Socket.io is a library that abstracts real-time communication and allows for building a chat application. It supports multiple transport mechanisms like websockets, long polling, and JSONP polling to work across browsers. Socket.io works with Node.js on the server and supports communication with clients across various browsers and devices. It also integrates with technologies like Redis and PostgreSQL.
