Is there any way to work with React in a Custom landing page?

plugins: [
    {
      async serverWillStart() {
        return {
          async renderLandingPage() {
            const html = `
<!DOCTYPE html>
<html>
  <head>
  </head>
  <body>
    <h1>Hello world!</h1>
  </body>
</html>`
;
            return { html };
          }
        }
      }
    }
  ]

I would like to integrate React here and start creating my custom landing page with React how can I do that? Thanks
