vue-demi VS rfcs

You can use the composition API in Vue 2 -- check out vue-demi. I'm using it in a couple vue 2 projects, and it's quite solid.

Supports both Vue 2.x and Vue 3.x all thanks to vue-demi

I used vue-demi so both Vue 2 and 3 are supported.

It supports Vue 3 and Vue 2 (via composition-api plugin) powered by vue-demi.

It's generally possible if you stick to shared syntax and use something like vue-demi: https://github.com/vueuse/vue-demi

Or another idea is to use vue-demi to slowy rewrite components in Vue 3 and import them with demi in vue 2 (existing platform), repeat this until we have everything rewritten.

It's possible to achieve this by using a developing tool that the same @antfu created called Vue-demi.

We started experimenting with this ling of thought almost 3 years ago:

- First take (ref sugar), Nov 2020: https://github.com/vuejs/rfcs/pull/228

- Take 2, Aug 2021: https://github.com/vuejs/rfcs/pull/368

- Take 3, Nov 2021: https://github.com/vuejs/rfcs/discussions/369

We provided it as an experimental feature and had a decent number of users trying it out in production. The feedback wasn't great and eventually decided to drop it. https://github.com/vuejs/rfcs/discussions/369#discussioncomm...

This is a personal preference, but I use ref almost all the time. Despite tediously writing the .value to access the ref’s value, the Vue team is aware of the problem, and the open RFC - Reactivity Transform, was aiming to solve this issue, however, seems like it was abandoned.

To stay updated, follow the RFC at https://github.com/vuejs/rfcs/discussions/503.

This was a good change. Evan has always been extremely good at putting his finger on the pulse of the frontend community. If there's a feature or paradigm that people love that would fit in Vue, Evan will incorporate it. Over the years, Vue has implemented (and sometimes later deprecated) dependency injection, JSX support, custom elements, Angular-style class components, Svelte-style ref sugar, and now Solid-inspired compiler optimizations. They even changed the order of a Vue file to match that of Svelte: first the script, then the template.

Now the $on has been removed, but the event subject is causing some confusion, see: https://github.com/vuejs/rfcs/discussions/397

The RFC has shown that this feature is very controversial, with lots of implications. Personally, I liked it at first, but now I'm against it.

Here is the Current language: https://github.com/vuejs/rfcs/blob/function-apis/active-rfcs/0000-function-api.md

Plus, even that there is a real possibility that the controversial Reactivity Transform RFC leads to a Vue 4 version, it is likely to bring just minor breaking changes from Vue 3.
