Introduction

Vue3Mount is a lightweight api for dynamically mounting Vue components.

Features

• Supports reactive props
• Supports inject/provide api
• Provides Custom directive for handling transition
• Supports Options API

Getting started

1. Using NPM

Install

npm install vue3-mount
// or
pnpm add vue3-mount

Register

// app.ts
import Vue3Mount from 'vue3-mount'

const app = createApp(App)
app.use(Vue3Mount)

2. CDN

Install

<script src="https://unpkg.com/vue3-mount"></script>

Register

const {Mount: Vue3Mount} = window.Vue3Mount
const app = createApp(App)
app.use(Vue3Mount)

Usage

Define a Portal

// App.vue
<template>
  <!-- Rest of the code -->
  <Portal/>
  <!-- Define a named mount target -->
  <Portal name="modals"/>
</template>
<script lang="ts" setup>
import {Portal} from "vue3-mount"
</script>

At-least one portal is required.

Mounting the component

// SomeComponent.vue
<template>
  <button @click="mountModal">Mount Modal</button>
</template>
<script lang="ts" setup>
import {h}        from "vue"
import {useMount} from "vue3-mount"
import Modal      from "./components/Modal.vue"

const mount = useMount()

function mountModal() {
  const node = mount(() => h(Modal, {
    // props
  }))

  // or mount to a named mount target
  const node = mount(() => h(Modal, {
    // props
  }), 'modals')

  // unmount the component
  node.unmount()
  // or destroy the component
  node.remove()
}

</script>

Using the vMount directive

// Modal.vue
<transition name="fade" appear>
    <div v-mount>
      <!-- Rest of the code -->
    </div>
</transition>
<script lang="ts" setup>
import {vMount} from "vue3-mount"
</script>

vMount is a wrapper around native vShow directive, but it also handles transitions for custom mounted components.

Unmount the component

// Modal.vue
<script lang="ts" setup>
import {getNode} from "vue3-mount"

const unmount = getNode()
// const unmount = getNode(()=> /** beforeUnmountHook */)

// unmount the component
// vMount directive will handle the transition
unmount()
// or if you want to destroy the component instantly
unmount.force()

</script>

Using Options API

Mounting the component

// SomeComponent.vue
<template>
  <button @click="mountModal">Mount Modal</button>
</template>
<script lang="ts">
import {defineComponent, h} from "vue"
import Modal                from "./components/Modal.vue"

export default defineComponent({
  methods: {
    mountModal() {
      const node = this.$vueMount(() => h(Modal, {
        // props
      }))

      // or mount to a named mount target
      const node = this.$vueMount(() => h(Modal, {
        // props
      }), 'modals')

      // unmount the component
      node.unmount()
      // or destroy the component
      node.remove()
    }
  }
})

</script>

Accessing Node instance from Mounted component

// Modal.vue
<script lang="ts">
import {defineComponent} from "vue"
import {NodeMixin}       from "vue3-mount"

export default defineComponent({
  mixins: [NodeMixin],
  methods: {
    unmount() {
      this.$node.unmount()
    },
    destroy() {
      this.$node.remove()
    }
  }
})
</script>

Todo

• Add unit tests
