Examples

JavaScript
import grpc from 'k6/net/grpc';

const client = new grpc.Client();
// Download addsvc.proto for https://grpcbin.test.k6.io/, located at:
// https://raw.githubusercontent.com/moul/pb/master/addsvc/addsvc.proto
// and put it in the same folder as this script.
client.load(null, 'addsvc.proto');

export default () => {
  client.connect('grpcbin.test.k6.io:9001', { timeout: '5s' });

  const response = client.invoke('addsvc.Add/Sum', {
    a: 1,
    b: 2,
  });
  console.log(response.message.v); // should print 3

  client.close();
};
JavaScript
import grpc from 'k6/net/grpc';

  const resp = client.invoke('google.cloud.authorization.v1.AuthService/GetAccessToken', {
    username: 'john.smith@k6.io',
    password: 'its-a-secret',
