export default () => {
if (__ITER == 0) {
client.connect('127.0.0.1:10000', { plaintext: true });
}
const stream = new Stream(client, 'main.RouteGuide/RecordRoute');
// sets up a handler for the data (server sends data) event
stream.on('data', (stats, metadata) => {
console.log('It took', stats.elapsedTime, 'seconds');
console.log('This message has been received:', metadata.ts);
});
stream.on('end', function () {
// The server has finished sending
client.close();
});
