Using a Chrome Extension and Node server to save the current song and artisit information to a text file for use in streaming software like OBS or Xsplit.
This is my solution to the problem of no API support from Amazon Music. The Chrome Extension simply checks if I'm playing music and if I am then passes the song title and artist from contentScript.js to background.js. From the background script we just make a simple POST to the Node (express.js) server. From there the server writes the data to a text file. We can not write to a file from within the browser, so we need to extract it and make an API call. The Develop Extenions Docs are helpful if you want to better understand how the content and backgroud scripts work.
You'll need to add a logs folder to the project or change the output location of the text files.
You'll need to install express and cors for this project.
Open up your Chrome browser and in a new tab go to chrome://extensions. On the extensions page enable 'Developer Mode' and click 'Load Unpacked'. Navigate to the project location and select the extension folder to install. You'll need to toggle the extension on when you want to use it, otherwise I leave it off.
Once the extension is installed and enabled, load up a tab with Amazon Music. Start the server node app.js and start playing music. When the server receives the song data it will console log it and write it to the text file. The POST to the server only happens if the song changes. The content script checks every 2 seconds for a song change.
