sclang timeout on electron build

See original GitHub issue

Sclang booting reaches timeout on electron but only on the production build.

This is the log:

Loading config: /Users/lorenzo/Developer/Node/superorch/.supercollider.yaml
debug  : {
          "debug": true,
          "echo": true,

        }

On App.js use an electron channel to boot sclang

Environment

Ok, I’ve found a solution.

Basically every module required by supercolliderjs must be unpacked, therefore being located inside MyApp/Contents/Resources/app.asar.unpacked.

Also all path statements that involve unpacked modules should be modified to point to app.asar.unpacked rather then app.asar. To do this I have found this library called hazardous that does that for you.

@crucialfelix I’ve created an example repo that you can use as a reference. https://github.com/lorenzorivosecchi/electron-with-supercollider-example

Sorry, it’s been the craziest week of the year. I’ll have a chance to peek at that over the holidays. Thanks!
