composition-api VS vueuse

Composition API (now built-in): Composition API is a built-in feature of Vue 3 and is currently available to Vue 2 through the officially maintained @vue/composition-api plugin. In Vue 3, it's mainly used together with the syntax in single-report additives. Here is a basic instance of a issue using Composition API:

√ What would you like to build? » App with Quasar CLI, let's go! √ Project folder: ... quasar-qrcode-scanner √ Pick Quasar version: » Quasar v1 (Vue 2) √ Pick script type: » Typescript √ Package name: ... quasar-qrcode-scanner √ Project product name: (must start with letter if building mobile apps) ... Quasar QR Code Scanner √ Project description: ... A Quasar Project √ Author: ... √ Pick a Vue component style: » Composition API (recommended) (https://github.com/vuejs/composition-api) √ Pick your CSS preprocessor: » Sass with SCSS syntax √ Pick a Quasar components & directives import strategy: (can be changed later) » * Auto-import in-use Quasar components & directives - also treeshakes Quasar; minimum bundle size √ Check the features needed for your project: » ESLint √ Pick an ESLint preset: » Prettier

I'd just found out about this back port of the Composition API to Vue 2 (https://github.com/vuejs/composition-api). What's your experience with that? Is it stable enough to use in a production project with +1000 users? Or is more experimental?

While Vue 3 has had a paradigma change by switching to the Composition API as the primary API, you still can use the "old" Options API which stays mostly unchanged to Vue 2. And vice-versa Vue 2 actually supports most of the Composition API when you include an additional plugin: https://github.com/vuejs/composition-api

Is it even worth it to use https://github.com/vuejs/composition-api or should i migrate to vue 3. I'm only using vue 2 so i can use the vuetify calendar component.

Npm package: @vue/composition-api

If you can’t migrate to Vue 3 today, then you can still use the Composition API already. You can do this by installing the official Composition API Vue 2 Plugin.

I see that the @vue/composition-api also admits to having some performance overhead when used with Vue 2. And it appears to have quite a list of its own gotchas, judging from the README.

For what it's worth most of Vue 3's features can be backported to Vue 2 apps by including the @vue/composition-api package. I agree with the other comment, the v2 docs will get you very far.

My opinion: Vue, specifically the Vue 3 Composition API. Most of your app state should come from computed() values. Bookmark https://vueuse.org and come back to it often. Go through VueUse's source (the docs for each function link to their source): you'll be surprised at how simple most of it is, and it stands as documentation of best practices for using the composition API in general.

Now, let’s talk about Vue! Once again, we’ll use an external library to handle dark mode simply and quickly. In this case, the library is called VueUse, and you can install it using the command npm i @vueuse/core --save.

Great library. Could use some improvements as said by other (tree shaking, add jsdocs, etc…). Just a quick reminder for the vuejs devs out there we have https://vueuse.org/

Yeah, I figured useHooks was created without knowing about VueUse, but thought they might have become aware of it sense then. It makes sense, because though the code is heading in the direction of VueUse in terms of being maintained and well rounded, the structure of useHooks is quite a bit different. It has the code alongside the Markdown: https://github.com/vueuse/vueuse/tree/main/packages/integrat...

Demo: https://github.com/vueuse/vueuse/blob/main/packages/core/useWebNotification/demo.vue

Also take a look at https://vueuse.org/ which might save you some lines :)

For what it's worth my timeframe is very similar to yours! Started in 2019, no React / Angular. I think looking at great codebases like [VueUse](https://github.com/vueuse/vueuse) shows off the best of composition API.
