Implementing Syncfusion Vue 3 Notifications

Toast

The Syncfusion Vue 3 Toast component displays brief, non-intrusive notifications that auto-dismiss after a configurable timeout. Toasts support rich content through templates, action buttons, animated entry/exit, precise positioning, and programmatic control via ToastUtility.

🛑 Agentic use: Do not execute multiple steps autonomously. Confirm with the user before each action (install, run, file creation).

Quick Start Example

🛑 STOP — Do not start the dev server autonomously. Ask the user to run: npm run dev after setup.

<template>
  <div>
    <button @click="showToast">Show Toast</button>
    <ToastComponent
      ref="toastRef"
      title="Success!"
      content="Your changes have been saved."
      cssClass="e-toast-success"
      :position="position"
      :timeOut="4000"
      :showProgressBar="true"
      :showCloseButton="true"
    />
  </div>
</template>

<script setup>
import { ref, reactive } from 'vue';
import { ToastComponent } from '@syncfusion/ej2-vue-notifications';
import '@syncfusion/ej2-base/styles/tailwind3.css';
import '@syncfusion/ej2-vue-notifications/styles/tailwind3.css';

const toastRef = ref(null);
const position = reactive({ X: 'Right', Y: 'Bottom' });

const showToast = () => {
  toastRef.value?.show();
};
</script>

Quick Utility Toast (No Component Needed)

import { ToastUtility } from '@syncfusion/ej2-vue-notifications';

// Show a success toast instantly
ToastUtility.show('File saved successfully', 'Success', 3000);

// Show an error toast
ToastUtility.show('Connection failed', 'Error', 5000);

ToastUtility works in any Vue composable, store action, or .ts module — no component ref or template needed. This replaces the React pattern of importing ToastUtility from the React package.

Common Patterns

Semantic type toasts

Use cssClass with e-toast-success, e-toast-info, e-toast-warning, e-toast-danger for visual differentiation — see references/toast-templates-and-styling.md.

Static/persistent toasts

Set :timeOut="0" with :showCloseButton="true" for notifications users must explicitly dismiss — see references/toast-timeout-and-dismissal.md.

Action-required toasts

Use the buttons property to add Ignore/Confirm/Undo buttons — see references/toast-configuration.md.

Prevent duplicates

Use the beforeOpen event to cancel duplicate toasts already on screen — see references/toast-services.md.

Limit max visible toasts

Cap simultaneous toasts at N using beforeOpen and element.childElementCount — see references/toast-services.md.

Message

The Syncfusion Vue 3 MessageComponent displays contextual messages with visual severity indicators—icons and colors—to communicate importance and context to end users. It supports five severity levels, three visual variants, close-icon dismissal, custom templates via Vue slots, and full accessibility compliance.

🛑 Agentic use: Do not execute multiple steps autonomously. Confirm with the user before each action (install, run, file creation).

Quick Start

🛑 STOP — Do not start the dev server autonomously. Ask the user to run: npm run dev after setup.

npm install @syncfusion/ej2-vue-notifications
npm audit

// src/main.ts
import '@syncfusion/ej2-base/styles/tailwind3.css';
import '@syncfusion/ej2-vue-notifications/styles/tailwind3.css';

<template>
  <MessageComponent content="Please read the comments carefully" />
</template>

<script setup>
import { MessageComponent } from '@syncfusion/ej2-vue-notifications';
</script>

---

Common Patterns

Severity Messages

<template>
  <MessageComponent content="Editing is restricted" />
  <MessageComponent content="Operation completed" severity="Success" />
  <MessageComponent content="Read these notes" severity="Info" />
  <MessageComponent content="Check your connection" severity="Warning" />
  <MessageComponent content="Submission failed" severity="Error" />
</template>

<script setup>
import { MessageComponent } from '@syncfusion/ej2-vue-notifications';
</script>

Variant + Severity Combo

<template>
  <MessageComponent content="Editing is restricted" variant="Filled" />
  <MessageComponent content="Operation completed" severity="Success" variant="Outlined" />
  <MessageComponent content="Submission failed" severity="Error" variant="Filled" />
</template>

<script setup>
import { MessageComponent } from '@syncfusion/ej2-vue-notifications';
</script>

Dismissible Message

<template>
  <MessageComponent
    v-if="visible"
    content="Your session will expire soon"
    severity="Warning"
    :showCloseIcon="true"
    :visible="visible"
    @closed="visible = false"
  />
</template>

<script setup>
import { ref } from 'vue';
import { MessageComponent } from '@syncfusion/ej2-vue-notifications';

const visible = ref(true);
</script>

In Vue 3, the @closed event replaces React's closed={…} callback prop. The handler updates a local ref and the v-if removes the component from the DOM.

