如何设置基于 AngularCLI 的 Electron 项目，并进行调试/实时重新加载？

Question

我正在尝试设置一个 AngularCLI 项目，该项目可以在浏览器中和通过电子运行。

我找到了一些很好的教程，比如这篇文章：

但是我找不到或找出允许在电子项目中实时重新加载和调试的设置。

假设您使用的是@angular/cli：

• 在src文件夹旁边创建一个文件夹electron
• 在此文件夹中，创建一个文件electron.js

在其中粘贴以下内容：

const {app, BrowserWindow} = require('electron');

// 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();
  win.maximize();

  // and load the index.html of the app
  win.loadURL(`file://${__dirname}/index.html`);

  // ----------------------------------------------------------------
  //           THIS IS WHAT YOU'RE LOOKING FOR DEBUGGING
  // open the DevTools
  win.webContents.openDevTools()
  // ----------------------------------------------------------------

  // emitted when the window is closed
  win.on('closed', () => {
    // fereference 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;
  });
};

// yhis 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();
  }
});

• 在同一文件夹中，创建一个文件generate-package-json.json。这样我们就可以像这样为我们的电子应用程序自动生成包：

文件：

const fs = require('fs');

const package = `{ "name": "${ require('../package.json').name}", "version": "${ require('../package.json').version}", "main": "electron.js" }`;

fs.writeFile('./dist/package.json', package, err => {
  if (err) {
    return console.log(err);
  }
});

然后在你的 package.json 中：

{
  ...
  scripts: {
    "build-electron": "npm run build -- -bh='./'; node ./electron/generate-package-json.js; cp ./electron/electron.js dist/",
    "electron": "npm run build-electron; electron dist/"
  }
  ...
}

最后，运行npm run electron
