For the last two years, Electron has helped developers build cross platform desktop apps using HTML, CSS, and JavaScript. Now we're excited to share a major milestone for our framework and for the community that created it. Выпуск Electron 1.0 теперь доступен в electronjs.org.

Electron 1.0 represents a major milestone in API stability and maturity. This release allows you to build apps that act and feel truly native on Windows, Mac, and Linux. Building Electron apps is easier than ever with new docs, new tools, and a new app to walk you through the Electron APIs.

Если вы готовы создать свое первое приложение Electron, вот быстрый старт поможет вам начать работу.

Нам не терпится увидеть, что вы создадите с Electron.

Путь Electron​

Мы выпустили Electron, когда мы запустили Atom чуть более двух лет назад. Electron, тогда известный как Atom Shell, был фреймворком, на котором мы построили Atom. In those days, Atom was the driving force behind the features and functionalities that Electron provided as we pushed to get the initial Atom release out.

Теперь вождение Electron является растущим сообществом разработчиков и компаний строит все на основе электронной почты, чата, и Git-приложения для Инструменты аналитики SQL, клиентов торрентов, и робота.

In these last two years we've seen both companies and open source projects choose Electron as the foundation for their apps. Just in the past year, Electron has been downloaded over 1.2 million times. Ознакомьтесь с некоторыми из удивительных приложений Electron и добавьте свои собственные приложения, если они еще не там.

Демонстрации Electron API​

Along with the 1.0 release, we're releasing a new app to help you explore the Electron APIs and learn more about how to make your Electron app feel native. Along with the 1.0 release, we're releasing a new app to help you explore the Electron APIs and learn more about how to make your Electron app feel native.

Devtron​

Мы также добавили новое расширение, которое поможет вам отлаживать ваши приложения Electron. Devtron является открытым исходным кодом расширением для Инструментов разработчика Chrome , призванных помочь вам проверить, отладка и устранение неполадок вашего приложения Electron.

Функции​

• Require graph that helps you visualize your app's internal and external library dependencies in both the main and renderer processes
• IPC monitor that tracks and displays the messages sent and received between the processes in your app
• Event inspector that shows you the events and listeners that are registered in your app on the core Electron APIs such as the window, app, and processes
• App Linter that checks your apps for common mistakes and missing functionality

Spectron​

Наконец, мы выпускаем новую версию Spectron, интеграцию тестирования фреймворка для Electron приложений.

Spectron 3.0 has comprehensive support for the entire Electron API allowing you to more quickly write tests that verify your application's behavior in various scenarios and environments. Спектр основан на ChromeDriver и WebDriverIO , поэтому у него также полные API для навигации по страницам, пользователь вводит и выполняет JavaScript.

Сообщество​

Electron 1.0 is the result of a community effort by hundreds of developers. Outside of the core framework, there have been hundreds of libraries and tools released to make building, packaging, and deploying Electron apps easier.

Сейчас появилась новая страница сообщества с описанием многих замечательных инструментов Electron, приложений, библиотек и фреймворков. Вы также можете проверить Electron и Electron Userland , чтобы увидеть некоторые из этих фантастических проектов.

Впервые встречаете? Посмотрите вступительное видео Electron 1.0:

Electron 0.37 was recently released and included a major upgrade from Chrome 47 to Chrome 49 and also several new core APIs. This latest release brings in all the new features shipped in Chrome 48 and Chrome 49. This includes CSS custom properties, increased ES6 support, KeyboardEvent improvements, Promise improvements, and many other new features now available in your Electron app.

What's New​

CSS Custom Properties​

If you've used preprocessed languages like Sass and Less, you're probably familiar with variables, which allow you to define reusable values for things like color schemes and layouts. Variables help keep your stylesheets DRY and more maintainable.

CSS custom properties are similar to preprocessed variables in that they are reusable, but they also have a unique quality that makes them even more powerful and flexible: they can be manipulated with JavaScript. This subtle but powerful feature allows for dynamic changes to visual interfaces while still benefitting from CSS's hardware acceleration, and reduced code duplication between your frontend code and stylesheets.

For more info on CSS custom properties, see the MDN article and the Google Chrome demo.

CSS Variables In Action​

Let's walk through a simple variable example that can be tweaked live in your app.

:root {
  --awesome-color: #a5ecfa;
}

body {
  background-color: var(--awesome-color);
}

The variable value can be retrieved and changed directly in JavaScript:

// Get the variable value ' #A5ECFA'
let color = window
  .getComputedStyle(document.body)
  .getPropertyValue('--awesome-color');

// Set the variable value to 'orange'
document.body.style.setProperty('--awesome-color', 'orange');

The variable values can be also edited from the Styles section of the development tools for quick feedback and tweaks:

KeyboardEvent.code Property​

Chrome 48 added the new code property available on KeyboardEvent events that will be the physical key pressed independent of the operating system keyboard layout.

This should make implementing custom keyboard shortcuts in your Electron app more accurate and consistent across machines and configurations.

window.addEventListener('keydown', function (event) {
  console.log(`${event.code} was pressed.`);
});

Check out this example to see it in action.

Promise Rejection Events​

Chrome 49 added two new window events that allow you to be notified when an rejected Promise goes unhandled.

window.addEventListener('unhandledrejection', function (event) {
  console.log('A rejected promise was unhandled', event.promise, event.reason);
});

window.addEventListener('rejectionhandled', function (event) {
  console.log('A rejected promise was handled', event.promise, event.reason);
});

Check out this example to see it in action.

