      The rs preview command uses Rsbuild to preview an application's production build locally.

      Usage

      rs preview [options]

      The command loads the application configuration registered with define.app(). Run rs build before starting the preview server to generate the production output:

      rs build
rs preview

      rs preview is intended for local preview only. Do not use it as a production server.

      Options

      rs preview supports the same preview server options as Rsbuild. See the Rsbuild CLI documentation for details.

      Examples:

      # Start the preview server and open the page in the browser
rs preview --open

# Use port 8080 and fail if it is already in use
rs preview --port 8080 --strict-port

# Make the preview server available on the local network
rs preview --host

      Configuration

      Configure the preview server through define.app() in the Rstack configuration file. It accepts the standard Rsbuild configuration:

      rstack.config.ts
      import { define } from 'rstack';

define.app({
  server: {
    open: true,
    port: 8080,
  },
});
