Question

This, you mean? From the npm package's readme: io.on('connection', socket =>

{
socket.emit('request', /* … */); // emit an event to the socket
io.emit('broadcast', /* … */); // emit an event to all connected sockets
socket.on('reply', () => { /* … */ }); // listen to the event
});

I have 10 messages on server which I fetch from DB. Now i want to send message one by one. Lets say if I send 1st msg then I want to send second message only when we get response for 1st message. If we dont get response to 1st message then dont send second message. How will server know response is received for first message? How to keep track of that

A loop

loop does not work in case of socket messaging I read few blogs and they have mentioned there will be some deplay in messaging if we loop over individual messages. I have one more idea should I send entire data i.e 10 messages to client and then this looping logic will get handled on client side so I will send bulk data via socket i.e 10 messages in this case

You can do bulking if that works for you, it would probably even be faster

By bulk I mean to say I have array of 10 messages with each message is object with some info so I will be sending entire array from server to client instead of sending single object one by one. Just wanted to know will this cause any performance issue? If I send data in bulk? Is there any limit on payload size?

No limits if you use highlevel libraries like socket.io

I have one use case in which I have some data in array and each array element I want to send to client one by one. So when first element is send via websocket I want to send second element from array only when we get response for first element from client and this should happen for all the array elements. How can this be done in websockets any suggestions or pointers?
