Electron: Sending channel message from Main to Renderer

main-to-renderer.md

In main/index.js,

import { globalShortcut } from 'electron'

// mainWindow is an instance of BrowserWindow
let mainWindow;

app.on('ready', () => {
  globalShortcut.on('CommandOrControl+,', () => {
    mainWindow.webContents.send('shortcut-settings')
  })
})

In renderer/main.js,

import { ipcRenderer } from 'electron'

ipcRenderer.on('shortcut-settings', () => {
  // do whatever...
  // maybe, you're using vue, if so tell the router to go to the settings page.
  router.replace('/settings')
})
