Javascript Socket Io Message Event Firing Multiple Times Stack Overflow

Javascript Socket Io Message Event Firing Multiple Times Stack Overflow Move the io.on( ) code outside of the route. you are re registering a new event handler every time the admin route is hit, thus you get multiple event handlers for the exact same events. res.render('admin'); dal.findallmessages(function(err, messages) { console.log('sent msgs'); socket.emit('getmsgs', messages); });. I am emitting an event for a specific client from the server but it is emitting twice and the socket.on () method is executing twice on the react.js frontend which is ruining my project.

Javascript Socket Io In Express Js On Connection Execute Multiple The message event is firing multiple times leading to a single message appearing multiple times on the recipient's box. i have routed the socket to exports.chat and was wondering if that is causing the problem? to narrow down the problem: the messages are firing the number of times = the sequence of connection of the client. Since socket.io v3, a new api inspired from the eventemitter2 library allows to declare catch all listeners. this feature is available on both the client and the server. adds a listener that will be fired when any event is emitted. acknowledgements are not caught in the catch all listener. I am facing an issue in my web meet project in which i used a simple peer library to create peer and socket.io library to share data. so the issue is that the last event is emitted from the server to a particular socket client. What essentially happening is, each time a new request arrives you are registering a event handler for message, hence it is fired as many times as the you have accessed chat url.

If you only want the socket.io event handlers to apply to specific admin clients, then you will need a different approach that uses some sort of authentication to decide whether a socket.io connection is allowed to connect or not. The message event is firing multiple times leading to a single message appearing multiple times on the recipient's box. i have routed the socket to exports.chat and was wondering if that is causing the problem?. When a socket.io event fires multiple times unexpectedly in your javascript application, it usually stems from how event listeners are registered or managed. socket.io handles events asynchronously and can cause events to fire multiple times if not handled correctly. When i click on send message button, then i fire an event and listen that event on server side and from server side i fire another event which i listen on frontend. i put my event listen code in componentdidmount. you can refer to below link to understand about the question more:.
