Electronでデスクトップアプリのサンプル

YAPCでキーワードが出たので…

デスクトップアプリ作れるけどどうしたらいいのか…

参考

qiita.com
Electron
electron.atom.io

設定

npm
sudo npm -g install electron-prebuilt
mkdir electron-readus
cd electron-readus

init

$ npm init -y
This utility will walk you through creating a package.json file.
It only covers the most common items, and tries to guess sane defaults.

See `npm help json` for definitive documentation on these fields
and exactly what they do.

Use `npm install <pkg> --save` afterwards to install a package and
save it as a dependency in the package.json file.

Press ^C at any time to quit.

Is this ok? (yes)

ソース

index.html
<!DOCTYPE html>
<html>
  <head>
    <title>Hello World!</title>
  </head>
  <body>
    <h1>Hello World!</h1>
    We are using io.js <script>document.write(process.version)</script>
    and Electron <script>document.write(process.versions['electron'])</script>.
  </body>
</html>
index.js
var app = require('app');  // Module to control application life.
var BrowserWindow = require('browser-window');  // Module to create native browser window.

// Report crashes to our server.
require('crash-reporter').start();

// Keep a global reference of the window object, if you don't, the window will
// be closed automatically when the JavaScript object is GCed.
var mainWindow = null;

// Quit when all windows are closed.
app.on('window-all-closed', function() {
  // On OS X 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();
  }
});

// This method will be called when Electron has finished
// initialization and is ready to create browser windows.
app.on('ready', function() {
  // Create the browser window.
  mainWindow = new BrowserWindow({width: 800, height: 600});

  // and load the index.html of the app.
  mainWindow.loadUrl('file://' + __dirname + '/index.html');

  // Open the devtools.
  mainWindow.openDevTools();

  // Emitted when the window is closed.
  mainWindow.on('closed', function() {
    // 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.
    mainWindow = null;
  });
});

起動

electron .

できた
きちんとパッケージとしてなんかを行わないとデバッグモードって感じのようです

ようつべでコマンドの押下よりデスクトップの起動を確認

youtu.be

所感

基本、サンプルをコピペしただけなので動いた。なんかいろいろやればデスクトップアプリを作成できるかも
htmlだけでandroidiosアプリではなくデスクトップアプリも可能になってきたようです。
仕事の都合上、時間が取れない場合は他の技術で対応できるのは便利な感じ
