@vuejs

@formkit

Sustainable open source is hard 😔. After shipping freely available Open Source for almost 3 years, we launched some *optional* paid add-ons and got these kind of takes right away.

Apparently my tweet made Vue Reddit melt 👀.
So here’s my reasoning for why I think dropping the Options API from Vue core would be beneficial:
3 main reasons:
1. Multiple ways of doing the same thing fractures community projects and makes it increasingly hard for the
Vue 4.0 proposal: no feature additions but it makes the options API disabled and marked deprecated. Can still be enabled via a shame flag moving forward.
Standardization for the win.

This is one of the most attractive things about Vue to me. It is the most open and least “corporate” of the options - fueled mostly by passion and great engineers doing what they love.
That’s also why we see so much “framework agnostic” work coming from the Vue community.

I hear this argument a lot — but if the dev’s you hire are only capable of writing React (or Vue/Svelte for that matter) then you have talent evaluation problems not framework problems.
@CodingGarden
I'd try Vue for a side project.
But for a business, using Vue instead of React means cutting the talent pool of potential hires in half.
Finding great talent is already hard. Companies can't afford to shoot themselves in the foot by choosing a less-widely-used tech stack.

#VueJS
devs — did you know an object literal defined in a <template> block *creates* a new object on each render? This means your watchers will also fire on every render. Simply moving the definition to the <script> tag can be a significant performance boost.

for years now while they kept CRA on the docs.
If they didn’t make *any* recommendations that would be one thing, but to recommend things like Gatsby, and not even mention Vite is…politics.
“Vite isn’t a framework” isn’t a solid defense either…

The Svelte 5 changes are unquestionably the right decision for the project.
1. Compiler reactivity has halting problem limitations that evaporate with signals.
2. Unlocking composability will lead to community innovation.
Is it a lot more like Vue? Yes! But who cares?
Lots of folks have noticed superficial similarities between Svelte's runes and Vue. There definitely are some ways in which we're moving closer to other frameworks — not a bad thing! But in other ways our designs remain quite different

From Svelte’s perspective the grass was greener for sure, but it does kinda take away Svelte’s biggest USP imo (brevity).
It’s definitely svelte stepping into that middle ground — a little less compiler and a little more runtime, a space held almost exclusively by Vue.
