A page that only has a single action is, in practice, quite rare. Most of the time you'll need to have multiple actions on a page. In this app, creating a todo isn't enough — we'd like to delete them once they're complete.

Begin by replacing our default action with named create and delete actions:

src/routes/+page.server.js
export const actions = {
	create: async ({ cookies, request }) => {
		const data = await request.formData();
		db.createTodo(cookies.get('userid'), data.get('description'));
	},

	delete: async ({ cookies, request }) => {
		const data = await request.formData();
		db.deleteTodo(cookies.get('userid'), data.get('id'));
	}
};

Default actions cannot coexist with named actions.

The <form> element has an optional action attribute, which is similar to an <a> element's href attribute. Update the existing form so that it points to the new create action:

src/routes/+page.svelte
<form method="POST" action="?/create">
	<label>
		add a todo:
		<input
			name="description"
			autocomplete="off"
		/>
	</label>
</form>

The action attribute can be any URL — if the action was defined on another page, you might have something like /todos?/create. Since the action is on this page, we can omit the pathname altogether, hence the leading ? character.

Next, we want to create a form for each todo, complete with a hidden <input> that uniquely identifies it:

src/routes/+page.svelte
<ul class="todos">
	{#each data.todos as todo (todo.id)}
		<li>
			<form method="POST" action="?/delete">
				<input type="hidden" name="id" value={todo.id} />
				<span>{todo.description}</span>
				<button aria-label="Mark as complete"></button>
			</form>
		</li>
	{/each}
</ul>
