How do I add a client route?

[agamm]

I want to have a few pages generated statically and a route at /app which is a client-side react app (no need for SEO).
In Gatsby there is gatsby-plugin-create-client-paths

Is there an equivilant / a solution?
Bonus points if there isn't any noticable page reload

Using a Link component from next/link. Ref : https://nextjs.org/docs/api-reference/next/link

@VivekNeel what do you mean? I already am using it but how can I connect it to a react app ?

 <p className="description">
          <Link href="/clientside"><a>Client side app (react)!</a></Link>
  </p>

pages/clientside is basically a create-react-app I have (client side app, no need to statically generate).
