Svelte Components

Quick Start

Component libraries: Bits UI (headless) | Ark UI | Melt UI (primitives)

Form trick: Use form attribute when form can't wrap inputs:

Copy<form id="my-form" action="/submit"><!-- outside table --></form>
<table>
	<tr>
		<td><input form="my-form" name="email" /></td>
		<td><button form="my-form">Submit</button></td>
	</tr>
</table>

Web Components

Copy// svelte.config.js
export default {
	compilerOptions: {
		customElement: true,
	},
};

Copy<!-- MyButton.svelte -->
<svelte:options customElement="my-button" />

<button><slot /></button>
