@react-libraries/next-exchange-ssr

SSR with urql in Next.js and Remix. Does not require 'withUrqlClient'.

Sample

src/pages/_app.tsx

import { useMemo, useState } from "react";
import { cacheExchange, Client, fetchExchange, Provider } from "urql";
import {
  useCreateNextSSRExchange,
  NextSSRProvider,
  NextSSRWait,
} from "@react-libraries/next-exchange-ssr";
import type { AppType } from "next/app";

const isServerSide = typeof window === "undefined";
const endpoint = "/api/graphql";
const url = isServerSide
  ? `${
      process.env.VERCEL_URL
        ? `https://${process.env.VERCEL_URL}`
        : "http://localhost:3000"
    }${endpoint}`
  : endpoint;

const App: AppType = ({ Component, pageProps }) => {
  // NextSSRExchange to be unique on AppTree
  const nextSSRExchange = useCreateNextSSRExchange();
  const client = useMemo(() => {
    return new Client({
      url,
      // Only on the Server side do 'throw promise'.
      suspense: isServerSide,
      exchanges: [cacheExchange, nextSSRExchange, fetchExchange],
    });
  }, [nextSSRExchange]);

  return (
    <Provider value={client}>
      {/* Additional data collection functions for SSR */}
      <NextSSRProvider>
        <Component {...pageProps} />
        <NextSSRWait>
          {/* Describe components to be called after the end of asynchronous processing. */}
        </NextSSRWait>
      </NextSSRProvider>
    </Provider>
  );
};

// Create getInitialProps that do nothing to prevent Next.js optimisation.
App.getInitialProps = () => ({});

export default App;

src/pages/index.tsx

import { gql, useQuery } from "urql";

// Date retrieval
const QUERY = gql`
  query date {
    date
  }
`;

const Page = () => {
  const [{ data }, refetch] = useQuery({ query: QUERY });

  return (
    <>
      <a
        target="_blank"
        href="https://github.com/SoraKumo001/next-urql"
        rel="noreferrer"
      >
        Source code
      </a>
      <hr />
      {/* SSRedacted data can be updated by refetch. */}
      <button onClick={() => refetch({ requestPolicy: "network-only" })}>
        Update date
      </button> {/* Dates are output as SSR. */}
      {data?.date &&
        new Date(data.date).toLocaleString("en-US", { timeZone: "UTC" })}
    </>
  );
};

export default Page;
