Package Exports

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@j1nn0/vue-modal-dialog) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

⚙️ Peer Dependencies

Before using this component, make sure you have installed the following peer dependencies:

npm install vue @vueuse/core @vueuse/integrations focus-trap

yarn add vue @vueuse/core @vueuse/integrations focus-trap

These dependencies are required for the library to function properly.

🛠 Usage

You can use this component in two ways:

Import individually (recommended, enables tree-shaking)
Register globally as a Vue plugin

1️⃣ Individual Import (recommended)

<script setup>
import { ref } from 'vue';
import { VueModalDialog } from '@j1nn0/vue-modal-dialog';
import '@j1nn0/vue-modal-dialog/dist/vue-modal-dialog.css';

const isOpen = ref(false);

const submitForm = () => {
  alert('Form submitted!');
  isOpen.value = false;
};
</script>

<template>
  <button @click="isOpen = true">Open Dialog</button>

  <VueModalDialog v-model="isOpen">
    <!-- Header slot -->
    <template #header> Dialog Title </template>

    <!-- Body slot (default) -->
    <p>
      This is the body content of the dialog. It supports long text and will wrap automatically.
    </p>

    <!-- Footer slot (optional) -->
    <template #footer>
      <button @click="isOpen = false">Cancel</button>
      <button @click="submitForm">Submit</button>
    </template>
  </VueModalDialog>
</template>

2️⃣ Global Plugin Registration

// main.js
import { createApp } from 'vue';
import App from './App.vue';

import { VueModalDialogPlugin } from '@j1nn0/vue-modal-dialog';
import '@j1nn0/vue-modal-dialog/dist/vue-modal-dialog.css';

const app = createApp(App);

// Registers globally as <VueModalDialog> by default
app.use(VueModalDialogPlugin);
// Or specify a custom name
// app.use(VueModalDialogPlugin, { name: 'CustomName' });

app.mount('#app');

Use <VueModalDialog> (or your custom name) anywhere in your app without importing it:

<template>
  <VueModalDialog v-model="isOpen">
    <template #header> Global Dialog </template>
    <p>Body content</p>
  </VueModalDialog>
</template>

🌐 CDN Usage

You can use @j1nn0/vue-modal-dialog via CDN without any bundler. Both individual import and global plugin usage are supported.

📝 Notes on Multiple Modals

This library is designed with the assumption that only one modal is open at a time.
Opening multiple modals simultaneously may cause the following issues:

Backdrops stacking, making the screen too dark
Focus trap not functioning correctly
Escape key behavior becoming ambiguous
Accessibility attributes (e.g. aria-hidden) breaking

Therefore, it is recommended to control modals on the application side so that only one is visible at any given time.

At present, supporting multiple simultaneous modals is not planned.
If there is strong demand, it may be considered in the future.
