• Reference: https://electron.atom.io/docs/tutorial/quick-start/

1. ng new electron-demo
2. cd electron-demo
3. 調整.angular-cli.json中的assets

   "assets": [
       {
         "glob": "main.js",
         "input": "../",
         "output": "./"
       },
       {
         "glob": "package.json",
         "input": "../",
         "output": "./"
       }
     ]

4. 新增main.js

   const {app, BrowserWindow} = require('electron')
   const path = require('path')
   const url = require('url')
   
   // Keep a global reference of the window object, if you don't, the window will
   // be closed automatically when the JavaScript object is garbage collected.
   let win
   
   function createWindow () {
   // Create the browser window.
   win = new BrowserWindow({width: 800, height: 600})
   
   // and load the index.html of the app.
   win.loadURL(url.format({
       pathname: path.join(__dirname, 'index.html'),
       protocol: 'file:',
       slashes: true
   }))
   
   // Open the DevTools.
   win.webContents.openDevTools()
   
   // Emitted when the window is closed.
   win.on('closed', () => {
           // Dereference the window object, usually you would store windows
           // in an array if your app supports multi windows, this is the time
           // when you should delete the corresponding element.
           win = null
       })
   }
   
   // This method will be called when Electron has finished
   // initialization and is ready to create browser windows.
   // Some APIs can only be used after this event occurs.
   app.on('ready', createWindow)
   
   // Quit when all windows are closed.
   app.on('window-all-closed', () => {
       // On macOS it is common for applications and their menu bar
       // to stay active until the user quits explicitly with Cmd + Q
       if (process.platform !== 'darwin') {
           app.quit()
       }
   })
   
   app.on('activate', () => {
       // On macOS it's common to re-create a window in the app when the
       // dock icon is clicked and there are no other windows open.
       if (win === null) {
           createWindow()
       }
   })
   
   // In this file you can include the rest of your app's specific main process
   // code. You can also put them in separate files and require them here.

5. package.json中的scripts

   "scripts": {
       "start": "ng build && concurrently --raw \"ng build -w\" \"electron ./dist\""
   }

6. package.json中加入"main": "main.js"
7. npm install --save-dev electron concurrently
8. 調整index.html中的<base href="/">改為<base href="./">
9. npm start
