SvelteKit booking form
Add a booking form to your SvelteKit site with no server route. Collect a preferred date and time in a Svelte component, and requests land in your inbox to confirm. No backend of your own.
How to build it
- Create a form in your Formpaste dashboard and copy its access key.
- Copy the Svelte component above into a SvelteKit page or component.
- Replace YOUR_ACCESS_KEY_HERE with your access key, then deploy.

Add a Formpaste booking request form to my SvelteKit app. Use a Svelte component with name, email, preferred date, preferred time, and notes that POSTs as application/x-www-form-urlencoded (URLSearchParams) to https://api.formpaste.com/submit with a hidden access_key input. No server route. This requests a booking, it does not manage a calendar.Or connect the Formpaste MCP server to Claude Code, Codex, Cursor, Claude Desktop, VS Code, or any mcp-remote client. See the setup guide.
SvelteKit gotchas
SvelteKit gives you server routes and form actions, but for a form you do not need them. A Formpaste form is a Svelte component that posts straight to Formpaste, so there is no +page.server.ts action and no +server.ts route to write. It works with SSR or a static adapter-static build.
No server route or form action needed
You do not need a +page.server.ts action or a +server.ts endpoint. The component posts directly to the Formpaste endpoint, which keeps the app deployable anywhere, including a fully static adapter-static build.
It is a Svelte component
SvelteKit is Svelte, so the form is a single-file component with bind:value and an on:submit|preventDefault handler. Use the Svelte code from the toggle above - it works the same inside SvelteKit.
Progressive enhancement is optional
SvelteKit form actions with use:enhance are great for your own endpoints, but here the endpoint is Formpaste. A plain on:submit|preventDefault fetch is simpler and needs no server code of yours.
SSR or static, same form
Because the form posts to an external endpoint, it works whether you deploy with SSR or as a static site. No server code of yours runs at submit time.
What to get right
A form requests a booking, it does not manage a calendar
This collects a preferred date and time and emails it to you to confirm. It does not check availability or prevent double-booking. If you need live availability, use a scheduling tool and let this form handle the simpler requests.
Spell out the timezone
Put your timezone in the label or a note so a requested time is unambiguous. A booking that is three hours off helps no one.
Confirm before it is real
Treat every submission as a request until you reply to confirm. Set reply-to to the requester so confirming is a single reply.
How it works
Three simple steps for form submissions to land in your email inbox.
Create your form, set your form's action URL to Formpaste's endpoint, and add your access key.
Create your form
Sign up, verify your email, and create an access key in your dashboard.
Copy the code
Paste the snippet above into your project. Pick CSS or Tailwind to match your site.
<script lang="ts">
let status: "idle" | "sending" | "ok" | "error" = "idle";
async function onSubmit(e: SubmitEvent) {
status = "sending";
const form = new FormData(e.target as HTMLFormElement);
const res = await fetch("https://api.formpaste.com/submit", { method: "POST", body: new URLSearchParams(form as any) });
status = res.ok ? "ok" : "error";
}
</script>
{#if status === "ok"}
