## 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.

### Using PM2

To use `pm2`, use an `ecosystem.config.js`:

```js [ecosystem.config.js]
module.exports = {
  apps: [
    {
      name: 'NuxtAppName',
      exec_mode: 'cluster',
      instances: 'max',
      script: './.output/server/index.mjs'
    }
  ]
}
```
