Svelte-Specific Features

Reactive Declarations

Use Svelte’s reactive $: syntax:

<script lang="ts">
  export let variant = 'default';
  export let hoverable = false;
  
  $: classes = [
    'card',
    `card--${variant}`,
    hoverable && 'card--hoverable'
  ].filter(Boolean).join(' ');
</script>

<div class={classes}>
  <slot />
</div>

Props

Export variables to create props:

<script lang="ts">
  export let variant: 'elevated' | 'outlined' | 'flat' = 'elevated';
  export let hoverable: boolean = false;
  export let clickable: boolean = false;
</script>

Event Forwarding

Forward DOM events automatically:

<Button on:click on:focus on:blur>
  Click Me
</Button>

Slots

Use Svelte’s slot system:

<Card>
  <slot name="header" />
  <slot />
  <slot name="footer" />
</Card>

Two-Way Binding

Use bind: for two-way data binding:

<script>
  let value = '';
</script>

<Input bind:value placeholder="Enter text" />
<p>You typed: {value}</p>
