Preload script is not executed with newer electron versions.

[JanisErdmanis]

Hello,

yesterday I started to learn javascript and electron with a target to add menu item which executes some command as argument taking a value from web page. Since I found app which does these things I started to learn from It. My issue is that for electron version larger than v0.37.0 my preload script does not gets executed.

I add to main.js prelaod script in this way

   mainWindow = new BrowserWindow({             // Instantiate the browser window.
        width: 1024,
        height: 768,
        preload: __dirname+'/preload.js'
    }); 

where in preload.js I simply add

console.log('preloading')

Is it a bug or I should load preload.js differently now?

• Electron version: v1.4.5 and v0.37.0
• Operating system: Ubuntu 16.04

The preload attribute on the top-level options object was deprecated pre-Electron 1.0 and removed from the 1.0 API.

It should now be set on the nested webPreferences object:

 mainWindow = new BrowserWindow({             // Instantiate the browser window.
  width: 1024,
  height: 768,
  webPreferences: {
    preload: __dirname+'/preload.js'
  }
}); 

See http://electron.atom.io/docs/api/browser-window/#new-browserwindowoptions for more details.

Disappointing that I did not saw error message for deprecated feature :/ But now it works. Thank You :)
