# React Router quickstart

Add a working contact form to a React Router app. You write the form, and Formerie checks it, stores it, and emails you.

## Install

npm:

```sh
npm install @formerie/react @formerie/client
```

pnpm:

```sh
pnpm add @formerie/react @formerie/client
```

Yarn:

```sh
yarn add @formerie/react @formerie/client
```

Bun:

```sh
bun add @formerie/react @formerie/client
```

Formerie packages are in alpha, so APIs can still change between releases.

## Add the form

Use this as a route component, such as `app/routes/contact-form.tsx`.

```tsx
import { useFormerieSubmit } from "@formerie/react";

export default function ContactForm() {
  const { submit, state } = useFormerieSubmit({ workspace: "acme", form: "contact" });

  return (
    <form
      onSubmit={(event) => {
        event.preventDefault();
        submit({ fields: Object.fromEntries(new FormData(event.currentTarget)) });
      }}
    >
      <input name="name" placeholder="Name" required />
      <input name="email" type="email" placeholder="Email" required />
      <textarea name="message" placeholder="Message" required />
      <button disabled={state.status === "submitting"}>Send</button>
      {state.result?.ok === true && <p>Thanks!</p>}
      {state.result?.ok === false && <p>{state.result.error.message}</p>}
    </form>
  );
}
```

Each input's `name` is the field it fills in Formerie.

## Set up the form in the app

1. Open [app.formerie.com](https://app.formerie.com) and create a form named **Contact**. It comes with the
   name, email, and message fields this code sends.
2. On the **Delivery** tab, add your email address, then choose **Save delivery**. Confirm the email
   Formerie sends you.
3. On the **Publish** tab, choose **API-only** and add the address your dev server prints, such as `http://localhost:5173`, under
   **Your website addresses**. `localhost` and `127.0.0.1` count as different addresses. Add your live site's address the
   same way when you deploy.
4. Choose **Publish form**.
5. In the code above, replace `acme` with the workspace handle shown on the **Publish** tab.

## Check it arrived

Run your app, fill in the form, and send it. "Thanks!" appears on the page. In the app, your response shows
under **Submissions**, and its email under **Deliveries**.

Seeing a CORS error, or `NETWORK_ERROR`? Your site's address isn't on the **Publish** tab yet, or you haven't published since adding it.
See [Troubleshooting](/guides/troubleshooting/).

## Going further

### From your server

Use a route action, and a native form can post to it. Read [what the server path costs](/guides/framework-entry-points/#from-your-server)
before you choose it.

```ts
import { FormerieRuntimeClient } from "@formerie/client";
import type { Route } from "./+types/contact";

const formerie = new FormerieRuntimeClient();

export async function action({ request }: Route.ActionArgs) {
  const fields = Object.fromEntries(await request.formData());

  return formerie.submit("acme", "contact", { fields });
}
```
