# Nuxt

import { Tabs, TabItem } from '@astrojs/starlight/components';

This guide shows how to initialize and deploy a Nuxt 3 application to Cloudflare using Alchemy.

## Init

Start by creating a new Nuxt project with Alchemy:

<Tabs syncKey="pkgManager">
  <TabItem label="bun">
    ```sh
    bunx alchemy create my-nuxt-app --template=nuxt
    cd my-nuxt-app
    ```
  </TabItem>
  <TabItem label="npm">
    ```sh
    npx alchemy create my-nuxt-app --template=nuxt
    cd my-nuxt-app
    ```
  </TabItem>
  <TabItem label="pnpm">
    ```sh
    pnpm dlx alchemy create my-nuxt-app --template=nuxt
    cd my-nuxt-app
    ```
  </TabItem>
  <TabItem label="yarn">
    ```sh
    yarn dlx alchemy create my-nuxt-app --template=nuxt
    cd my-nuxt-app
    ```
  </TabItem>
</Tabs>

## Login

Authenticate once with your Cloudflare account:

<Tabs syncKey="pkgManager">
  <TabItem label="bun">
    ```sh
    bun alchemy login
    ```
  </TabItem>
  <TabItem label="npm">
    ```sh
    npx alchemy login
    ```
  </TabItem>
  <TabItem label="pnpm">
    ```sh
    pnpm alchemy login
    ```
  </TabItem>
  <TabItem label="yarn">
    ```sh
    yarn alchemy login
    ```
  </TabItem>
</Tabs>

:::tip
Alchemy login creates Cloudflare OAuth tokens for alchemy. See the [Cloudflare](/guides/cloudflare) guide for other options.
:::

## Deploy

Run the deploy script generated by the template:

<Tabs syncKey="pkgManager">
  <TabItem label="bun">
    ```sh
    bun run deploy
    ```
  </TabItem>
  <TabItem label="npm">
    ```sh
    npm run deploy
    ```
  </TabItem>
  <TabItem label="pnpm">
    ```sh
    pnpm run deploy
    ```
  </TabItem>
  <TabItem label="yarn">
    ```sh
    yarn run deploy
    ```
  </TabItem>
</Tabs>

You'll get the live URL of your Nuxt site:

```sh
{
  url: "https://website.<your-account>.workers.dev"
}
```

## Local Development

Work locally using the dev script:

<Tabs syncKey="pkgManager">
  <TabItem label="bun">
    ```sh
    bun run dev
    ```
  </TabItem>
  <TabItem label="npm">
    ```sh
    npm run dev
    ```
  </TabItem>
  <TabItem label="pnpm">
    ```sh
    pnpm run dev
    ```
  </TabItem>
  <TabItem label="yarn">
    ```sh
    yarn run dev
    ```
  </TabItem>
</Tabs>

## Destroy

Clean up all Cloudflare resources created by this stack:

<Tabs syncKey="pkgManager">
  <TabItem label="bun">
    ```sh
    bun run destroy
    ```
  </TabItem>
  <TabItem label="npm">
    ```sh
    npm run destroy
    ```
  </TabItem>
  <TabItem label="pnpm">
    ```sh
    pnpm run destroy
    ```
  </TabItem>
  <TabItem label="yarn">
    ```sh
    yarn run destroy
    ```
  </TabItem>
</Tabs>

## What files are created

### `.env`

Alchemy requires a locally set password to encrypt Secrets that are stored in state. Be sure to change this.

:::note
See the [Secret](/concepts/secret) documentation to learn more.
:::

```
ALCHEMY_PASSWORD=change-me
```

### `alchemy.run.ts`

```typescript
import alchemy from "alchemy";
import { Nuxt } from "alchemy/cloudflare";

const app = await alchemy("my-nuxt-app");

export const worker = await Nuxt("website");

console.log({
  url: worker.url,
});

await app.finalize();
```

### `types/env.d.ts`

```typescript
// Auto-generated Cloudflare binding types.
// @see https://alchemy.run/concepts/bindings/#type-safe-bindings

import type { worker } from "../alchemy.run.ts";

export type CloudflareEnv = typeof worker.Env;

declare global {
  type Env = CloudflareEnv;
}

declare module "cloudflare:workers" {
  namespace Cloudflare {
    export interface Env extends CloudflareEnv {}
  }
}
```

### `tsconfig.json`

The CLI updated the `tsconfig.json` to include `alchemy.run.ts` and register `@cloudflare/workers-types` + `types/env.d.ts` globally:

```json
{
  "extends": "@nuxtjs/module-builder/tsconfig.json",
  "include": ["**/*", "alchemy.run.ts"],
  "exclude": ["dist"],
  "compilerOptions": {
    "types": ["@cloudflare/workers-types", "./types/env.d.ts"]
  }
}
```

### `nuxt.config.ts`

Use the `cloudflare-module` preset and `nitro-cloudflare-dev` module to build for Cloudflare in production and development:

```typescript
import alchemy from "alchemy/cloudflare/nuxt";
import { defineNuxtConfig } from "nuxt/config";

export default defineNuxtConfig({
  devtools: { enabled: true },
  nitro: {
    preset: "cloudflare-module",
    cloudflare: alchemy(),
    prerender: {
      routes: ["/"],
      autoSubfolderIndex: false,
    },
  },
  modules: ["nitro-cloudflare-dev"],
});
``` 

:::tip
The `alchemy()` function from `alchemy/cloudflare/nuxt` is used to configure Nuxt for local development.
:::

:::warning
If you run `nuxt dev` without first running Alchemy, you will get an error from `nitroCloudflareDev()`. This is because Alchemy needs to be run first to create the local environment. We recommend running `alchemy dev`, which runs `nuxt dev` automatically.
