#html.title

• Type: string ｜ Function
• Default: 'Rsbuild App'

Set the title tag of the HTML page.

#String usage

html.title can be directly set as a string:

export default {
  html: {
    title: 'Example',
  },
};

The title tag generated in HTML will be:

<title>Example</title>

#Function usage

• Type:

type TitleFunction = ({ value: string; entryName: string }) => string | void;

When html.title is of type Function, the function receives an object as the argument, and the object's values include:

• value: the default title configuration of Rsbuild.
• entryName: the name of the current entry.

In the MPA (multi-page application) scenario, you can return different title strings based on the entry name, thus generating different title tags for each page:

export default {
  html: {
    title({ entryName }) {
      const titles = {
        foo: 'Foo Page',
        bar: 'Bar Page',
      };
      return titles[entryName] || 'Other Page';
    },
  },
};

#Unset <title> tag

When html.title is set to an empty string, Rsbuild will not inject the <title> tag:

export default {
  html: {
    title: '',
  },
};
