      copyOnBuild?: boolean;
      watch?: boolean;
    };

Options#

name#

• Type: string
• Default: 'public'

The name of the public directory. The value of name can be set to a relative path or an absolute path. Relative path will be resolved relative to the project root directory.

• Relative path example:

export default {
  server: {
    publicDir: {
      name: '../some-public',
    },
  },
};

• Absolute path example:

import path from 'node:path';

export default {
  server: {
    publicDir: {
      name: path.join(__dirname, '../some-public'),
    },
  },
};

copyOnBuild#

• Type: boolean
• Default: true

Whether to copy files from the publicDir to the distDir on production build.

For example, disable copyOnBuild:

export default {
  server: {
    publicDir: {
      copyOnBuild: false,
    },
  },
};

Note that setting the value of copyOnBuild to false means that when you run rsbuild preview for a production preview, you will not be able to access the corresponding static resources.

watch#

• Type: boolean
• Default: false

Whether to watch the public directory and reload the page when the files change.

Setting watch to true allows the development environment to watch changes to files in the specified public directory and reload the page when the files are changed:

export default {
  server: {
    publicDir: {
      watch: true,
    },
  },
};

Note that the watch option is only valid in the development build. If dev.hmr and dev.liveReload are both set to false, watch will be ignored.

Disabled#

You can set publicDir to false to disable the static assets serving:

export default {
  server: {
    publicDir: false,
  },
};
