Svelte survey form
Build a survey form in Svelte with no backend. Use dropdowns for quick answers and one open field, bound with bind:value, then post to Formpaste. Copy the component and add your access key - responses land in your inbox.
How to build it
- Create a form in your Formpaste dashboard and copy its access key.
- Copy the Svelte component above and pick your styling.
- Replace YOUR_ACCESS_KEY_HERE with your access key, then deploy.

Add a Formpaste survey form to my Svelte app. Use a single-file component with a couple of select dropdowns and a textarea, bound with bind:value, that POSTs as application/x-www-form-urlencoded (URLSearchParams) to https://api.formpaste.com/submit with a hidden access_key input. No backend.Or connect the Formpaste MCP server to Claude Code, Codex, Cursor, Claude Desktop, VS Code, or any mcp-remote client. See the setup guide.
Svelte gotchas
A Svelte contact form is a single-file component with bind:value on the fields and an on:submit|preventDefault handler that posts to Formpaste. There is no backend and no API of your own. Put the fetch in the component and you are done.
It is a single-file component
The form lives in a .svelte component with a <script> block. Bind the fields with bind:value or read a FormData off the form element on submit, then post to the Formpaste endpoint. No store or library is required for a simple form.
No API of your own
You do not proxy through your own server. The component posts straight to the Formpaste endpoint, which removes a mailer and a submissions store you would otherwise build.
Handle the response with a reactive status
The endpoint returns JSON (success, message, id). Await the fetch and set a reactive status variable to show your own success or error state, or set a redirect URL in the dashboard and skip the client handling.
Svelte 4 or Svelte 5, both work
The examples use a <script> block with a plain status variable, which works in every Svelte version. On Svelte 5 you can use runes like $state instead, but the same fetch and the same POST are all Formpaste needs.
What to get right
Keep it short to keep completion high
Every extra question loses responses. A couple of dropdowns and one open comment field usually gathers what you need without fatigue.
Dropdowns beat free text for analysis
Fixed choices (select fields) are easy to count later. Reserve the textarea for the one open-ended question that genuinely needs it.
Make email optional for honest answers
Anonymous responses are often more candid. Ask for email only if you need to follow up, and mark it optional.
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"}
