suspense component in vuejs

 Sure, here's an example of how to use the Suspense component in Vue 3 to handle asynchronous components:

First, let's create a component that will be loaded asynchronously. We'll call it AsyncComponent.vue

<template>

<div>

<h2>Hello from AsyncComponent!</h2>

</div>

</template>

<script>

export default {

name: 'AsyncComponent',

async setup() {

// Simulate async operation

await new Promise(resolve => setTimeout(resolve, 2000));

}

}

</script>

Next, let's create the parent component that will use the Suspense component to handle the asynchronous loading of AsyncComponent.vue. We'll call it ParentComponent.vue:

<template>

<div>

<h1>Hello from ParentComponent!</h1>

<Suspense>

<template #default>

<AsyncComponent />

</template>

<template #fallback>

<div>Loading...</div>

</template>

</Suspense>

</div>

</template>

<script>

import AsyncComponent from './AsyncComponent.vue';

export default {

name: 'ParentComponent',

components: {

AsyncComponent

}

}

</script>

In this example, the Suspense component is used to wrap the AsyncComponent. The #default slot is used to display the AsyncComponent when it's loaded, and the #fallback slot is used to display a loading message while the AsyncComponent is being loaded.

When you run this code, you should see the "Loading..." message for 2 seconds, and then the "Hello from AsyncComponent!" message will appear.
