said, we are always learning all the time!
IMO a good developer never sticks to a DOGMA and never follows what other people consider a creed but instead challenge himself trying to sharpen his tools and shape his ideas, often even radically changing them, about how to architecture a system and experience on real projects gives lot of input about that.
At some point any dev will realise there is no silver bullet and each problem has lot of way to accomplish its goals, it's a matter of trading between a lot of aspects like team skills, available time, habits, current company technology stack, experience, etc...
But it's always GOLD to know as many strategical and tactical patterns out there so that one can make use of the "right" tool for the current job.
I like your way to explain because as a veteran I don't like to watch videos that spend a lot of time about basic stuff, maybe your audience target will narrow a bit but personally I like it.
I'll follow you along your path to see how you tackle most advanced and debated subjects (e.g. DDD serialization, repository pattern, CQRS, eventual event sourcing, docker & containerization, microservices and so on)
Good luck, you'll need a lot of time to do what you are aiming for!

What I really liked about the video is the work methodology that's inspired: work in small increments and test that everything works before you begin adding too much code that when it doesn't run you can't be sure what exactly is wrong, is it your code or is it something else, or find out that you have to refactor a lot because you missed a step like setting up something in infrastructure. And I think the explanations are simple enough that all junior level programmers should be able to understand.

You're one of the fewer people in YouTube that can explains clear architecture so well, and better, with hands-on. For sure you deserve much more subscribers that you have! Great job, Amichai!

[drenigjini]

After almost 30 hours of searching a good instructor for clean arch. I found all in one, keep it up

[ahmadaqrabawi]

One of the greatest videos I've watched.
Clean, Direct to the point and not boring

[hassaanqureshi]

There's precisely one channel for which I have the notifications on. And it's this one. Nowhere else have I found such an eloquent dive into DDD with CA.

[WasifKizilbash]

The best, concise, to-the-point, relevant and CLEAR communication!! above all, I really like the way you kept on showing the Diagram and linked it with the Code, that is where we are! I've never seen any .NET video instructors making such a clear and crisp connection to the Infographic vs Code!! great stuff! will definitely cover your entire course!! This is coming from a full stack .NET developer who has been dirtying hands for the last 15 years!! bravo! more power to you mate! love from Australia!

[timschmidt]

I love this so much! I started w episode 13, then immediately jumped back to the start of the series. I'm also a 25+ yr. dev and this is hands down one of the best presentations I've ever seen! Take my subscribe and likes!

[GameSpreePH]

At last! No nonesense presentation. This is the best😉

[therayyanansari]

Right at the end of the video, when you said "this is my first video" that really blew my mind. This video is really polished and complete. Thank you bro. Subscribed as soon as I completed the video. Will be completing the whole series.

[CarlosHerasme]

I was researching a lot about DDD and Clean Architecture. I must say this is the best course I've ever watched.

I'm eager to finish the whole course, I already watched a little bit of the further videos and I definitely loved what I saw.

You rock!

[waliullah]

Just to say brilliant is not enough. very high-level knowledge and resources you have shared in public. A person like me very much benefitted from your channel. Please keep sharing.

[ycarobatalha]

Thank you for this tutorial. I'm a junior developer and I'm using this video to study DDD in english. Sometimes, you speak fast but I can back the video and listen again.

Success in your channel.

9:38 In Clean Architecture the Presentation Layer's dependency on the Infrastructure Layer is a runtime dependency, not a direct reference between the projects. In this case CA would use the Dependency Inversion Principle to invert the dependency between the two layers by making them both depend on an abstraction (an interface). This abstraction is defined in the Application (or Core Domain) layer. So instead of Presentation Layer => Infrastructure Layer, you do Presentation Layer => Abstraction <= Infrastructure Layer. At runtime, the DI container is responsible for injecting the correct instance of the Infrastructure Layer dependency, based on the registered dependencies. For example, if BubberDiner.Api needs a repository from the Infrastructure, it should reference it as IRepository<Type>, an interface it gets from the App Layer. Infrastructure also depends on IRepository<Type> from the App Layer in order to implement that interface.

[bmassioui]

Thank you for the simplicity and the way how to turn theoretical articles and courses into reel artifact

[carsugarmodels]

Awesome start! Finally finished this first video hands-on. Starting with the next one! Keep doing this same fantastic quality videos! Thanks.

[yannistocreau]

Software architect here, I really like your way to present things. It's clear, concise, and SHORT. You really don't beat around the bush and go straight to the point. So take my like sir !

[NaveenKumar-hdmp]

Loved your way of explanation from scratch....

[wolfgangdiemer]

Seeing the master mind of "throw, error-or, ..." at work, great. Thank you, for your amazing stuff.
