§ 00React + Event RSVPplatform-specific integration guide

Why React developers choose splitforms for event rsvp

React ships nothing for form delivery — it's a view layer. The historical options are an Express server you stand up just for POST /api/contact, a Vercel serverless function with SMTP wiring, or a third-party library like Formik that still leaves the backend problem unsolved. The event rsvp on this page uses <code>useState</code> for submit state and a plain <code>fetch</code> POST to splitforms — no form library, no context provider, no wrapper component. It works in Create React App, Vite, Remix, and every React bundler because it's just standard <code>FormData</code> and the Fetch API.

§ 00Quick answerReact / Next.js · events

Yes — this is the shortest safe path for React.

Use the React / Next.js snippet on this page, keep the event rsvp fields visible in your React UI, and let splitforms handle delivery, spam filtering, storage, and webhooks.

best implementation

Paste the React / Next.js version, then replace YOUR_ACCESS_KEY.

The posted payload contains your name, email, will you attend?, how many guests are you bringing?, dietary preferences. Required fields are your name, email and will you attend?.

native react reality

React itself ships nothing for form submission — it's a view layer.

use case fit

Eventbrite charges 3.7% + $1.79 per ticket. For a free event, fundraiser, or private gathering, the RSVP form does the same job for $0 — and lives on your own domain.

Loved the demo — quick question about pricing on the 3-year plan. Are usage limits per project or account-wide?

§ 03bEvent RSVP Form (Public / Private Events)template-specific playbook

The reason this event rsvp exists.

Webhooks into Notion / Airtable / Google Sheets · auto .ics calendar invite.

why it matters

Eventbrite, Splash, and Hopin take 3-7% of every paid ticket and charge subscription fees for the white-label option. For free events (fundraisers, private parties, conferences with sponsor-only revenue, weddings), the platform fees are pure waste. The RSVP form captures attending yes/no, guest count, plus-one names, dietary restrictions, and any custom fields (workshop preference for conferences, song requests for weddings). Webhook to a Notion / Airtable / Google Sheet for the running headcount, plus an automatic confirmation email. Final headcount goes to catering 5-7 days out, same as any platform would deliver.

route the submission

Capture attendance and party

Required: attending yes/no, guest count, plus-one names if applicable. Optional: dietary restrictions, song requests, workshop preference, accessibility needs.

Update the running list

Webhook to a Notion / Airtable / Google Sheet that the host references. Each RSVP appends a row; conditional formatting highlights special diets. Real-time headcount without spreadsheet work.

Confirm via email

Auto-respond with confirmation, event details, and a calendar invite (.ics file). Most guests forget the date once they've RSVP'd — calendar adds reduce no-shows by 30-40%.

§ 03cReact production notesnative path · deploy · gotchas

What changes when this event rsvp lives in React.

These notes come from the React platform registry and are rendered on this template page so crawlers see the framework-specific answer without opening a separate guide.

without splitforms

React itself ships nothing for form submission — it's a view layer. The historical baseline is one of: an Express/Hono/Fastify server you stand up just for POST /api/contact, a Function-as-a-Service (Vercel/Netlify/Cloudflare) that ends up needing the same SMTP wiring, or a third-party form library (React Hook Form, Formik) that handles validation but still leaves you to operate the backend. Vite, CRA, and Remix all default to assuming you have somewhere to POST — they just don't tell you where. Splitforms is the where: a single fetch call, no library install, no useEffect gymnastics, no Express boilerplate.

deploy notes

Vite-built React apps are static — they deploy to any static host (Vercel, Netlify, Cloudflare Pages, S3, GitHub Pages). The splitforms fetch is cross-origin, so configure your CSP to allow connect-src 'self' https://splitforms.com if you have one. Vite reads env vars from .env at build time and only exposes those prefixed VITE_ to the browser bundle. CRA uses REACT_APP_ instead. On Cloudflare Pages, the build output is served from the edge with sub-50ms cold starts; splitforms adds another ~30ms RTT — not noticeable in practice. Lock the access key to your live origin in the splitforms dashboard.

React gotcha

useState + setStatus inside async causes race conditions

If a user double-clicks submit before the first request settles, you'll fire two POSTs. Always disable the button while status === 'loading'. Better still, also use an AbortController to cancel the in-flight request if a re-submit happens.

React gotcha

FormData and controlled inputs can desync

If you control inputs via useState (value={name} onChange={...}), the FormData object you build with new FormData(e.target) won't see your state — it reads the actual DOM. Either use uncontrolled inputs (no value prop) or build the body manually from state.

