supercolliderjs: sclang timeout on electron build

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,
          "sclang": "/Applications/SuperCollider/SuperCollider.app/Contents/MacOS/sclang",
          "scsynth": "/Applications/SuperCollider/SuperCollider.app/Contents/Resources/scsynth",
          "stdin": false,

          },
          "sclang_conf": "/Users/lorenzo/Library/Application Support/SuperCollider/sclang_conf.yaml"
        }

          "syscall": "open",
          "code": "ENOENT",
          "path": "/Users/lorenzo/Library/Application Support/SuperCollider/sclang_conf.yaml"
        }
[ 101, 'connection open' ]

    version: '',
    stdout: '',

  }
}

How to reproduce this issue:

Create React App + Electron setup
On App.js use an electron channel to boot sclang

Environment

MacOS: 10.15
electron: 7.1.2

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!
