server.addService(/* ... */);

// add interceptor
server.use(async (context, next) => {
  // preprocess
  const start = Date.now();
  try {
    await next();
  } finally {
    // postprocess
    const costtime = Date.now() - start;
    console.log('costtime is', costtime);
    console.log('unary response is ', context.response);
  }
});

serer.bind(/* ... */);
server.start();

gRPC has 4 kinds of call:

Context

• call current gRPC call
• definition the method definition of current call
• response response if response is not stream
• onFinished(...) you can listen on call finish event, no matter response of current call is stream or not. So you don't need to care about what kind is the call. It is very useful to do something like tracing, logging

Notes

• await next() would wait the call to be finished if response is not stream.
