Top Socket.IO Coders, Programmers for Hire in Ukraine

Socket.IO is a JavaScript networking library for real-time web applications, which enables real-time bidirectional event-based communication between servers and clients. It has two parts: a client-side library that runs in the browser, and a server-side library for Node.js. Both components have a nearly identical API. Like Node.js, it is event-driven. It also includes convenient features such as broadcasting to multiple sockets, multicasts, storing data associated with each client. It is used for developing the real-time application like chat messenger, online games etc. The key features of Socket.IO are the auto-reconnection support which means that a disconnected client will try to reconnect until the server is available again, disconnection detection which allows both the server and the client get to know when the other one is not responding anymore, and reliability. It provides an opportunity to implement real-time analytics, binary streaming, collaboration with documents, and instant messaging. Socket.IO works on any platform, a browser or device, equally oriented to reliability and speed.

Is using Socket.IO with React JS a good idea?

“I’ve been using Socket.IO in a big production application and it’s been great, specially when you take advantage of the real-time updates. First we created a simple integration with browser events but now we are refactoring to have a better handler. This is done by using high order component that wraps any component that actually needs socket data. This allows us to decouple all the socket logic and have it in one single place…”

What is the difference between Redis Pub/Sub and Socket.IO?

“Redis is a server and Socket.IO is a library. Socket.IO manages the connection to a browser or an app from node.js, using web sockets and other fallback technologies. Redis is a generic pub/sub server that emits events that you can subscribe to and use as part of your application. The two actually work together. Because node.js is single threaded, there’s a limit to how many sockets it can hold open (a large limit, but still a limit). So to have multiple socket servers work together, especially for broadcasting events to users, there’s a Socket.IO adapter called socket.io-redis…”
