Interop Vue 2 components with Vue 3 apps and vice versa!

    I'm a Vue 3 app... but I can use Vue 2 components!
    <some-vue2-component />
import SomeVue2Component from 'some-vue2-component'
import toVue3 from 'vue-2-3/to-vue-3'
export default {
    components: {
        SomeVue2Component: toVue3(SomeVue2Component)

🙋‍♂️ Why?

  • ⛵️ Smooth Vue 3 migration strategy Incrementally rewrite your components to be Vue 3 compatible!
  • 🔥 Expand Vue 2 and 3 ecosystem Tap into the vast Vue 2 ecosystem from your Vue 3 app and vice-versa!

🚀 Install

npm i vue-2-3

🚦 Quick Setup

  1. Import vue-2-3/to-vue-2 or vue-2-3/to-vue-3.

    • Use toVue2 to interop Vue 3 components with a Vue 2 app

      import toVue2 from 'vue-2-3/to-vue-2';
    • Use toVue3 to interop Vue 2 components with a Vue 3 app

      import toVue3 from 'vue-2-3/to-vue-3';
  2. It will automatically try to resolve Vue 2 & 3 via bare specifiers vue and vue3 but if it can't find them, you can manually register them. You only need to do this once so it's suggested to be done at the top of your app.

    import Vue2 from 'vue2';
    import * as Vue3 from 'vue@next';
    toVue2.register(Vue2, Vue3);

    For Vue 3, you can provide the necessary exports createApp and h to keep dependencies to a minimum:

    import { createApp, h } from 'vue@next';
    toVue2.register({ createApp, h });
  3. Pass the component in and start using it!

    import SomeVue2Component from './some-vue2-component';
    export default {
        components: {
            SomeVue2Component: toVue3(SomeVue2Component)
