It is a highly performant and reliable library optimized to process a large volume of data messages with minimal delay. Socket.io is a popular JavaScript library that allows us to create real-time, bi-directional communication between clients and a Node.js server. Node.js has a built-in WebSocket module, but this module doesn’t provide the functionalities required to build complex real-time applications this is why Socket.io exists. We bring you the whole solution without dealing with WebSockets / scaling / databases / servers. If you are looking to implement in-app notifications (kind of like Facebook / Instagram / Upwork etc.), Check out Novu. Compared to HTTP, WebSockets provide a lasting bi-directional client-server connection, making it possible for data to change in real-time without refreshing the page. WebSockets create a connection between a client and a server, allowing them to send data both ways client-server and server-client. Have you ever used a forex trading app or visited a sports betting website? You will notice that the data changes almost every minute these changes are possible with the help of WebSockets. This type of communication is an HTTP connection, suitable for applications where data doesn’t change frequently.
The browser displays the response as web pages to the user.The server receives the request and sends an HTTP response containing the related files to the web browser.The browser sends a request to the web server, asking for resources related to the URL.A user provides a URL to the web browser.Router.get('/', function(req, res, next) ]
routes folder var express = require('express') This is my app.js const express = require('express') Ĭonst server = require('http').createServer(app) Ĭonst io = require('socket.io').listen(server) Īnd route file api.js in. Use socket.io in expressjs routes instead of in main server.js file How use socket.io in express routes with node.js May be because of my lack of understanding of express routes. I found many similar questions and tried to implement the solution as suggested but nothing worked out. In one of my node.js script i am trying to use socket.io in express route.
