Stream.write()

Caution

Starting on k6 v0.49, the experimental module k6/experimental/grpc has been graduated, and its functionality is now available in the k6/net/grpc module. The k6/experimental/grpc is deprecated and will be removed in v0.51.0.

To migrate your scripts, replace all k6/experimental/grpc imports with k6/net/grpc.

Writes a message to the stream.

Example

JavaScript 
import { Client, Stream } from 'k6/experimental/grpc';
import { sleep } from 'k6';

const COORD_FACTOR = 1e7;

const client = new Client();
client.load([], '../../grpc_server/route_guide.proto');

export default () => {
  if (__ITER == 0) {
    client.connect('127.0.0.1:10000', { plaintext: true });
  }

  const stream = new Stream(client, 'main.RouteGuide/RecordRoute');

  stream.on('data', (stats) => {
    console.log('Finished trip with', stats.pointCount, 'points');
  });

  // send an item
  stream.write({ latitude: 406109563, longitude: -742186778 });

  // send end-signal to the server
  stream.end();

  sleep(1);
};
