For me this looks just awful.

If you will force us (the community) to use CompA over OptA we will move to React because there will be no more differences. We have created over 50 complex projects in Vue/Nuxt and I need to say that all employees just loved to work on them because of the OptA approach (all my employees have React background).

Maybe I'm a dinosaur with 19 years of experience, but I have to say it - I returned to programming after many years after a burnout because programming in Vue with OptA is pure pleasure.

Please don't change that.

@rafal-ksiazek-rmtcfm-com I strongly disagree with you. Have you created a large-scale app with Vue options API? Code organization and reuse becomes a real nightmare. In contrast, with the new composition API, the code is much cleaner, better organized, more readable, and more maintainable. The Composition API is a pleasure to work with if you value things like clean code and best coding practices.

@martinszeltins Yes, we have. Few of our apps are the #1 in some countries. I understand that CompA has advantages over OptA and the whole process of development of VueJS framework is much better (much easier to write unit tests). From architectural point of view you are right.

But please don't remove the OptA and don't force us to use CompA. We are using it in rare cases. The reason we move from React to Vue was the simplicity and understandability of the code.

And the code I see on the top of this page is again awful. For me, it's like stepping back in time 15 years.

@rafal-ksiazek-rmtcfm-com The Options API is not being removed, it will stay and co-exist with the Composition API. However, I do not see anything awful about the code you are referring to. The only thing I would improve would be to move each composable into its own file / module. What don't you like about this code? It nicely follows the SOLID principles for clean code, which is the right direction.
