> I think the irony here is that MVC in its original form has largely fallen out of fashion the last few years.
Not really — unless React is the only library you use.. MVC is still the best pattern. If you are an iOS developer you may already be familiar with MVC in Cocoa. Most UI frameworks, including ASP.NET Core, JSP and JSF (Java based frameworks), Ruby on Rails, and Django (Python) are all based on MVC. That's no accident. These disparate platforms — mobile and Web — all converged on MVC because it is the best architectural pattern for developing user interfaces.
There’s a whole ecosystem of alternatives that have sprung up I have a feeling you haven’t tried (not MVVM or anything like that). Without appealing to any of them you aren’t convincing.
Even within the frontend world and not in React you have all sorts of new state systems and structures that are in my opinion far more intuitive, less code, less cross cutting concerns, easier to change and grow more naturally. The gist of it is either a global state store with cursors and namespaces (I like this less than most) or a global state system with state split out (see Recoil) or an entirely tree based reactive state system (see mobx-state-tree or mobx-store) or even just nesting reducers or any simple nesting state container (pure react, zustand). I’ve recently put together gqless[0] with a state system similar to recoil but simpler (sort of like use-atom). It’s wonderful.
Your data is a tree/graph, you app is a tree, your file system is a tree, everything matches. You just slot in state with corresponding actions and at the level of the view hierarchy where it first becomes relevant (router at top, view controllers are spread in the middle layers however needed, and leafs get their own state as needed). And all data level things stay up in the graph, which I guess you could argue is an M sitting above it all, the VC are blurred together with more C at the top of the tree and pure V at the leafs. Even styling is all encapsulated where it’s used. Each piece is a lego block that can be moved around. And yes, it works, and works well, even without all the handlebars of Rails.
Wouldn’t dream of going back. It’s perhaps not a mature enough ecosystem for most to navigate their way to getting a good DX on a stack like that. Many pieces have rough edges if you don’t know what to avoid, it’s not like these huge mature frameworks that keep you away from scary stuff but also box you into a rigid structure. But of course it means you can do all sorts of things unimaginable in MVC land.
Most of the frameworks you mention above are 5+ years old. Back when jQuery was the THE THING to know.
In any case, my critique is not levied against MVC the pattern, rather, how it is manifest. One can logically follow MVC without the physical separation of concerns (files). It's a continuum: You start by defining your state, view, and orchestration all in the same place. Should any one piece of the above suddenly need to be reused elsewhere, you then abstract as necessary.
I was pushing back against the idea that "inlining" CSS/JS with HTML is poor practice. What React achieves, because it demands you inline JS (and CSS if you want) with the HTML, is a simple, declarative development paradigm. It's like reading a function. No procedural ad-hoc `let el = document.querySelector('#id')` garbage getting in the way. The behavior is with the component, not around the component. In many ways, this is how OOP was supposed to work.