React gotcha

CSP errors when posting to a third-party endpoint

If your site has a strict Content Security Policy with connect-src 'self', fetch to splitforms.com will be blocked. Add splitforms.com to your connect-src directive: connect-src 'self' https://splitforms.com.

React gotcha

Strict mode + double-mount triggers two submissions in dev

React 18+ strict mode mounts components twice in development to surface side effects. If you put your fetch call in useEffect (don't), you'll see double-submits. Always trigger network calls in event handlers, not effects.

PATTERN A

Pattern A — uncontrolled inputs + native FormData

Skip useState per field. Inputs stay uncontrolled, new FormData(e.currentTarget) reads them at submit time, status state covers idle/loading/ok/err. ~25 lines, no form library. Use the same wiring for the event rsvp fields on this page.

pattern-a.jsxjsx17 lines

01import { useState } from "react";
02export default function ContactForm() {
03  const [status, setStatus] = useState("idle");
04  return (
05    <form onSubmit={async (e) => {
06      e.preventDefault(); setStatus("loading");
07      const fd = new FormData(e.currentTarget);
08      fd.append("access_key", import.meta.env.VITE_SPLITFORMS_KEY);
09      const r = await fetch("https://splitforms.com/api/submit", { method: "POST", body: fd });
10      setStatus((await r.json()).success ? "ok" : "err");
11    }}>
12      <input name="email" type="email" required />
13      <textarea name="message" required />
14      <button disabled={status === "loading"}>Send</button>
15    </form>
16  );
17}

PATTERN B

Pattern B — React Hook Form for validation, splitforms for delivery

RHF handles client-side validation (zod schema, error messages); on valid submit, hand off to splitforms. RHF's handleSubmit callback receives parsed values — repackage as FormData and POST. Use the same wiring for the event rsvp fields on this page.

pattern-b.jsxjsx8 lines

01import { useForm } from "react-hook-form";
02const { register, handleSubmit, formState } = useForm();
03const onSubmit = async (data) => {
04  const fd = new FormData();
05  Object.entries(data).forEach(([k, v]) => fd.append(k, v));
06  fd.append("access_key", import.meta.env.VITE_SPLITFORMS_KEY);
07  await fetch("https://splitforms.com/api/submit", { method: "POST", body: fd });
08};

§ 06Questions9 answered

Event RSVP on React — FAQ.

Direct answers, no marketing fluff. Missing one? Email hello@splitforms.com.

01Does this event rsvp work on React?

Yes. The form is plain HTML with a single POST endpoint, so it runs on any React site without server-side code, plugins, or SDKs. Drop the snippet into a React page or component and submissions land in your splitforms dashboard.

02How much does the event rsvp cost on React?

Free for 500 submissions per month — no credit card, no trial. Pro is $5/mo for 5,000 submissions, and there's a one-time $59 3-year plan (15,000 submissions/mo for 36 months). The same pricing applies regardless of which framework hosts the form.

03Can I customize the fields?

Yes. The template ships with sensible defaults (your name, email, will you attend?, how many guests are you bringing?…) — add, remove, or rename any of them. Splitforms accepts whatever fields you POST.

04How does spam protection work on the event rsvp?

A hidden honeypot field catches dumb bots, and a tuned classifier scores the rest. You only see real submissions in your dashboard. No CAPTCHA, no friction for human users — and it works the same on React as on any other framework.

05Can I send the event rsvp submissions to Slack or Discord?

Yes. Webhooks are available on Starter and above, with auto-formatted payloads for Slack, Discord, and WhatsApp (via CallMeBot). Or send raw signed JSON to any URL — Zapier, n8n, your own server. Configure in the splitforms dashboard.

06Will it work on a static React site?

Yes — the form posts directly to splitforms from the browser, so no server is involved. Works on Vercel, Netlify, GitHub Pages, Cloudflare Pages, S3, or any plain Apache host.

07Why not just use Eventbrite or Splash?

For free events, both charge subscription fees ($30-100/mo for white-label) plus per-ticket fees. The form costs $0, lives on your own domain (which matters for weddings and brand events), and the data is yours — not licensed inside their platform.

08Can I send a calendar invite (.ics) automatically?

Yes — generate an .ics file and attach to the auto-responder. Webhook to a Zapier / Make automation that crafts the .ics with event title, date, location, and notes. Most email clients render the attachment as 'add to calendar' inline.

09How do I handle plus-ones?

Add 'plus-one yes/no' and a name field that appears conditionally. For weddings, the 'plus-one allowed' is invitation-specific — capture invitation code on the form, and the webhook validates whether that invite includes a plus-one before accepting the second name.
