kaiku-music-player | Kaiku Music Player for Winamp nostalgic | Music Player library

I have a music player built with Electron.

I am having some performance / process blocking that I didn't expect. I am trying to do some background processes for heavy IO operations. (determining songs duration and album covers)

I am doing this by calling methods through the electron.remote module. I have noticed that the app didn't do these things asynchronously somehow.

I have been running the performance tool to check and saw the click handler taking a huge time.

Digging deeper I found that ipcRenderer.sendSync is called.

There is a warning about sendSync blocking nature in Electron Docs. But, my own code does not call it. So I suspect the remote module or something else in my code causing sendSync to be called.

The entire app code is on Github but here is an example of electron.remote usage.

The gist is something like this:
