A light Universal modal Component for Vue 3

vue-universal-modal

A light Universal modal Component for Vue 3.

Introduction

vue-universal-modal plugin is based on the teleport.
It is very light and simple, but it provides essential features for modal use in applications.
(Such as Add & Remove, Visible & Hidden, Transition, Auto bind keyboard and mouse to close, Support SSR, A11Y...)
Here is the Demo

Features

• Based on the teleport
• Provides essential features for modal
• A11Y
• Support SSR (Insert rendering source into SSR context, Mount from Client-side)

Install plugin

npm install vue-universal-modal

Insert teleport element in your html

...
  <div id="app"></div>
  <!-- teleport target -->
  <div id="modals"></div>
...

Because SSR cannot be implemented by dynamically creating and ref referencing teleport elements, teleport targets must be inserted into html first.

And install plugin in vue application

import 'vue-universal-modal/dist/index.css'

import VueUniversalModal from 'vue-universal-modal'

app.use(VueUniversalModal, {
  teleportTarget: '#modals'
})

Options

app.use(VueUniversalModal, {
  teleportTarget: '#my-modals',
  modalComponent: 'MyModal',
})

name	type	detault	description
teleportTarget (required)	string		Teleport target
modalComponent	string	'Modal'	Global modal component name

Usage modal

Insert the component wrapped with the modal component. (Slot based)

<template>
  <p>
    <button @click="showModal">
      Show modal
    </button>
  </p>
  <!-- If the option changed modal component the name
  <MyModal>
  -->
  <Modal
    v-model="isShow"
    :close="closeModal"
  >
    <div class="modal">
      <p>
        Hello
      </p>
      <button @click="closeModal">
        close
      </button>
    </div>
  </Modal>
</template>

<script lang="ts">
import { defineComponent, ref } from 'vue'

export default defineComponent({
  setup () {
    const isShow = ref(false)

    function showModal () {
      isShow.value = true
    }

    function closeModal () {
      isShow.value = false
    }

    return {
      isShow,
      showModal,
      closeModal
    }
  }
})
</script>

<style scoped lang="scss">
.modal {
  width: 300px;
  padding: 30px;
  box-sizing: border-box;
  background-color: #fff;
  font-size: 20px;
  text-align: center;
}
</style>

v1.0.x -> v1.1.x change point

• Use v-model instead of v-if for modal component insertion
• If you control the insertion of components with v-if, the close animation will not work.
• emitClose slot argument was deprecated.

  }
})
</script>

Handle global CSS

You can change it directly to your own style by referring to the source

.vue-universal-modal {
  /* Change dimmed color */
  background-color: rgba(255, 255, 0, 0.3);
}
.vue-universal-modal-content {
  /* Align to top (flex-direction property value is set to column) */
  justify-content: flex-start;
}
