Notifications, Push Notifications, Socket Handling and Server Side Events in JavaScript

The article discusses how to build a simple notification system in a web application using Server-Sent Events (SSE) and Socket.IO technologies. The author starts by explaining what SSE and Socket.IO are and their applications in modern web applications. SSE is a communication method that enables a server to asynchronously send updates to clients through a simple HTTP connection. On the other hand, Socket.IO is a library that facilitates bidirectional communication between servers and clients, making it an ideal solution for handling notifications, chats, and other dynamic interfaces. The author also provides practical examples of implementing notifications within an application, making the article a useful guide. Moreover, the article includes best practices and common pitfalls to avoid while implementing this functionality. It concludes with a typical summary and encourages readers to experiment with the suggestions provided in the text.
