So on the 1st call, while connection is in progress, any subsequent client
calls made are stacked up. once the connection is established the call
stack is resolved.
Just to validate: I made 3 calls after a 1st init call gets resolved as in
code below. Prints in the order of 1,2,3
Thanks for your reply.
client.sayHello({name: "init"}, function(err, response) {
console.log('init complete', response.message);
client.sayHello({name: "1"}, function(err, response) {
console.log('1 Sayhello:', response.message);
});
client.sayHello({name: "2"}, function(err, response) {
console.log('2 Sayhello:', response.message);
});
client.sayHello({name: "3"}, function(err, response) {
console.log('3 Sayhello:', response.message);
});
});
