Cancellation example usage:

• deadline (see tests/signalInterceptor.test.ts)

const deadline = new Date();
deadline.setMilliseconds(deadline.getMilliseconds() + 1000); // timeout 1000 ms
md["deadline"] = deadline.getTime().toString();

• cancellation (streaming)

const options = {
  streamInterceptors: [new SignalStreamInterceptor()],
};
const client = new EchoServiceClient("", null, options);
const req = new ServerStreamingEchoRequest();
const controller = new AbortController(); // controller usually created by frameworks e.g. redux-toolkit
const stream = client.serverStreamingEcho(req, { signal: controller.signal, } as MetadataWithSignal);
controller.abort();

N.B.

• StreamInterceptor works with RPC client
• createPromiseClient doesn't work for cancellation, see tests/promiseClient.test.ts skipped test
