Hi, my current Phoenix project involves a website with a lot of different functionality, like a digital store, chat system, file uploads, blog posts, comments, etc. How can I go about developing this project so that each feature is a self-contained unit that I can reuse in future projects? For examp…

AFAIK there is no support for this out of the box but it should be doable. Assuming you really want to have multiple Phoenix apps, then going down the umbrella app route is most likely the best approach. For that you would have one “main” app, and a number of “sub” apps (just by name though, from…

Thank you very much for your detailed answer @wolf4earth ! It is a good starting point for me and I will definitely attempt it. Do you think it will be ok to make associations between models as needed, even though they live in different umbrella apps? For example, the “main” app will have a user mod…

[image] magosi: Also, why is this not a frequently asked question? Do other people just write their apps from scratch? I have re-used modules many times from different Phoenix projects: they are very portable. The only wiring that was needed to install them was to reference them somewhere (e…

I don’t think it a good idea, given your requirements that apps are self-contained. What you are proposing definitely breaks it. What you need is sort of micro-service design. There is an accounts application. It is concerned with users and everything related. It also publishes changes (PubSub, AMQ…

Thanks @egze . So if I understand correctly, its best to implement microservices revolving around core datastructures that can subscribe to one another, but only in the case where you write a suite of apps that will use these services. Otherwise for individual apps, write it from scratch?

Yeah, I would not bother with such strict boundaries for a simple application. Btw, have a look at this video: https://www.youtube.com/watch?v=hgDCg3QdZgU
