Dynamically Render Client Side with Next.js
Next.js has a handy feature for rendering a child component client side, instead of on the server.
Consider the following example, where you have a component in src/components/Analytics.js with a default export. 
import dynamic from "next/dynamic";
const DynamicAnalytics = dynamic(() => import("../components/Analytics"));
function Header(props) {
  return (
    <>
     <DynamicAnalytics />
     <OtherServerRenderedStuff {...props} />
    </>
  )
}
Named Exports
You can also use this dynamic importing feature with named exports. Consider the next example:
// src/components/Analytics.js
export function Analytics() {
  return (
    // ....
  )
}
import dynamic from "next/dynamic";
const DynamicAnalytics = dynamic(
  () => import("../components/Analytics").then(mod => mod.Analytics)
);
function Header(props) {
  return (
    <>
     <DynamicAnalytics />
     <OtherServerRenderedStuff {...props} />
    </>
  )
}
There are some gotcha's when using dynamic, so make sure to check out the docs and get familiar with the API.
