How to Build a Bitcoin price alert using Chrome Extension and JavaScript

Step by Step guide to building a Bitcoin alert system using Chrome extensions and regular JavaScript

I’ve built a small extension for Google Chrome that automatically alerts me when the Bitcoin price goes up or down. For this purpose, the extension allows us to configure two alerts.

I’ve created it for two reasons: The first one to avoid being distracted looking at the price of Bitcoin in different pages, and the second reason because I wanted to do something fast and practical that would let me know if the price change.

The extension I have created is straightforward but useful, and I encourage you to improve it and add more options.
