Sending message to specific user with socket.io, Instead, we were broadcasting the messages and showing to the specific user that by AngularJs. But this article is truly based on Sending We can send the message to all the connected clients, to clients on a namespace and clients in a particular room. To broadcast an event to all the clients, we can use the io.sockets.emit method. Note − This will emit the event to ALL the connected clients (event the socket that might have fired this event). In this example, we will broadcast the number of connected clients to all the users.

Socket.io client not receiving messages from server

Socket io emit to room

Emit cheatsheet, emit() are the main two emit methods we use in Socket. io's Rooms (https://github.com/LearnBoost/socket.io/wiki/Rooms) Rooms allow simple partitioning of the connected clients. This allows events to be emitted with to subsets of the connected client list, and gives a simple method of managing them. You can emit to several rooms at the same time: io.to ('room1').to ('room2').to ('room3').emit ('some event'); In that case, an union is performed: every socket that is at least in one of the rooms will get the event once (even if the socket is in two or more rooms). You can also broadcast to a room from a given socket:

Socket.io rooms difference between broadcast.to and sockets.in , socket.broadcast.to('game').emit('message', 'nice game');. // sending to all clients in 'game' room(channel), include sender. io.in('game').emit('message', 'cool In socket.io, you usually use a specific syntax on the server side if you want to send a message to a specific room: io.to(room).emit('event', 'message');. But how would a client (what I mean is the socket.io-related code running in a browser) indicate that a message should go to a specific room?

More Articles

In this article we’ll be exploring the basic of setting up a realtime chat app using Socket.IO.

Exfat or fat32 for mac. Since, for the sake of simplicity, we won’t be including any backend storage for our messages. Previously sent messages just won’t be visible by any new pages, to make it so that there’s no saved data to load in, but to learn more about setting up a simple backend for your data using Mongoose and the MongoDB Atlas database, you can check out my article here

Prerequisites

All we need is a basic understanding of Express, to set up the server, which we have another article on, and the official docs are always helpful too.

Socket Io Emit Cheat Sheet

Installation

File Setup

Here’s the file layout for our simple project

Let’s setup our messenger, to avoid needing another file for styling, I’ll be using the Tailwind CSS framework.

All we need are our imports from Tailwind, the socket.IO front-end client (different from what we installed using npm), an empty div to render our new messages into, and a simple form for the user’s name and message.

index.html

We’re going to keep it simple here, for now. We just need to initialize Socket.IO on the client-side using the io() function.

chat.js

Bam, that’s it for now. Chat.js will be very useful later for moving data between the front and back-end of our site.

After we’ve set up a basic Express server we need to import the path and http Node modules. We’ll convert our normal server into a more useful form for Socket.IO, and make a new server with that. We’ll then start the server on port 3000 using app.use.

server.js

Try opening a new page on localhost:3000, whenever there’s a new tab or a reload, the “new connection” message should appear in the terminal.

Socket Io Emit To Room

Basic Functions

There are only a few basic functions that we’ll need for our example:

Socket Io Emit

• emit() Takes the event you want called and what you want to send with it, like a message.
• on() Takes an event name and a callback function with what do do when the event is triggered. Takes the connection and disconnect events by default but you can add custom events.
• broadcast.emit() Sends to every user but the sender.

Sending and Rendering Messages

Basically, when we get the sendMessage event from chat.js we emit a new event to the client to render the new message. So, while only one client called the event, all users on the server will get the message.

With broadcast be can log whenever someone has joined the server to everyone but the new user.

server.js

Client-side

In here we’ll set our io instance to a more useful variable. We’re also going to setup and emit when we submit the form, sending an object with our data to server.js which is then sent back to all clients on the ‘showMessage’ event. With that all we need to do is render it to the screen:

chat.js

Now if you open localhost:3000 on two different tabs and send a message, they should be instantaneously rendered on both.

Conclusion

With relatively little code we can make a basic messaging system without needing to send and wait for data. If something didn’t work for you you can look at my live example and check out the code on Github.
