How do I show a thank-you state?

Flip a reactive `status` variable based on the JSON FormLoom returns.

Svelte guide

If you're using Svelte without SvelteKit (e.g. embedded in another app), you still get a clean contact form: an `on:submit` handler, a `fetch`, and a reactive status. FormLoom handles storage, spam, and email.

Approach

Bind `on:submit` with a handler that serializes the form and POSTs to FormLoom. Use a reactive `status` variable for the UI.

Code

src/routes/contact/+page.svelte

<!-- src/routes/contact/+page.svelte -->
<script>
  let status = "idle";
  async function submit(e) {
    e.preventDefault();
    const res = await fetch("https://formloom.vercel.app/api/submit/YOUR_ACCESS_KEY", {
      method: "POST",
      headers: { "Content-Type": "application/json", Accept: "application/json" },
      body: JSON.stringify(Object.fromEntries(new FormData(e.target))),
    });
    status = (await res.json()).success ? "ok" : "error";
  }
</script>

{#if status === "ok"}
  <p>Thanks — we got your message.</p>
{:else}
  <form on:submit={submit}>
    <label>
      Name
      <input type="text" name="name" required />
    </label>
    <label>
      Email
      <input type="email" name="email" required />
    </label>
    <label>
      Message
      <textarea name="message" required placeholder="How can we help?"></textarea>
    </label>
    <!-- honeypot: bots fill this, humans don't see it -->
    <input type="checkbox" name="botcheck" style="display:none" tabindex="-1" autocomplete="off" />
    <button type="submit">Send</button>
  </form>
{/if}

contact.html

<form action="https://formloom.vercel.app/api/submit/YOUR_ACCESS_KEY" method="POST">
  <label>
    Name
    <input type="text" name="name" required />
  </label>
  <label>
    Email
    <input type="email" name="email" required />
  </label>
  <label>
    Message
    <textarea name="message" required placeholder="How can we help?"></textarea>
  </label>
  <!-- honeypot: bots fill this, humans don't see it -->
  <input type="checkbox" name="botcheck" style="display:none" tabindex="-1" autocomplete="off" />
  <button type="submit">Send</button>
</form>

submit.ts

// npm i @formloom/client
import { createForm } from "@formloom/client";

type Contact = {
  name: string;
  email: string;
  message: string;
};

const form = createForm<Contact>("YOUR_ACCESS_KEY");

// End-to-end typed: TS errors if you send the wrong shape.
const { success, message } = await form.submit({
  name: form.name.value,
  email: form.email.value,
  message: form.message.value,
});

Gotchas

Call `e.preventDefault()` in your handler.
Without SvelteKit there's no server action — the client fetch is the integration.

FAQ

No. A plain Svelte component with a client fetch works anywhere Svelte runs.
