audio-only-youtube chrome extension enables you to disable only video on youtube songs which saves bandwidth when you want to listen songs on youtube.

Note: It doesn't support Youtube live videos.

You can install extension from here(Chrome Webstore)

1. After cloning the repo, run yarn run start.
2. Open chrome, go to extensions tab, load unpacked extension and select dev/build directory.
3. Go to Youtube and see extension in live.

In case you edit code, it would automatically rebuild the extension and after that you need to reload it in the browser.

Thanks to Stefan Ivic for all the icons used in the extension.

The only reason this extension is able to work is because Youtube serves audio and video streams separately. This extension intercepts response of all the requests on the youtube domains. In the response headers, it checks for Content-Type. If it's an audio file, then it assumes that we have got the audio stream for the video being played. It removes certain range related query parameters in accordance with HTTP RFC's range requests section. Then we set the source of Youtube's video player to audio stream.

Good luck!