Content Template (Default Slot)

<template>
  <MessageComponent v-if="visible" severity="Success" @closed="visible = false">
    <div>
      <h4>Build succeeded</h4>
      <p>All 42 tests passed.</p>
    </div>
  </MessageComponent>
</template>

<script setup>
import { ref } from 'vue';
import { MessageComponent } from '@syncfusion/ej2-vue-notifications';

const visible = ref(true);
</script>

Skeleton

The Syncfusion Vue 3 SkeletonComponent renders animated placeholder shapes that mimic the layout of loading content. It reduces perceived load time and communicates progress to users with configurable shapes, shimmer animations, and full accessibility support.

Package: @syncfusion/ej2-vue-notifications

🛑 Agentic use: Do not execute multiple steps autonomously. Confirm with the user before each action (install, run, file creation).

Common Patterns

Profile Card Skeleton

<template>
  <div class="profile-skeleton">
    <SkeletonComponent shape="Circle" width="48px" />
    <div class="profile-text">
      <SkeletonComponent width="60%" height="15px" />
      <br />
      <SkeletonComponent width="40%" height="12px" />
    </div>
  </div>
</template>

<script setup>
import { SkeletonComponent } from '@syncfusion/ej2-vue-notifications';
</script>

<style scoped>
.profile-skeleton {
  display: flex;
  align-items: center;
  gap: 12px;
  padding: 16px;
}
.profile-text {
  flex: 1;
}
</style>

Toggle Skeleton on Data Load

<template>
  <div>
    <template v-if="loading">
      <SkeletonComponent width="80%" height="20px" />
    </template>
    <template v-else>
      <p>{{ content }}</p>
    </template>
  </div>
</template>

<script setup>
import { ref, onMounted } from 'vue';
import { SkeletonComponent } from '@syncfusion/ej2-vue-notifications';

const loading = ref(true);
const content = ref('');

onMounted(() => {
  setTimeout(() => {
    content.value = 'Data loaded successfully';
    loading.value = false;
  }, 2000);
});
</script>

Vue 3's onMounted lifecycle hook replaces React's useEffect(..., []). The ref and v-if combo drives the conditional render.

Shimmer List with Pulse Effect

<template>
  <ul class="list-skeleton">
    <li v-for="i in 3" :key="i" class="list-item">
      <SkeletonComponent shape="Circle" width="40px" shimmerEffect="Pulse" />
      <div class="text-block">
        <SkeletonComponent width="70%" height="14px" shimmerEffect="Pulse" />
        <br />
        <SkeletonComponent width="45%" height="12px" shimmerEffect="Pulse" />
      </div>
    </li>
  </ul>
</template>

<script setup>
import { SkeletonComponent } from '@syncfusion/ej2-vue-notifications';
</script>

Spinner

A skill for implementing the Syncfusion Vue 3 Spinner — a load indicator that blocks user interaction with a target element while an operation is in progress.

Quick Start

Minimal Spinner (Composition API)

🛑 STOP — Do not start the dev server autonomously. Ask the user to run: npm run dev after setup.

<template>
  <div ref="containerRef" class="spinner-container" />
</template>

<script setup>
import { ref, onMounted } from 'vue';
import { createSpinner, showSpinner } from '@syncfusion/ej2-vue-popups';
import '@syncfusion/ej2-base/styles/tailwind3.css';
import '@syncfusion/ej2-vue-popups/styles/tailwind3.css';

const containerRef = ref(null);

onMounted(() => {
  createSpinner({
    target: containerRef.value
  });
  showSpinner(containerRef.value);
});
</script>

<style scoped>
.spinner-container { height: 200px; }
</style>

Spinner with Show/Hide Toggle

<template>
  <div>
    <button :disabled="loading" @click="load">Load Data</button>
    <div ref="ref" class="spinner-target" />
  </div>
</template>

<script setup>
import { ref, onMounted } from 'vue';
import { createSpinner, showSpinner, hideSpinner } from '@syncfusion/ej2-vue-popups';

const ref = ref(null);
const loading = ref(false);

onMounted(() => {
  if (ref.value) {
    createSpinner({ target: ref.value, label: 'Loading...' });
  }
});

const load = async () => {
  loading.value = true;
  showSpinner(ref.value);
  try {
    await fetchData();
  } finally {
    hideSpinner(ref.value);
    loading.value = false;
  }
};

async function fetchData() {
  return new Promise(resolve => setTimeout(resolve, 2000));
}
</script>

<style scoped>
.spinner-target { height: 200px; position: relative; }
</style>

Global Spinner Type

// src/main.ts
import { setSpinner } from '@syncfusion/ej2-vue-popups';

// Call BEFORE any createSpinner — sets global default type
setSpinner({ type: 'Bootstrap5' });

Common Patterns

Pattern 1: Async Fetch with Cleanup

const fetchWithSpinner = async (container: HTMLElement) => {
  showSpinner(container);
  try {
    const data = await fetch('/api/data').then(r => r.json());
    return data;
  } finally {
    hideSpinner(container); // Always hide, even on error
  }
};

