# Vue

> A Vue single-file component that submits to Ikiform, plus a Nuxt server route with a secret key.

Vue posts from the browser with the SDK or `fetch`. No plugin or build step is needed beyond your usual setup.

## Install the SDK

`Terminal`:

```bash
npm install @ikiform/sdk
```

## A single-file component

`ContactForm.vue`:

```vue
<script setup>
import { submit } from "@ikiform/sdk";
import { ref } from "vue";

const status = ref("idle");
const errors = ref({});
const message = ref("");

async function onSubmit(event) {
  status.value = "sending";
  const result = await submit("frm_xxxxxxxxxxxxxxxx", new FormData(event.target));
  if (result.ok) {
    status.value = "sent";
    return;
  }
  errors.value = result.error.fields ?? {};
  message.value = result.error.message;
  status.value = "error";
}
</script>

<template>
  <p v-if="status === 'sent'">Thanks, we got it.</p>
  <form v-else @submit.prevent="onSubmit">
    <label>
      Email
      <input name="email" type="email" required />
    </label>
    <p v-if="errors.email">{{ errors.email[0] }}</p>
    <label>
      Message
      <textarea name="message"></textarea>
    </label>
    <input name="_gotcha" type="text" tabindex="-1" autocomplete="off" hidden />
    <p v-if="status === 'error' && !errors.email" role="alert">{{ message }}</p>
    <button :disabled="status === 'sending'">Send</button>
  </form>
</template>
```

For forms with the **Ikiform** human check, call `challenge(formId)` before `submit` and pass the token as `{ turnstileToken }`, as in the [React guide](https://ikiform.com/docs/guides/react.md#component).

## Nuxt server route

To post from the server instead, add a server route that forwards the body with a secret key. The page then posts JSON to your own route.

`server/api/contact.post.ts`:

```ts
export default defineEventHandler(async (event) => {
  const body = await readBody(event);
  return $fetch("https://ikiform.com/f/frm_xxxxxxxxxxxxxxxx", {
    method: "POST",
    headers: { Authorization: `Bearer ${process.env.IKIFORM_SECRET_KEY}` },
    body,
    ignoreResponseError: true,
  });
});
```

> Posts sent from your server all come from your server's IP address, so Ikiform's per-visitor rate limits count every visitor together. The Standard preset allows 5 posts a minute per IP and form, which a busy site can hit. Post from the browser when you can, or choose the Relaxed or Custom [rate limit](https://ikiform.com/docs/rate-limits.md) for forms you proxy through a server.