ES2015 Updates in V8​

The version of V8 now in Electron incorporates 91% of ES2015. Here are a few interesting additions you can use out of the box—without flags or pre-compilers:

Default parameters​

function multiply(x, y = 1) {
  return x * y;
}

multiply(5); // 5

Деструктирующее присваивание​

Chrome 49 added destructuring assignment to make assigning variables and function parameters much easier.

This makes Electron requires cleaner and more compact to assign now:

Browser Process Requires​

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

Renderer Process Requires​

const { dialog, Tray } = require('electron').remote;

Other Examples​

// Destructuring an array and skipping the second element
const [first, , last] = findAll();

// Destructuring function parameters
function whois({ displayName: displayName, fullName: { firstName: name } }) {
  console.log(`${displayName} is ${name}`);
}

let user = {
  displayName: 'jdoe',
  fullName: {
    firstName: 'John',
    lastName: 'Doe',
  },
};
whois(user); // "jdoe is John"

// Destructuring an object
let { name, avatar } = getUser();

Новые API Electron​

Ниже приведены некоторые из новых API Electron, а также вы можете ознакомиться с каждым новым API в примечаниях к релизам Electron releases.

События show и hide для BrowserWindow​

Эти события происходят, когда окно показывается или скрывается.

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

let window = new BrowserWindow({ width: 500, height: 500 });
window.on('show', function () {
  console.log('Окно было отображено');
});
window.on('hide', function () {
  console.log('Окно было скрыто');
});

platform-theme-changed на app для OS X​

Это событие возникает, когда переключается системная тема Dark Mode.

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

app.on('platform-theme-changed', function () {
  console.log(`Тема платформы изменена. Тёмный режим? ${app.isDarkMode()}`);
});

app.isDarkMode() для OS X​

Этот метод возвращает true, если система находится в темном режиме, и false в противном случае.

События scroll-touch-begin и scroll-touch-end в BrowserWindow для OS X​

Эти события возникают, когда начинается или заканчивается фаза событий при прокрутке.

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

let window = new BrowserWindow({ width: 500, height: 500 });
window.on('scroll-touch-begin', function () {
  console.log('Прокрутка касанием началась');
});
window.on('scroll-touch-end', function () {
  console.log(''Прокрутка касанием закончилась'');
});

Since the beginning of Electron, starting way back when it used to be called Atom-Shell, we have been experimenting with providing a nice cross-platform JavaScript API for Chromium's content module and native GUI components. The APIs started very organically, and over time we have made several changes to improve the initial designs.

Now with Electron gearing up for a 1.0 release, we'd like to take the opportunity for change by addressing the last niggling API details. The changes described below are included in 0.35.x, with the old APIs reporting deprecation warnings so you can get up to date for the future 1.0 release. An Electron 1.0 won't be out for a few months so you have some time before these changes become breaking.

Deprecation warnings​

By default, warnings will show if you are using deprecated APIs. To turn them off you can set process.noDeprecation to true. To track the sources of deprecated API usages, you can set process.throwDeprecation to true to throw exceptions instead of printing warnings, or set process.traceDeprecation to true to print the traces of the deprecations.

New way of using built-in modules​

Встроенные модули теперь сгруппированы в один модуль, а не разделены на независимые модули, так что вы можете использовать их без конфликтов с другими модулями:

var app = require('electron').app;
var BrowserWindow = require('electron').BrowserWindow;

The old way of require('app') is still supported for backward compatibility, but you can also turn if off:

require('electron').hideInternalModules();
require('app'); // throws error.

An easier way to use the remote module​

Because of the way using built-in modules has changed, we have made it easier to use main-process-side modules in renderer process. You can now just access remote's attributes to use them:

// New way.
var app = require('electron').remote.app;
var BrowserWindow = require('electron').remote.BrowserWindow;

Instead of using a long require chain:

// Old way.
var app = require('electron').remote.require('app');
var BrowserWindow = require('electron').remote.require('BrowserWindow');

Splitting the ipc module​

The ipc module existed on both the main process and renderer process and the API was different on each side, which is quite confusing for new users. We have renamed the module to ipcMain in the main process, and ipcRenderer in the renderer process to avoid confusion:

// В main процессе.
var ipcMain = require('electron').ipcMain;

// In renderer process.
var ipcRenderer = require('electron').ipcRenderer;

And for the ipcRenderer module, an extra event object has been added when receiving messages, to match how messages are handled in ipcMain modules:

ipcRenderer.on('message', function (event) {
  console.log(event);
});

Standardizing BrowserWindow options​

The BrowserWindow options had different styles based on the options of other APIs, and were a bit hard to use in JavaScript because of the - in the names. They are now standardized to the traditional JavaScript names:

new BrowserWindow({ minWidth: 800, minHeight: 600 });

Following DOM's conventions for API names​

The API names in Electron used to prefer camelCase for all API names, like Url to URL, but the DOM has its own conventions, and they prefer URL to Url, while using Id instead of ID. We have done the following API renames to match the DOM's styles:

• Url is renamed to URL
• Csp is renamed to CSP

You will notice lots of deprecations when using Electron v0.35.0 for your app because of these changes. An easy way to fix them is to replace all instances of Url with URL.

Changes to Tray's event names​

The style of Tray event names was a bit different from other modules so a rename has been done to make it match the others.

• clicked is renamed to click
• double-clicked is renamed to double-click
• right-clicked is renamed to right-click
