This bidirectional communication can run on every platform, device, or browser, and its main focus is speed and reliability. The development of real-time applications using old languages or PHP is really hard, as it requires a lot of changes and different functionalities to be taken care of. All this slows the development time – something that can be avoided with Socket.IO.
What are the main features and applications of Socket.IO
Socket.IO provides great reliability in terms of communication. This is very important because having a reliable service when you have communication between two ends is a must. Also, the connection is established in the presence of both load balancers and proxies, and anti-viruses and personal firewall.
It also allows the developer to create two implementations – Namespaces and Rooms. Namespaces offer the ability for the creation of socket connections with different paths or endpoints, which turns up with minimizations of resources.
Another advanced feature of Socket.IO is the auto-reconnect service – in case a disconnection occurs, users have the auto-reconnect facility to re-connect the server again.
In case a disconnect has been detected, Socket.IO has a dedicated mechanism that locates whether the system is not responding from the client-side or the server-side.
A very useful feature of Socket.IO is that there is no need for reloading of refreshing the app or web page if the user wants to receive instant messages from chat apps such as Facebook Messenger or Whatsapp.
Socket.IO can also be used for push notifications so that users can receive instant notifications on their mobile devices or systems. It works for collaborative applications such as Google Docs and online gaming.
It s a great tool for developers that are looking to set up bidirectional real-time socket connections. With Socket.IO the implementation of simple applications like live chat is much easier. It is fast and reliable and since it is based on WebSockets, the app can call the server anytime without the need to reload the page. Socket.IO can be used for live chat but also for everything else that needs immediate communication between the visitors of the website or application.
