Dynamically loading component using import or fetch

Question

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>

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 />
