Next.js for example, comes packed with anything and everything one might need to build an app. Sitting on the promise of hyperproductivity with "simplicity". Plus, is made of single responsability principles set of modules, kind of necessary to build a solve-all needs framework.
And it does that.
A bit like Angular, set to solve everything front-side. With modules not entirely tightly coupled but sort of to get the full solution.
And it did that.
Then we have outliers like React, which stayed away from trying to solve too many things. But the developers have spoken, and soon enough it became packed in with other frameworks. Gatsby etc. And community "plug-ins" to do that thing that dev think should be part of the framework.
And they did that, solved most problems from authentication to animation, free and open source sir, so that developers can write 12 lines of code and ship 3 features per day in some non innovative way, but it works, deployed in the next 36 seconds, making the manager happy as he was wondering how to justify over 100k in compensation going to a young adult who dressed cool and seemed to type fast.
Oh no! dependency hell. I have to keep things maintained, I have to actually upgrade now, LTS expired, security audits on my back, got to even change my code that worked perfectly well and deal with "errors", I can't ship 3 features by the end of today.
We need a new framework!
