### Entry Point
When running `nuxt build` with the Node server preset, the result will be an entry point that launches a ready-to-run Node server.
```bash
node .output/server/index.mjs
```
### Example
```bash
$ node .output/server/index.mjs
Listening on http://localhost:3000
```
### Configuring Defaults at Runtime
This preset will respect the following runtime environment variables:
-`NITRO_PORT` or `PORT` (defaults to `3000`)
-`NITRO_HOST` or `HOST` (defaults to `'0.0.0.0'`)
-`NITRO_SSL_CERT` and `NITRO_SSL_KEY` - if both are present, this will launch the server in HTTPS mode. In the vast majority of cases, this should not be used other than for testing, and the Nitro server should be run behind a reverse proxy like nginx or Cloudflare which terminates SSL.
You can use `NITRO_PRESET=node_cluster` in order to leverage multi-process performance using Node.js [cluster](https://nodejs.org/dist/latest/docs/api/cluster.html) module.
By default, the workload gets distributed to the workers with the round robin strategy.

## Static Hosting
There are two ways to deploy a Nuxt application to any static hosting services:
- Static site generation (SSG) with `ssr: true` pre-renders routes of your application at build time. (This is the default behaviour when running `nuxi generate`.) It will also generate `/200.html` and `/404.html` single-page app fallback pages, which can render dynamic routes or 404 errors on the client (though you may need to configure this on your static host).
- Alternatively, you can prerender your site with `ssr: false` (static single-page app). This will produce HTML pages with an empty `<div id="__nuxt"></div>` where your Vue app would normally be rendered. You will lose many of the benefits of prerendering your site, so it is suggested instead to use `<ClientOnly>` to wrap the portions of your site that cannot be server rendered (if any).
Use the [`nuxi generate` command](/docs/api/commands/generate) to build your application. For every page, Nuxt uses a crawler to generate a corresponding HTML and payload files. The built files will be generated in the `.output/public` directory.
If you don't want to pre-render your routes, another way of using static hosting is to set the `ssr` property to `false` in the `nuxt.config` file. The `nuxi generate` command will then output an `.output/public/index.html` entrypoint and JavaScript bundles like a classic client-side Vue.js application.
```ts [nuxt.config.ts|js]
defineNuxtConfig({
ssr: false
})
```
## Presets
In addition to Node.js servers and static hosting services, a Nuxt 3 project can be deployed with several well-tested presets and minimal amount of configuration.
