mountId

  • Type: string
  • Default: 'root'

By default, the root element is included in the HTML template for component mounting, and the element id can be modified through mountId.

<body>
  <div id="root"></div>
</body>

Example

Set the id to app:

export default {
  html: {
    mountId: 'app',
  },
};

After compilation:

<body>
  <div id="app"></div>
</body>

Notes

Update Relevant Code

After modifying mountId, if there is logic in your code to obtain the root root node, please update the corresponding value:

- const domNode = document.getElementById('root');
+ const domNode = document.getElementById('app');

ReactDOM.createRoot(domNode).render(<App />);

Custom Templates

If you customized the HTML template, please make sure that the template contains <div id="<%= mountId %>"></div>, otherwise the mountId config will not take effect.
