Awaiting win.loadURL in createWindow() blocks events from firing

[skulls-dot-codes]

Describe the bug The template for background.js uses await win.loadURL(process.env.WEBPACK_DEV_SERVER_URL) to load the vue server in development. For some reason this prevents the dom-ready, did-finish-load, ready-to-show events in the main process from firing reliably and also the mounted event in vue.

To Reproduce Create a new project and create listeners for any of the events above. They most likely will not fire. Removing await from win.loadURL will allow these events to fire.

Expected behavior The development server or build process should not interfere with the events.

Environment (please complete the following information): Custom vue.config.js to enable node integration:

module.exports = {
  pluginOptions: {
    electronBuilder: {
      nodeIntegration: true
    }
  }
}

Hmm, this is an interesting issue. I added the await because it fixed some issues with devtools, but I think using .then would work for that. Try using this code and let me know if it fixes your issue:

win.loadURL(process.env.WEBPACK_DEV_SERVER_URL).then(() => {
      if (!process.env.IS_TEST) win.webContents.openDevTools()
    })

Old issue I know, sorry, but just wanted to +1 and say I also had this issue and was scratching my head as to why the events weren't firing.

Removed async / await from my window creation functions, used .then() and they started working..!
