Socket Io Check If Room Exists

I have to check for now if my rooms are empty which is an hassle because io adapter rooms is an array of json meaning you have to count properties.

Socket io check if room exists.

Each socket in socket io is identified by a random unguessable unique identifier socket id for your convenience each socket automatically joins a room identified by its own id. A javascript library for real time web applications that enables real time bi directional communication between web clients and servers. When a client joins a room either the room exists or it has to be created. To leave a channel you call leave in the same fashion as join both methods are asynchronous and accept a callback argument.

A client side library that runs in the browser and a server side library for node js. In this article i ll be showing you how to build a web chat application using react express socket io and node js. Have to follow the below mentioned steps on the server side. With socket io 1 2 0 my empty rooms do get deleted automatically.

Ncacace i think your use case is a bit too specific to be implemented in socket io internals. In socket io 2 every user socket create room with the name as the socket id. Socket io enables real time bidirectional and event based communication. Socket io is a real time application framework based on node js which has a wide range of applications including instant messaging notification and message push real time analysis and other scenarios.

It works on every platform browser or device focusing equally on reliability and speed. If there is no user inside the room the room or the user doesn t exist and the user is not connected. What i do is to get the room based on the id of the socket i get all the clients inside the room and check if there is an user inside the room. Push data to clients that gets represented as real time counters charts or logs.

Socket io has two components. Both components have nearly identical apis. No change on the client side. The room is destroyed once.

The room can be specified by a specific chat id or a meeting id. What type of database is the best for storing array or object like data on hold database node js sockets. In that case every socket in the room excluding the sender will get the event.
