Clean architecture with node.

[vivek poddar]

Hi,

I am have started a clean architecture based node application. I need some advice or example to get running in the right direction.

What I have done so far:

* Start with a basic directory structure.

* Set up the basic requirements.

* Doesn't care about the details like persistence, UI etc.

* Set up some basic acceptance tests.

Hey vivek.  I'm not going to claim this is 100% correct when you talk about applying the clean code architecture but I tried at a previous employer when I was building a new Node.js API.  This isn't code but illustrates how I did approach coding the API.

Clean Architecture Diagram Modified to Relate to my Web Service

It probably needs a little work but hopefully this helps.  I've been told by a friend who thinks this is "overarchitecting" but I do disagree with him on it (at least at this point in time until convinced otherwise). This was an API that was critical to the company and going to be used internally and also called externally.

Note: one correction I need to make on my diagram(s) is that I have an incorrect arrow going from repository to interactor.  It's actually supposed to be pointing down from interactor to repository.  I'll have to update it so that it's more accurate to how I did actually design it and also shows that nothing below is depending on something above which in this case it implies my repositories are talking to my interactors which is just a error on my part in the drawing.

Hi Dave,

I appreciate the detailed design and pictorial representations. I am still finding difficult to find some working code where I can see how they are implemented in nodejs. I don't know if you can share code with me but a working prototype would be great.

Thanks,

Yeah, thank you for the diagram. It's really neat. I too would love to see some code.

I missed the concept of the Usecase in your code, I think that the: getRandomQuote(), could be that (you got 3 untested clauses in there). I'm trying to make a concept of the CA in Node too, but using Promises (not quite straight forward).

Maybe It'll give you some ideas, and be free to give me some feedbacks also. :)

@Dave

Nice work with the PDFs!

Hi @vivek,

if you are still interested in delving into Clean Architecture with Node you can check out this post: 

https://solidgeargroup.com/clean-architecture-in-nodejs

Where some architecture designs are discussed and you have some code examples of Clean Architecture integrating both a REST and a GraphQL APIs, db connection with MongoDB, and unit tests.

So...I'm still working on improving my Clean Architecture approach in the backend (so don't take the way I do it as "ideal", I'm sure I can improve on it) but I'll be streaming hopefully to work more on that here in the near future: https://www.twitch.tv/wedotdd

Hi Juan,

Thanks for sharing the link but it feels somewhat incomplete to me.

The author says that code is testable but I can't see dependency injection anywhere.

I still think there is a need for someone expert to chime in.

Thanks,
