By injecting dependencies to function args, aren't we loosing out on intellisense? Is there a better way to inject dependencies ?

@DevMastery

+Kashif Minhaj Editors like VS Code do a decent job of guessing after a while, but intellisense still suffers a bit for sure. One option is to use Flow or Typescript along with an Editor that supports it so that you can specify the type of each parameter on the way in. No guessing.

If we use something like mongoose, should we make entities become mongoose schema? Or we should pass a entity to a function which creates and returns mongoose schema?

@@blackdiz2603 thanks for asking such a great question. Mongoose belongs to the outermost circle, so it would occupy the same role as our MongoDB Driver. Meaning, we would inject a Mongoose model into our CommentsDB module and use it exclusively to interact with the database. It's very important not to confuse a Mongoose model with a business Entity. We need to make sure that business rules are as independent as possible from third-party frameworks like Mongoose. A mistake I see too often in legacy code bases is that they built their Business Objects on top of - or even inside of - some third-party framework and then after a few years their codebase becomes an unstable mess because the underlying dependencies have been deprecated but no one wants to touch them because it would risk breaking all the (often poorly or not at all documented) business logic of their app. Clean Architecture was designed specifically to avoid this situation.

Do you think the upcoming class features (public/privates, getters, setters) will change this implementation at all? in the comment entity: export default (dependencies = {}) => class Comment { constructor(data = {}) { // code to validate and store the comment data in 'this' goes here } #author; #text; #replyToId; } in a use case: // instead of const comment = makeComment(info) const comment = new Comment(info) Also as a side note, it's really hard to find examples of people working with the clean architecture, in nodeJS, using more than just one entity. It would be super helpful if, for example, you changed the comment author to an Author entity and showed how you establish and validate things like many to one relationships at the business-logic entity level.

The inject is not the important part; the adapters and interfaces are the important part. He said the outer layers should depend on the inner layers, which means the external tools and frameworks should depend on our adapters and interfaces. The make-callback.js at the end of the video is a perfect example. Also, imported/required modules can still be mocked in tests. Injection with the wrapper function is not necessary and even adds bloat.

I think it is part of SOLID principals, in the D part, dependency inversion principals. where the high level module should not depend on low level module, those two must depend on abstraction. high level module is the code that we write ourself, and low level code is the dependency such as mongoose, node-postgres, mysql that 'abstracted' as db connector

Yes agreed, so much content that talks about clean architecture, but this actually shows it in action! And only now I’m starting to understand what it’s all about.

Best video on Clean Architecture I have come across till now. Thankyou so much!

Mind = Blown. For someone who thought who knows enough about structuring code and model data and apis, this is an eye opener. This is proper pro content, at times I was falling behind because there was so much things to pick up. Please keep making videos. Thanks

This video is a great example of what a video tutorial should be related to devs. Source code and diagrams. Business explanations, and concrete implementation. Absolutely the greatest

Incredible! Best explanation of the Clean Architecture I've ever seen.

Absolutely gorgeous! What clear and concise explanation! Please, please keep making DDD videos like this one. I've subscribed to your content.

Please, don't stop making videos. You're a really good teacher

Great explanation! Not much channels out there focus on the architecture side of software development. More of these, please and thank you!

First time a Node.js setup feels REALLY RIGHT! I love this. Especially the "mini-main" index.js files that do all the dependency injections for a small module. Great work!

probably the best video on Onion/Clean arch I've watched so far. Concrete examples helped so much. We have been trying to adhere to onion at work to make our lives easier down the road and I was second guessing myself sometimes. Thanks for clearing up the fog

I had to watch probably too many times, but thank you. This is the best programming video I have ever watched.

These are the kind of tutorials I have been looking for years and here I have got one. Keep making these kind of videos.

Both of your technical and teaching skills are remarkable. The best illustration of Clean architecture I've could find so far. Thanks sharing!

This is a wonderful explanation, I haven't seen this type of clarity with concrete examples for clean architecture with node.js anywhere else. Nice work!

Love what you did with the video man, and also a very clever way to implement the adapter pattern for the sanitize library, the only thing that I would change, is that I prefer to have individual files for all the dependencies with their adapters, instead of having just one big file with all the third party and factory functions. But this video is a must see! thank you

One of the best video I've seen so far, finaly understood what dependency injection was used for. Hard to understand when you didn't studied IT and you convert to fullstack dev by yourself, now it's finally clearer. Thanks a lot. Subscribed of course.

