Is there a way to import components in svelte dynamically using fetch or import? May be a svelte file or module file created from shareable component (still don't know how that works). very new with svelte and very excited.
I found some code in stackoverflow, which worked for v2. Here is the link
<button on:click="loadChatbox()">
chat to a customer service representative
</button>
{#if ChatBox}
<svelte:component this={ChatBox}/>
{/if}
<script>
export default {
methods: {
async loadChatbox() {
const { default: Chatbox } = await import('./Chatbox.html');
this.set({ Chatbox });
}
}
};
</script>
In React, dynamically importing a component is easy—you invoke React. lazy with the standard dynamic import syntax and specify a fallback UI. When the component renders for the first time, React will load that module and swap it in.
Examples. Next. js supports lazy loading external libraries with import() and React components with next/dynamic . Deferred loading helps improve the initial loading performance by decreasing the amount of JavaScript necessary to render the page.
Dynamic imports or Code Splitting is the practice of breaking up your JavaScript modules into smaller bundles and loading them dynamically at runtime to improve and increase the performance of your website dramatically.
The same functionality exists in Svelte 3, but you only need to assign the dynamically imported component to a regular variable that you use for the this
property on the svelte:component
.
Example (REPL)
<!-- App.svelte -->
<script>
let Chatbox;
function loadChatbox() {
import('./ChatBox.svelte').then(res => Chatbox = res.default)
}
</script>
<button on:click="{loadChatbox}">Load chatbox</button>
<svelte:component this="{Chatbox}" />
<!-- ChatBox.svelte -->
<h1>Dynamically loaded chatbox</h1>
<input />
