Convenient state management of query parameters in Next.js apps.

Persisting React state to query parameters is often a good idea:

When the URL is shared, the app state is restored. Same applies to bookmarks.
When using the browser back button, the state of the previous page is restored.
When navigating forward to a page the user was already on, the state is reset.

This library is an adapter for use-query-params to integrate with Next.js.

Installation

npm install next-query-params use-query-params

App Router

// app/layout.tsx

'use client';

import NextAdapterApp from 'next-query-params/app';
import {QueryParamProvider} from 'use-query-params';

export default function RootLayout({children}) {
  return (
    <html lang="en">
      <body>
        <QueryParamProvider adapter={NextAdapterApp}>
          {children}
        </QueryParamProvider>
      </body>
    </html>
  );
}

Pages Router

// _app.tsx
import NextAdapterPages from 'next-query-params/pages';
import {QueryParamProvider} from 'use-query-params';

export default function App({Component, pageProps}) {
  return (
    <QueryParamProvider adapter={NextAdapterPages}>
      <Component {...pageProps} />
    </QueryParamProvider>
  );
}

Usage

Please refer to the usage of use-query-params.

import {useQueryParam, StringParam, withDefault} from 'use-query-params';

export default function IndexPage() {
  const [name, setName] = useQueryParam('name', withDefault(StringParam, ''));

  function onNameInputChange(event) {
    setName(event.target.value);
  }

  return (
    <p>My name is <input value={name} onChange={onNameInputChange} /></p>
  );
}

Shallow routing (Pages Router-only)

NextAdapter can be configured to opt-out of shallow routing. In this case server-side functions like getServerSideProps will be run again when a query parameter changes.

// _app.tsx
import NextAdapterPages from 'next-query-params/pages';
import {QueryParamProvider} from 'use-query-params';

function Adapter(props) {
  return <NextAdapter {...props} shallow={false} />;
}

export default function App({Component, pageProps}) {
  return (
    <QueryParamProvider adapter={Adapter}>
      <Component {...pageProps} />
    </QueryParamProvider>
  );
}
