Core Concepts

# Zero Runtime

[Copy for LLMs](https://nuxtseo.com/docs/sitemap/guides/zero-runtime.md)

If your sitemap URLs only change when you deploy, you don't need to ship sitemap generation code to production. The `zeroRuntime` option generates sitemaps at build time and tree-shakes the generation code from your server bundle.

## [Usage](#usage)

To enable zero runtime, add the following to your config:

nuxt.config.ts

```
export default defineNuxtConfig({
  sitemap: {
    zeroRuntime: true
  }
})
```

When enabled, the module will automatically add `/sitemap.xml` to your prerender routes. The sitemap will be generated during build and served as a static file at runtime.

## [How it Works](#how-it-works)

With `zeroRuntime: true`:

1. Sitemap routes are automatically added to `nitro.prerender.routes`
2. Server handlers use dynamic imports gated by `import.meta.prerender`
3. At build time, the sitemap generation code is tree-shaken from the runtime bundle
4. Static XML files are served directly without any sitemap code execution

## [Development Mode](#development-mode)

Zero runtime mode still works in development (`nuxt dev`). The sitemap generation code runs normally during development so you can test your configuration.

## [Benchmarks](#benchmarks)

Enabling `zeroRuntime` reduces the server bundle by approximately:

- **~50KB** uncompressed
- **~5KB** gzip

This is the sitemap generation code (XML building, URL normalization, source fetching) being tree-shaken from the bundle.

## [Limitations](#limitations)

- Runtime sitemap generation is not available - sitemaps are only generated during build
- Dynamic data sources that require runtime fetching won't work
- Debug endpoints are disabled in zero runtime mode

## [When to Use](#when-to-use)

Zero runtime is ideal when:

- Your pages only change when you commit and deploy
- You're using `nuxt generate` for a fully static site
- You want to minimize your server bundle size for edge/serverless

## [When Not to Use](#when-not-to-use)

Avoid zero runtime when:

- Your CMS updates content without redeploying
- You have user-generated content that changes frequently
- Your sitemap URLs depend on runtime data
