Suspense

info

• Ensure you're on the latest version of React
• If you use suspense with tRPC's automatic SSR in Next.js, the full page will crash on the server if a query fails, even if you have an <ErrorBoundary />

Usage

tip

useSuspenseQuery & useSuspenseInfiniteQuery both return a [data, query]-tuple, to make it easy to directly use your data and renaming the variable to something descriptive

useSuspenseQuery()

tsx
// @filename: pages/index.tsx
import React from 'react';
import { trpc } from '../utils/trpc';
 
function PostView() {
  const [post, postQuery] = trpc.post.byId.useSuspenseQuery({ id: '1' });
          
const post: {
    id: string;
    title: string;
}
 
  return <>{/* ... */}</>;
}

tsx
// @filename: pages/index.tsx
import React from 'react';
import { trpc } from '../utils/trpc';
 
function PostView() {
  const [post, postQuery] = trpc.post.byId.useSuspenseQuery({ id: '1' });
          
const post: {
    id: string;
    title: string;
}
 
  return <>{/* ... */}</>;
}

useSuspenseInfiniteQuery()

tsx
// @filename: pages/index.tsx
import React from 'react';
import { trpc } from '../utils/trpc';
function PostView() {
  const [pages, allPostsQuery] = trpc.post.all.useSuspenseInfiniteQuery(
    {},
    {
      getNextPageParam(lastPage) {
        return lastPage.nextCursor;
      },
    },
  );
  const { isFetching, isFetchingNextPage, fetchNextPage, hasNextPage } =
    allPostsQuery;
  return <>{/* ... */}</>;
}

tsx
// @filename: pages/index.tsx
import React from 'react';
import { trpc } from '../utils/trpc';
function PostView() {
  const [pages, allPostsQuery] = trpc.post.all.useSuspenseInfiniteQuery(
    {},
    {
      getNextPageParam(lastPage) {
        return lastPage.nextCursor;
      },
    },
  );
  const { isFetching, isFetchingNextPage, fetchNextPage, hasNextPage } =
    allPostsQuery;
  return <>{/* ... */}</>;
}

useSuspenseQueries()

Suspense equivalent of useQueries().

tsx
const Component = (props: { postIds: string[] }) => {
  const [posts, postQueries] = trpc.useSuspenseQueries((t) =>
    props.postIds.map((id) => t.post.byId({ id })),
  );
  return <>{/* [...] */}</>;
};

tsx
const Component = (props: { postIds: string[] }) => {
  const [posts, postQueries] = trpc.useSuspenseQueries((t) =>
    props.postIds.map((id) => t.post.byId({ id })),
  );
  return <>{/* [...] */}</>;
};
