For standalone mode the server handles file servering in addition to the page and API routes.
#### Custom host and port
You can override the host and port the standalone server runs on by passing them as environment variables at runtime:
```shell
HOST=0.0.0.0 PORT=3000 node ./dist/server/entry.mjs
```
#### HTTPS
By default the standalone server uses HTTP. This works well if you have a proxy server in front of it that does HTTPS. If you need the standalone server to run HTTPS itself you need to provide your SSL key and certificate.
