Does it work with SolidStart?

Yes — you can also forward from a SolidStart server action if you want server-side handling.

SolidJS guide

SolidJS uses fine-grained reactivity but the form pattern is the same: an `onSubmit` handler, a `fetch`, and a signal for status. FormLoom handles the rest.

Approach

Use `onSubmit` with `createSignal` for status. Serialize with `FormData` and POST JSON.

Code

ContactForm.tsx

// ContactForm.tsx — React (works in Vite, CRA, Next 'use client')
"use client";
import { useState } from "react";

export function ContactForm() {
  const [status, setStatus] = useState<"idle" | "ok" | "error">("idle");

  async function onSubmit(e: React.FormEvent<HTMLFormElement>) {
    e.preventDefault();
    const form = e.currentTarget;
    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(form))),
    });
    setStatus((await res.json()).success ? "ok" : "error");
    if (status !== "error") form.reset();
  }

  if (status === "ok") return <p>Thanks — we got your message.</p>;
  return (
    <form onSubmit={onSubmit}>
      <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,
});

contact.html

<form id="contact-form">
  <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>

<script>
const form = document.getElementById("contact-form");
form.addEventListener("submit", async (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(form))),
  });
  const data = await res.json();
  if (data.success) {
    form.reset();
    alert("Thanks — we got your message.");
  } else {
    alert(data.message || "Something went wrong.");
  }
});
</script>

Gotchas

Call `e.preventDefault()` in the handler.
Use a signal (`createSignal`) for the status UI, not React-style `useState`.

FAQ

Mostly the same JSX; use `createSignal` instead of `useState` for the status.
