“JS (Browser + Node.js): Broadcast Channel API - How to Reduce Server Load”

In this article I described the use case of combining Broadcast Channel API and Shared Workers (or Worker Threads in Node.js) for reducing the number of server connections.

Broadcast Channel API is a JavaScript interface that allows communication between different browsing contexts, such as tabs or frames (or between Node.js Worker Threads, but about this at the end of the article), that share the same origin. It provides a simple publish-subscribe model for sending and receiving messages between these contexts.

Shared Worker - a special type of web worker that can be accessed by multiple instances of an application. Shared workers have a single thread of execution and a shared scope between all clients, allowing for efficient communication and synchronization between tabs.

To know how to combine them - check the article.
