ness start
Serves an existing production build using the Ness Node runtime.
ness start [options]
| Option | Description | Default |
|---|---|---|
--host <host> | Server hostname | 0.0.0.0 |
--port <port> | Server port | 3000 |
--build <file> | Server build entry | build/server/index.js |
ness build
ness start --host 127.0.0.1 --port 8080
When flags are omitted, HOST and PORT environment variables override the listed defaults, which makes the command work with managed hosting platforms without wrapper scripts.
The production runtime serves immutable assets, public files, SSR and RSC responses, routing rules, middleware, page caching, image optimization, and the Ness health endpoint. The command fails early when the selected server build does not exist.
