Go to Crypto Tab Tracker.
Happy new year! Over the weekend, I built a real-time cryptocurrency tracker that displays the current USD value of a given coin in a desktop browser tab. I created this little project because I wanted a quick way to check up on certain coins I'm holding in my portfolio, notably XRB. Pushing the price into the page title, thus the tab text, was a simple solution. Crypto Tab Tracker utilizes the Coin Market Cap API.
The top 20 cryptocurrencies, determined by market cap, are populated to the header for easy access. However, any coin listed on Coin Market Cap can be tracked by modifying the track parameter in the URL.
At the time of this writing, January 1, 2018, the top 10 cryptocurrencies are Bitcoin, Ripple, Ethereum, Bitcoin Cash, Cardano, Litecoin, IOTA, Stellar, NEM, and Dash. I expect huge market growth in 2018, with some new coins rising to the top and dethroning the once-dominant. This will surely be an exciting year for crypto as a whole.
You can check out the project's repo on GitHub here. Note: this project works as intended on most modern desktop browsers.
