@apollo/client-integration-tanstack-start

This package provides integrations between Apollo Client and TanStack Start to support modern streaming SSR.

Setup

Install dependencies:

npm i @apollo/client-integration-tanstack-start @apollo/client graphql

In your routes/__root.tsx, change from createRootRoute to createRootRouteWithContext to provide the right context type to your application.

+import type { ApolloClientIntegration } from "@apollo/client-integration-tanstack-start";
import {
-   createRootRoute
+   createRootRouteWithContext
} from "@tanstack/react-router";

-export const Route = createRootRoute({
+export const Route = createRootRouteWithContext<ApolloClientIntegration.RouterContext>()({

In your router.tsx, set up your Apollo Client instance and run routerWithApolloClient

import {
  routerWithApolloClient,
  ApolloClient,
  InMemoryCache,
} from "@apollo/client-integration-tanstack-start";
import { HttpLink } from "@apollo/client";
import { createRouter } from "@tanstack/react-router";
import { routeTree } from "./routeTree.gen";

export function getRouter() {
  const apolloClient = new ApolloClient({
    cache: new InMemoryCache(),
    link: new HttpLink({ uri: "https://your.graphql.api" }),
  });
  const router = createTanStackRouter({
    routeTree,
    context: {
      ...routerWithApolloClient.defaultContext,
    },
  });

  return routerWithApolloClient(router, apolloClient);
}

[!IMPORTANT]
ApolloClient and InMemoryCache need to be imported from @apollo/client-integration-tanstack-start, not from @apollo/client.

Usage

loader with preloadQuery and useReadQuery

import { useReadQuery } from "@apollo/client";
import { createFileRoute } from "@tanstack/react-router";

export const Route = createFileRoute("/loader-defer")({
  component: RouteComponent,
  loader: ({ context: { preloadQuery } }) => {
    const queryRef = preloadQuery(QUERY, {
      variables: { myVariable: "myValue" },
    });
    return {
      queryRef,
    };
  },
});

function RouteComponent() {
  const { queryRef } = Route.useLoaderData();
  const { data } = useReadQuery(queryRef);

  return (
    <div> do something with `data` here </div>
  )
}

useSuspenseQuery

You can also use the suspenseful Apollo Client api useSuspenseQuery (or useQueryRef and useReadQuery) directly into your component without a loader:

import { useSuspenseQuery } from "@apollo/client";
import { createFileRoute } from "@tanstack/react-router";

export const Route = createFileRoute("/myPage")({
  component: RouteComponent,
});

function RouteComponent() {
  const { data } = useSuspenseQuery(QUERY);

  return <div> do something with `data` here </div>;
}
