中止过程调用

默认情况下，tRPC 不会取消卸载请求。如果你想选择此行为，可以在配置回调中提供 abortOnUnmount。

¥By default, tRPC does not cancel requests on unmount. If you want to opt into this behavior, you can provide abortOnUnmount in your configuration callback.

全局地

¥Globally

client.ts
ts
// @filename: utils.ts
import { createTRPCNext } from '@trpc/next';
 
export const trpc = createTRPCNext<AppRouter>({
  config() {
    return {
      // ...
      abortOnUnmount: true,
    };
  },
});

client.ts
ts
// @filename: utils.ts
import { createTRPCNext } from '@trpc/next';
 
export const trpc = createTRPCNext<AppRouter>({
  config() {
    return {
      // ...
      abortOnUnmount: true,
    };
  },
});

预请求

¥Per-request

你还可以在请求级别覆盖此行为。

¥You may also override this behavior at the request level.

client.ts
ts
// @filename: pages/posts/[id].tsx
import { trpc } from '~/utils/trpc';
 
const PostViewPage: NextPageWithLayout = () => {
  const id = useRouter().query.id as string;
  const postQuery = trpc.post.byId.useQuery({ id }, { trpc: { abortOnUnmount: true } });
 
  return (...)
}

client.ts
ts
// @filename: pages/posts/[id].tsx
import { trpc } from '~/utils/trpc';
 
const PostViewPage: NextPageWithLayout = () => {
  const id = useRouter().query.id as string;
  const postQuery = trpc.post.byId.useQuery({ id }, { trpc: { abortOnUnmount: true } });
 
  return (...)
}
