Re: [IBMiOSS] Node code organization -- OPENSOURCE

Bear in mind that this whole thread is about node.js - not every possible web framework out there. It’s amusing that a proponent of MVC would likely be a greybeard :)

I think that many shops are still striving to get to a MVC model and see it is the holy grail, but the point is that node.js is a relatively new technology (for some at least) and that learning it or migrating to it does not mean you have to implement a MVC pattern. There are other things to consider that may be better (for your environment).

Well said Pete. Sometimes change for changes sake, and because it was done that way before you therefore it's not right anymore is a problem.

The goal is easy, understandable, maintainable code by the developer that comes after you. MVC is easy, straight forward, and maintainable. Passé, maybe but who cares. Sometimes we greybeards aren't just old, rather we are experienced.

So, everyone will have a opinion on this...take mine with a grain of salt....

The MVC pattern was driven by the need to move from a monolithic program to a structure that was more modular, maintainable and organized. So, even a monolithic pre-MVC pattern program would have subroutines that broke out the different programmatic components. So, building reusable modules of Models, Views and Controllers, even if they weren't completely reused as a components, was just a logical extension of a need for organization wrapped around the available technology.

The latest craze of "micro-services" is just an extreme extension of MVC into today's heterogeneous technology environment. The pendulum will swing back into more complete "packages" rather than micro-services at some point. There is just a practical balance of functional separation and maintainability that will rule the day.

The term MVC may be passe, but the concept is alive and well and now living in a micro-service world....

Do you really want a traditional MVC pattern? That’s generally considered a bit passé. If you are developing something new then I would go with the component approach (ala React, Angular 2 and beyond, Vue etc).

I ran this command:

$ express hello_world

It generated these directories:

-bin

-public

---images

---javascripts

---stylesheets

-routes

-views

With MVC, I think V=views and C=routes, and I'd need to create a dir for M. Does that sound about right?

Some frameworks are opinionated and some aren't so it depends if you
are going to end up fighting conventions or not. I think just about
any framework with an MVC design pattern will group like code/objects
together and I even do that for my RPG stuff (which has no opinion).
Node itself I don't think cares about structure. It is what ever is
familiar to you, but in most cases my guess is that you'll follow
either a logical grouping of like code:

/Model

/View

/Controller

Or use a naming convention: model1.js, view1.js, controller1.js
under a single folder. My Java and Rails projects follow the
convention above; A structured, opinionated layout. My Node projects
follow the latter unless they use a framework that has it's own opinionated structure.

I'd say with complex apps, MVC by folder groupings may be easier.
For small apps I'd keep it simple....
