# Deploy SvelteKit to Bunny Storage

> Build a SvelteKit site and serve it from Bunny Storage through Bunny CDN, with the Bunny CLI or by hand.

export const build_0 = "npm run build"

SvelteKit's static adapter prerenders your app into `build`.

| Setting | Value |
| - | - |
| Build command | `npm run build` |
| Output directory | `build` |

## Configure SvelteKit

Install the static adapter:

```bash theme={null}
npm install -D @sveltejs/adapter-static
```

Use it in `svelte.config.js`:

```js svelte.config.js theme={null}
import adapter from "@sveltejs/adapter-static";

/** @type {import('@sveltejs/kit').Config} */
const config = {
  kit: {
    adapter: adapter(),
  },
};

export default config;
```

Then prerender every page, and write each one as a folder with an `index.html`, in `src/routes/+layout.js`:

```js src/routes/+layout.js theme={null}
export const prerender = true;
export const trailingSlash = "always";
```

Without `trailingSlash`, SvelteKit writes `/about` as `about.html`, and a request for `/about` returns a 404.

## Deploy your site

<Tabs>
  <Tab title="Bunny CLI">
    <Warning>
      `bunny sites` is in [Public Preview](/docs/product-release-stages#stage-2-public-preview)
      and available only in the Bunny CLI. It's in active development, so commands,
      flags, and behaviour may change. Share feedback on
      [Discord](https://discord.gg/bunnynet). The storage zone and pull zone behind
      each site appear in the dashboard under **Storage** and **CDN**.
    </Warning>

    <Steps>
      <Step title="Install the Bunny CLI and log in">
        ```bash theme={null}
        curl -fsSL https://cli.bunny.net/install.sh | sh
        bunny login
        ```

        See [Installation](/docs/cli/installation) for npm and other options.
      </Step>

      <Step title="Create a site">
        From your project root, run:

        ```bash theme={null}
        bunny sites create my-site
        ```

        Replace `my-site` with a name for your site. The CLI creates a storage zone for your files and a pull zone to serve them, then links this directory to the new site. The site is served at a `b-cdn.net` address, and the CLI prints the URL.
      </Step>

      <Step title="Build and deploy">
        ```bash theme={null}
        bunny sites deploy --build
        ```

        The CLI runs the build command, uploads the output directory from the table above, and publishes it. Every deploy is kept, so you can roll back with `bunny sites deployments publish --previous`.
      </Step>

      <Step title="Deploy on every push (optional)">
        ```bash theme={null}
        bunny sites ci init
        ```

        This writes a GitHub Actions workflow to `.github/workflows/bunny-sites.yml` that deploys the site on every push to `main`. Add your API key to the repository as a `BUNNYNET_API_KEY` secret. The CLI offers to run `gh secret set BUNNYNET_API_KEY` for you.
      </Step>
    </Steps>
  </Tab>

  <Tab title="Manually">
    <Steps>
      <Step title="Build your site">
        From your project root, run <code>{build_0}</code>. The build writes your site to the output directory listed in the table above.
      </Step>

      <Step title="Create a storage zone">
        In the [bunny.net dashboard](https://dash.bunny.net), go to **Storage** and click **Add Storage Zone**. Give it a name, pick the main region closest to your audience, and click **Add Storage Zone**.
      </Step>

      <Step title="Upload your files">
        Open the storage zone's file manager and upload the contents of your output directory to the root of the zone. To script uploads, use the [Storage HTTP API](/docs/storage/http).
      </Step>

      <Step title="Create a pull zone">
        Go to **CDN** and click **Add Pull Zone**. Set **Origin Type** to **Storage Zone**, select the zone you created, and click **Add Pull Zone**.

        Your site is live at `https://<pull-zone-name>.b-cdn.net`.
      </Step>
    </Steps>
  </Tab>

## Add a custom domain

With the Bunny CLI, add the domain to your site:

```bash theme={null}
bunny sites domains add example.com
```

The CLI prints the `CNAME` record to create with your DNS provider. Once the record resolves, issue a free certificate with `bunny sites domains ssl example.com`.

For a manual deploy, add the hostname to your pull zone by following [Custom hostnames](/docs/cdn/custom-hostname).
