§ 00SvelteKit + Contact Form (with phone)platform-specific integration guide

Why SvelteKit developers choose splitforms for contact form (with phone)

Svelte's lightweight runtime is one of its biggest selling points — adding a heavy form library defeats the purpose. The contact form (with phone) on this page keeps that promise: it uses Svelte's native <code>on:submit</code> directive and a <code>fetch</code> POST, with no external dependencies. The form state lives in a simple <code>let</code> variable, not a store or a state machine. In SvelteKit, you could alternatively use a <code>+page.server.ts</code> action, but that couples your form to SvelteKit's server-side runtime — splitforms decouples it so the same form works on static hosts and other frameworks.

§ 00Quick answerHTML · lead capture

Yes — this is the shortest safe path for SvelteKit.

Use the HTML snippet on this page, keep the contact form (with phone) fields visible in your SvelteKit UI, and let splitforms handle delivery, spam filtering, storage, and webhooks.

best implementation

Paste the HTML version, then replace YOUR_ACCESS_KEY.

The posted payload contains full name, work email, phone, company, what's this about?, message. Required fields are full name, work email, phone, what's this about? and message.

native sveltekit reality

use case fit

A contact form with a phone number field that auto-formats as the user types — (555) 123-4567 emerges from raw digits. Pure pattern validation, optional JS mask for the live formatting.

§ 03bPhone Number Input Form (with masked input)template-specific playbook

The reason this contact form (with phone) exists.

Mobile-friendly numeric keypad, live mask, format-tolerant.

why it matters

Phone fields suffer from format chaos — users type +1 555 123 4567, (555) 123 4567, 555.123.4567, 5551234567. Three options: accept anything and normalize server-side (best for international), use a pattern attribute for client-side validation (good for US-only), or apply a JavaScript mask that formats as the user types (highest conversion, more code). splitforms accepts any format and your form's UX is whichever approach fits your audience.

route the submission

Use type="tel" not type="text"

Mobile keyboards open the numeric keypad for tel inputs. Desktop accepts the same characters as text but signals intent.

Add a pattern attribute for validation

`pattern="[0-9() +-]+"` allows the common phone characters. Or use a strict US format: `pattern="$?\d{3}$?[ -]?\d{3}[ -]?\d{4}"`.

(Optional) Add the JS mask

On input, strip non-digits and reformat to `(XXX) XXX-XXXX`. The mask runs on every keystroke, giving live formatting feedback.

§ 03cSvelteKit production notesnative path · deploy · gotchas

What changes when this contact form (with phone) lives in SvelteKit.

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

without splitforms

SvelteKit's headline form story is form actions — write a default-exported actions object in +page.server.ts, and SvelteKit handles FormData parsing, progressive enhancement (use:enhance), and result passing via the form prop. It's elegant DX — but it doesn't deliver email. You still write the SMTP integration, the spam-filter logic, the database for storing submissions, the webhook fan-out. The result is a form action that's ~80% boilerplate and ~20% your business logic. Splitforms collapses the boilerplate: the form posts directly from the browser to splitforms.com, the form action becomes a thin proxy (or you skip it entirely), and the operational layer disappears.

deploy notes

SvelteKit's adapter system is the deployment story: @sveltejs/adapter-vercel, -netlify, -cloudflare, -cloudflare-workers, -node, -static. The form's POST is cross-origin to splitforms regardless of adapter. On Cloudflare Pages/Workers (free tier: 10ms CPU per request), avoid Pattern B — the form action's fetch round-trip eats your budget; use Pattern A. On Vercel/Netlify, both patterns work with no measurable difference. $env/static/public inlines at build time (use for client-exposed keys); $env/static/private is server-only (use for Pattern B's server-action key). Domain-lock the access key.

SvelteKit gotcha

Form actions need POST and the named action prefix

If you use +page.server.ts form actions, the form's action attribute must be ?/contact (or whatever you named it) — not /api/contact. Forgetting the ?/ prefix routes to a 404 because SvelteKit doesn't recognize it as an action.

