Next js - disable server side rendering on some pages

Question

Is it possible to disable ssr on some pages using Next js? For example, I have a page with a product description on which I use ssr for SEO but I also have a page with a list of items or products which I can filter and for that page, I don't want to use ssr because this page generates dynamically every time, how can I disable ssr on this page?

Answer 1

The dynamic() function can also be used without a dynamic import:

// components/NoSsr.jsx

import dynamic from 'next/dynamic'
import React from 'react'

const NoSsr = props => (
  <React.Fragment>{props.children}</React.Fragment>
)

export default dynamic(() => Promise.resolve(NoSsr), {
  ssr: false
})

Anything wrapped in this component will not be visible in the SSR source. For example:

// inside the page you want to disable SSR for

import NoSsr from "components/NoSsr";

Contact me at <NoSsr>email@example.com</NoSsr>

Answer 2

Lazy load the component and disable SSR: https://nextjs.org/docs/advanced-features/dynamic-import#with-no-ssr

import dynamic from 'next/dynamic'

const DynamicComponentWithNoSSR = dynamic(() => import('../components/List'), {
  ssr: false
})

export default () => <DynamicComponentWithNoSSR />

Answer 3

This will disable next.js SSR, put this on your _app.tsx

import type { AppProps } from "next/app";
import dynamic from "next/dynamic";
import React from "react";

const App = ({ Component, pageProps }: AppProps) => {
  return <Component {...pageProps} />;
};

export default dynamic(() => Promise.resolve(App), {
  ssr: false,
});

This is a late answer, but in case anyone runs into this:

const isServer = () => typeof window === `undefined`;

const Page = () => isServer() ? null : (

  <> 
      <YourClientSideComponent />
  </>
);

This is on the "page" level. isServer() prevents rendering of anything while on the server side. You could, if you wanted to, prevent ssr on the component level also:

const isServer = () => typeof window === `undefined`;

const Page = () =>(

  <> 
      { !isServer() && <YourClientSideComponent /> }
  </>
);

We can also use react-no-ssr React component.

Let's say Comments is our client only component. Now we need to render it only on the client. Here's how we do it.

import React from 'react';
import NoSSR from 'react-no-ssr';
import Comments from './comments.jsx';

const MyPage = () => (
  <div>
    <h2>My Blog Post</h2>
    <hr />
    <NoSSR>
      <Comments />
    </NoSSR>
  </div>
);

Here's a solution that i just came up with based on the something mentioned in the React docs: https://reactjs.org/docs/react-dom.html#hydrate

class ClientOnly extends React.Component {
  state = {
    isClient: false,
  };

  componentDidMount() {
    this.setState({
      isClient: true,
    });
  }

  render() {
    const { isClient } = this.state;
    const { children } = this.props;

    return isClient ? children : false;
  }
}

You can then wrap any component / block with this and it won't get rendered on the server. e.g.

<ClientOnly>You're logged in as {name}</ClientOnly>

This also prevents the following React.hydrate warning "Warning: Expected server HTML to contain a matching in ."

In @refactor answer, the react-no-ssr is not working for some typescript issue.

I just wrote a very simple NoSSR component as below:

import { ReactNode, useEffect, useLayoutEffect, useState } from 'react'

const DefaultOnSSR: React.FC = () => null

export const NoSSR: React.FC<{ children: ReactNode; onSSR?: ReactNode }> = ({ children, onSSR = <DefaultOnSSR /> }) => {
  const [onBrowser, setOnBrowser] = useState(false)
  useLayoutEffect(() => {
    setOnBrowser(true)
  }, [])
  return <>{onBrowser ? children : onSSR}</>
}

and can be used anywhere if you want to avoid SSR like below:

const MyPage = () => (
  <div>
    <h2>My Blog Post</h2>
    <hr />
    <NoSSR>
      <Comments />
    </NoSSR>
  </div>
);

Based entirly on the answer by Erik Hofer, you can create an HOC to wrap your pages or other components in.

import dynamic from 'next/dynamic';
import React from 'react';

const withNoSSR = (Component: React.FunctionComponent) => dynamic(
    () => Promise.resolve(Component),
    { ssr: false },
);

export default withNoSSR;

Then use as:

import React from 'react';
import withNoSSR from './withNoSSR';

function SomePage() {
    return (
        <div>Only renders in the browser</div>
    );
}

// wrap with HOC on export
export default withNoSSR(SomePage);

Another and I believe the simplest solution is to just use process.browser, which will only be true when ran on client side.

<div>
  {
    process.browser && <Hidden />
  }
</div>
