Aborting Procedure Calls - Trpc

tRPC adheres to the industry standard when it comes to aborting procedures. All you have to do is pass an AbortSignal to the query or mutation options, and call the AbortController instance's abort method if you need to cancel the request.

// @target: esnext
// ---cut---
// @filename: server.ts
import { createTRPCProxyClient, httpBatchLink } from '@trpc/client';
// @noErrors
import type { AppRouter } from 'server.ts';

const proxy = createTRPCProxyClient<AppRouter>({
  links: [
    httpBatchLink({
      url: 'http://localhost:3000/trpc',
    }),
  ],
});

// 1. Create an AbortController instance - this is a standard javascript API
const ac = new AbortController();

// 2. Pass the signal to a query or mutation
const query = proxy.userById.query('id_bilbo', { signal: ac.signal });

// 3. Cancel the request if needed
ac.abort();