SvelteKit gotcha

use:enhance disables your client-side handler if you don't return a callback

use:enhance without arguments uses default progressive-enhancement behavior — which calls the form action and re-renders. If you need custom logic (toast on error, etc.), return a function: use:enhance={({ formData, cancel }) => async ({ result }) => …}.

SvelteKit gotcha

Cloudflare adapter has a 50ms cold start budget — fetch to splitforms eats it

If you use a SvelteKit form action that proxies to splitforms.com via fetch, the round-trip eats your CF Worker time budget on cold start. Skip the proxy: have the form POST directly to splitforms.com from the client (the snippet above does this).

SvelteKit gotcha

$env/static/public vs $env/dynamic/public — pick the right one

$env/static/public is inlined at build time (faster, but key is in the bundle). $env/dynamic/public is read at runtime (slower, but rotatable without rebuild). For the splitforms key, static is fine if you've locked the key to your domain.

PATTERN A

Pattern A — client-side fetch (skip form actions)

Pure +page.svelte with a fetch handler — no +page.server.ts needed. Simpler, works on every adapter without server CPU time, no proxying. Best for Cloudflare Workers / Pages where CPU budget matters. Use the same wiring for the contact form (with phone) fields on this page.

pattern-a.txtsvelte14 lines

01<script>
02  let status = "idle";
03  async function onSubmit(e) {
04    status = "loading";
05    const fd = new FormData(e.currentTarget);
06    fd.append("access_key", import.meta.env.VITE_PUBLIC_SPLITFORMS_KEY);
07    const r = await fetch("https://splitforms.com/api/submit", { method: "POST", body: fd });
08    status = (await r.json()).success ? "ok" : "err";
09  }
10</script>
11<form on:submit|preventDefault={onSubmit}>
12  <input name="email" type="email" required />
13  <button disabled={status === "loading"}>Send</button>
14</form>

PATTERN B

Pattern B — form action with use:enhance (no-JS support)

Server-side form action proxies to splitforms; key stays in $env/static/private. With use:enhance, the form posts traditionally without JS (full-page reload, splitforms 302 to /thanks) and AJAXes when JS loads. Maximum compatibility, slight CPU cost on the server. Use the same wiring for the contact form (with phone) fields on this page.

pattern-b.txtsvelte12 lines

01// +page.server.ts
02import { fail, redirect } from "@sveltejs/kit";
03import { SPLITFORMS_KEY } from "$env/static/private";

05  default: async ({ request }) => {
06    const fd = await request.formData();
07    fd.append("access_key", SPLITFORMS_KEY);
08    const r = await fetch("https://splitforms.com/api/submit", { method: "POST", body: fd });

§ 06Questions9 answered

Contact Form (with phone) on SvelteKit — FAQ.

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

01Does this contact form (with phone) work on SvelteKit?

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

02How much does the contact form (with phone) cost on SvelteKit?

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 (full name, work email, phone, company…) — add, remove, or rename any of them. Splitforms accepts whatever fields you POST.

04How does spam protection work on the contact form (with phone)?

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 SvelteKit as on any other framework.

05Can I send the contact form (with phone) 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 SvelteKit 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 use type="tel" if it doesn't do anything special on desktop?

Two reasons. (1) Mobile keyboards: tel triggers the numeric keypad, dramatically reducing typos. (2) Accessibility: screen readers announce the field type, helping users with assistive tech understand what's expected. The 'no desktop benefit' is a feature, not a bug — the behavior matches user intent.

08Should I validate international or US-only?

Depends on your audience. International contact forms should accept any format (use a permissive pattern + server-side normalization). US-only forms can use a strict pattern that matches `(555) 123-4567`. Either way, splitforms accepts whatever format the user submits — the validation is for UX, not data integrity.

09Does the JS mask work with paste?

Yes — listen for both `input` and `paste` events, and reformat on every change. The pattern only validates on submit, so the mask gives live feedback as the user types or pastes.
