Electron

Example

A basic election application looks like:

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

let win;
function init() {
  win = NewBrowserWindow({
    width: 800,
    height: 600,
    webPreferences: {
      contextIsolation: true,
      nodeIntegration: false,
      preload: path.join(__dirname, "preload.js")
    }
  });

  win.loadFile(path.join(__dirname, "index.html"));

  win.on("closed", () => {
    win = null;
  });
}

app.on("ready", init);

app.on("window-all-closed", () => {
  if (process.platform !== "darwin") {
    app.quit();
  }
});

app.on("activate", () => {
  if (win === null) {
    init()
  }
});

Installation

Using npm(1):

npm install --save-dev electron

See [[NodeJS/ElectronBuilder|here]] for details on how to use '''Electron Builder''' in a project.

See [[https://www.electronjs.org/docs/tutorial/application-distribution#manual-distribution|here]] for instructions on manually building an Electron app, optionally with source code obfuscation.

-=== Menu Bar ===

The '''menu bar''' is composed of menus and sub-menus. Design a 'template' (see below) and have it built into a menu, then apply the menu to the application.

{{{
const { app, BrowserWindow, menu, shell } = require("electron");

const template = [
  {
    label: 'File',
    submenu: [
      {
        label: 'Exit',
        click() {
          app.quit()
        }
      }
    ]
  },
  {
    label: 'Help',
    submenu: [
      {
        label: 'Learn More',
        click: async () => {
          await shell.openExternal('https://example.org');
        }
      }
    ]
  }
];

const menu = Menu.buildFromTemplate(template);
Menu.setApplicationMenu(menu);
}}}

The above example features two ways to define the corresponding action for a menu item, and it also demonstrates how an async function can be used.

-=== Keyboard Shortcuts ===

==== Built-in Method ====

Follow the above example for menu items, but add an `accelerator` option to the corresponding menu item.

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

const template = [
  {
    label: 'File',
    submenu: [
      {
        label: 'Save',
        accelerator: 'CmdOrCtrl+S',
        click: saveFile()
      }
    ]
  }
]

-A simpler method is to use the `electron-localshortcut` package.

-The helper modifier `CmdOrCtrl` exists to simplify this need as shown in the above examples. Nonetheless, it is possible to re-invent the wheel.

const { app, BrowserWindow, menu } = require("electron");
const isMac = process.platform === 'darwin';

const template = [

    label: 'File',