Pattern 2: Vue State Sync

import { watch } from 'vue';

watch(isLoading, (newValue) => {
  if (!ref.value) return;
  if (newValue) {
    showSpinner(ref.value);
  } else {
    hideSpinner(ref.value);
  }
});

Pattern 3: Full-Page Loading

onMounted(() => {
  createSpinner({ target: document.body, label: 'Initializing...' });
  showSpinner(document.body);

  initializeApp().finally(() => hideSpinner(document.body));
});

Pattern 4: Spinner with Custom Type

createSpinner({
  target: el,
  type: 'Fluent2',
  width: '40px',
  label: 'Processing...',
  cssClass: 'my-overlay'
});

Key API Quick Reference

Function	Signature	Purpose
createSpinner	(args: SpinnerArgs) => void	Initialize spinner on DOM element
showSpinner	(el: HTMLElement) => void	Show an existing spinner
hideSpinner	(el: HTMLElement) => void	Hide a visible spinner
setSpinner	(args: SetSpinnerArgs) => void	Set global defaults for all spinners

SpinnerArgs properties: target (required), width, label, cssClass, template, type

SpinnerType values: 'Material' | 'Material3' | 'Fabric' | 'Bootstrap' | 'Bootstrap4' | 'Bootstrap5' | 'HighContrast' | 'Tailwind' | 'Tailwind3' | 'Fluent' | 'Fluent2'

Critical Rules

• ❌ No SpinnerComponent class — import { SpinnerComponent } does NOT exist
• ✅ Only use: createSpinner, showSpinner, hideSpinner, setSpinner
• ❌ Do NOT use: color, size, visible, isLoading as SpinnerArgs — they don't exist
• ✅ Valid SpinnerArgs: target, width, label, cssClass, template, type
• ⚠️ Call createSpinner BEFORE showSpinner — order matters
• ⚠️ Put spinner logic in onMounted — the DOM element must exist before calling createSpinner
• ✅ Always call hideSpinner in finally — prevents stuck loading states

Troubleshooting

Issue	Solution
Spinner not showing	Ensure createSpinner is called before showSpinner; check DOM element exists (use onMounted)
Spinner stays visible	Call hideSpinner in finally block; check for unhandled promise rejections
No animation	Verify both ej2-base and ej2-vue-popups CSS imported; ej2-base must come first
TypeScript error	Cast: document.getElementById('id') as HTMLElement or use ref<HTMLDivElement> and null-check
Spinner outside bounds	Add position: relative to target element
Wrong theme	Set type to match your app's CSS theme (e.g., 'Fluent2' for Fluent 2 CSS)

Badge

The Syncfusion Vue 3 Badge is a pure CSS component — no Vue component class to import. Badges are applied by adding CSS modifier classes to a <span> (or <a>) element nested inside the target UI element.

Package: @syncfusion/ej2-vue-notifications

🛑 Agentic use: Do not execute multiple steps autonomously. Confirm with the user before each action (install, run, file creation).

Key Features

• 8 color variants — primary, secondary, success, danger, warning, info, light, dark
• Shape types — circle, pill, link, notification, dot, overlap
• Positioning — top (default) and bottom placement on parent elements
• Customization — custom colors, sizes, and arbitrary positions via CSS
• ListView integration — embed badges in list items with dynamic content
• Reactive Vue 3 — :class binding for dynamic variants driven by ref / computed

Quick Start

1. Install the package:

npm install @syncfusion/ej2-vue-notifications
npm audit

2. Add CSS to src/main.ts:

import '@syncfusion/ej2-base/styles/tailwind3.css';
import '@syncfusion/ej2-vue-notifications/styles/tailwind3.css';

3. Add a badge in your component:

<template>
  <h1>Badge Component <span class="e-badge e-badge-primary">New</span></h1>
</template>

<script setup>
// No component import needed — Badge is CSS-only
</script>

Common Patterns

Notification badge on an icon

<template>
  <!-- Parent must have position: relative -->
  <div class="badge-block">
    <div class="skype svg_icons" />
    <span class="e-badge e-badge-success e-badge-overlap e-badge-notification">99+</span>
  </div>
</template>

Dot status indicator (bottom position)

<template>
  <div class="badge-block">
    <div class="firefox svg_icons" />
    <span class="e-badge e-badge-success e-badge-overlap e-badge-dot e-badge-bottom" />
  </div>
</template>

Pill-shaped label

<template>
  <h1>Messages <span class="e-badge e-badge-primary e-badge-pill">New</span></h1>
</template>

Dynamic color via :class binding

<template>
  <h1>
    Inbox
    <span :class="['e-badge', `e-badge-${color}`, 'e-badge-pill']">
      {{ count }}
    </span>
  </h1>
  <button @click="count++">Increment</button>
</template>

<script setup>
import { ref, computed } from 'vue';

const count = ref(0);
const color = computed(() => (count.value > 5 ? 'danger' : 'primary'));
</script>

CSS Class Reference

Class	Purpose
e-badge	Required base class for all badges