@Dev Mastery Fantastic balance of principles, application, and code details. Are you still making vids? (Or are you planning to start up again?) I would love a follow-up video that goes into some more deep-dive aspects of this practice. Perhaps also a video of common “gotchas” for people trying out this architecture for the first time.

Thanks a million for this video!! I've read the Clean Architecture by Robert Martin, but could not understand how to apply the provided circular diagram in practice. Frankly speaking, I understand only 20-30% of what is going on in the video because of the lack of knowledge and experience, but it fires an awesome feeling of curiosity and desire to continue enhance my skills to become more and more professional as time goes by. UPD: I'm having so much emotions and insights watching this video so that I will download this video and keep it on my external drive for future reviews!! (if this video will accidentally disappear from KZread)🙂

This should be the best Node video in the whole internet !

Liked and subscribed. This architecture is the real meaning of plug and play. I love how each and every thing can be tweaked without affecting others. Loved it.

This is a really way to code in node, the use case break down into services is really intuitive

Thank you so much, it all makes so much more sense now. Clean Architecture is a difficult concept to grasp through, just because it has tricky parts such as "No inner circle depends on outer circle" and you're like: "Well, then how the hell am I going to insert a new object into the database if I cant depend on it? You explained it very well, thank you for that.

Amazing video! More insightful content in this 33 mins than tons of other typing tutorials out there. Thank you very much!

Great Video! Always wanted to understand how to implement dependency injection on a practical use case.

Thank you for creating these videos. Your insights are incredibly helpful and I hope you'll continue to expand on this topic in future videos. Coming from .Net Core and Entity Framework, I must say building REST APIs in Express looks like the wild west, in that everyone has their own structure and way of doing things. Whereas, implementing clean architecture in .Net with the Repository and Unit of Work patterns seems more straight forward. In the .Net world, two WebAPI projects built by different developers at least share some resemblance. Having gone through many tutorials, I can't really say the same for Express. But I guess that's the nature of unopinionated JavaScript frameworks. So, I'm now trying to find some kind of scalable structure to use in my Express projects. So far yours is the most logical I've seen, but it seems like TypeScript would simplify things quite a bit here. I'm interested in your thoughts on this.

​@Ellie Maynard I agree. Virtually everyone has their own concept of how an Express or React project should be structured. There are very few standards in JavaScript compared to other languages. The approach shown in this video is an attempt to carry over architectural concepts that are more commonly found in C#/.Net and Java. I'm not saying it's bad, but you're correct that it's far from being a standard in the JavaScript community. While I applaud the idea, I really don't see this catching on anytime soon. Many JavaScript developers argue that moving in this direction is going back to the old OOP model they didn't like in languages like C# and Java because of all the boilerplate code necessary to get up and running. Plus, IMHO, to do this properly you'd really want to use TypeScript anyway. Not many bloggers or tutorials use a JavaScript "clean architecture" approach. I asked one prominent advocate (who promotes clean architecture along with domain-driven design or DDD) 'Why not go with ASP or Spring Boot in the first place?'. The reason he said was that he'd already built his startup on Express and later ran into maintainability issues as the project grew, so he borrowed enterprise development concepts popular in other languages and refactored his existing code base to accommodate these patterns. Because of his earlier struggles, he was now attempting to spread the word in the JavaScript community about the need for better design. I like what he's doing, but again, I don't see these patterns becoming the norm amongst JavaScript developers. As for me, I originally returned to Node (Express) because I got frustrated with all the boilerplate I was writing in ASP Core to build a basic REST API (albeit with repositories and a layered architecture like the one shown here). Express is great a first. However, it didn't take long before I was fighting to get popular third-party npm packages to play nice together without all kinds of hacks and workarounds. Having worked in software development for around two decades, the conclusion I came to is the Microsoft ecosystem is more mature and standardised. Microsoft's packages work together without a lot of hacking and compromise. So, I think it's worth the extra boilerplate code in the long run to go with ASP Core. (However, I might still choose Node if time and money were a constraint and I expected the structure of the program to change a lot. i.e. Node is better for the uncertainties of a startup but less suited to enterprise applications.) I continue to use React for my front-end, but I've switched to TypeScript. I still wish there was more consensus on how to structure a React application and how and when to sync state with the back end, rather than being left to fumble around and see what works. Again, unopinionated frameworks create a wild-west situation where everyone can argue their way is the correct way. Hence the reason why, as you said, no one's code seems to make sense until it's explained. People love to criticise PHP, but I suspect there are as many anti-patterns floating around in JavaScript projects these days as anything written in PHP. And while there are better, more organised Node frameworks than Express, Express is by far the most common Node framework you'll run into in tutorials or in the workplace.
