Vue file upload form
Build a file upload form in Vue with no backend and no upload API. The component posts multipart FormData straight to Formpaste, so the file lands in your inbox with the other fields. Copy the code and add your access key.
How to build it
- Create a form in your Formpaste dashboard and copy its access key.
- Connect Storage in the dashboard so the form can accept uploads.
- Copy the Vue component above, add your access key, then deploy.

Add a Formpaste file upload form to my Vue 3 app. Use a single-file component with a file input that POSTs the raw FormData (multipart/form-data, not URLSearchParams) to https://api.formpaste.com/submit with a hidden access_key input. Do not build an upload endpoint of my own.Or connect the Formpaste MCP server to Claude Code, Codex, Cursor, Claude Desktop, VS Code, or any mcp-remote client. See the setup guide.
Vue gotchas
A Vue contact form is a single-file component with v-model bindings and an @submit.prevent 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 normal component
The form lives in a .vue single-file component with a <script setup> block. Bind the fields with v-model or read a FormData off the form element on submit, then post to the Formpaste endpoint. No store or plugin 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 in a ref
The endpoint returns JSON (success, message, id). Await the fetch and set a status ref to show your own success or error state, or set a redirect URL in the dashboard and skip the client handling.
Composition or Options API, both work
The examples use <script setup> and the Composition API, but the same fetch works in an Options API component. Formpaste only cares about the POST, not how you structure the component.
What to get right
A file means multipart, not urlencoded
As soon as the form has a file input, it must post multipart form data. The generated code sets enctype and sends the raw FormData, so the file rides along with the other fields. No upload endpoint of your own is needed.
The upload is client to Formpaste, direct
The browser posts the file straight to Formpaste, so your app never buffers or parses the upload. That sidesteps serverless body-size and runtime limits entirely.
Set expectations on size and type
Tell people what you accept. File uploads are a Pro feature; connect Storage in the dashboard first, and keep the input honest about accepted types and size.
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.

<script setup lang="ts">
import { ref } from "vue";
const status = ref<"idle" | "sending" | "ok" | "error">("idle");
async function onSubmit(e: Event) {
status.value = "sending";
const form = new FormData(e.target as HTMLFormElement);
const res = await fetch("https://api.formpaste.com/submit", { method: "POST", body: form });
status.value = res.ok ? "ok" : "error";
}
</script>
