Notable Changes​

ASAR Integrity digest for improved security​

As of Electron 41, macOS Electron apps can now embed a digest of their ASAR Integrity information. This adds an additional layer of tamper detection for apps that use ASAR Integrity by validating the integrity information itself at app launch.

To enable the feature for your app, you can run the following command with @electron/asar v4.1.0 and above:

asar integrity-digest on /path/to/YourApp.app

You must re-sign your app afterwards. For more information, see the @electron/asar CLI documentation.

Support for this feature in Electron Forge is planned for the near future (electron/forge#4159).

Improved Wayland support​

On Wayland (Linux), frameless windows now have drop shadows and extended resize boundaries. To create fully frameless windows with no decorations, set hasShadow: false in the window constructor. #49885

Mitchell Cohen is writing a blog article about recent work to improve Electron's support of Wayland and client-side decorations on Linux. Watch this space!

Added support for MSIX auto-updating​

The Electron team recently added MSIX auto-updater support according to RFC #21. You can now ship both MSIX and Squirrel.Mac in your update server essentially with the same JSON response format. See the autoUpdater documentation for more information.

This was added in Electron 41 by #49586 and has also been backported to Electron 39.5.0 (#49585) and 40.2.0 (#49587).

Notable Changes​

ASAR Integrity graduates to stable​

A long-standing "experimental" feature -- ASAR integrity -- is now stable in Electron 39. When you enable this feature, it validates your packaged app.asar at runtime against a build-time hash to detect any tampering. If no hash is present or if there is a mismatch in the hashes, the app will forcefully terminate.

See the ASAR integrity documentation for full information on how on the feature works, on how to use it in your application, and how to use it in Electron Forge and Electron Packager.

In related news, Electron Packager v19 now enables ASAR by default. #1841

Google Summer of Code Begins​

Our two Google Summer of Code contributors have started the program's coding period!

• @nilayarya is crafting a new Save/Restore Window State API in Electron core. The new APIs will provide a built-in, standardized way to handle window state persistence. See Nilay's in-progress RFC at electron/rfcs#16.
• @hitarth-gg is hard at work modernizing the long-dormant Devtron extension using Chrome Manifest V3 APIs. This project will provide tooling for developers to debug IPC communication, track event listeners, and visualize module dependencies in their Electron applications.

It has been an exciting couple of weeks for our GSOC participants, so stay tuned for more updates!

Notable Changes​

Smooth Corners: Native CSS Squircles​

Electron 37 introduces the custom -electron-corner-smoothing CSS property, which allows apps to create smoother rounded corners to match Apple's macOS design language. This feature originally landed in Electron 36, but we felt like it deserved a brighter spotlight.

Example with 100% Corner Smoothing

Code	Result
.box { width: 128px; height: 128px; border-radius: 24px; -electron-corner-smoothing: 100%; }

Unlike the standard border-radius property, which carves quarter-circle corners out of a rectangle, -electron-corner-smoothing smoothly transitions the curve into a squircle shape with a continuous perimeter.

You can adjust the smoothness using values from 0% to 100%, or use the system-ui value to match the operating system's style (60% on macOS and 0% otherwise). This design enhancement can be applied on borders, outlines, and shadows, giving your app a subtle layer of polish.

Electron 36.0.0 has been released! It includes upgrades to Chromium 136, V8 13.6, and Node 22.14.0.

The Electron team is excited to announce the release of Electron 36.0.0! You can install it with npm via npm install electron@latest or download it from our releases website. Continue reading for details about this release.

Notable Changes​

Writing Tools Support​

In Electron 36, you can enable macOS system-level features like Writing Tools (spelling and grammar), Autofill, and Services menu items in your context menus. To do so, pass a WebFrameMain instance into the frame parameter for menu.popup().

import { BrowserWindow, Menu, WebFrameMain } from 'electron';

const currentWindow = BrowserWindow.getFocusedWindow();
const focusedFrame = currentWindow.webContents.focusedFrame;
const menu = Menu.buildFromTemplate([{ label: 'Copy', role: 'copy' }]);

menu.popup({
  window: currentWindow,
  frame: focusedFrame,
});

Electron 35.0.0 has been released! It includes upgrades to Chromium 134.0.6998.44, V8 13.5, and Node 22.14.0.

Notable Changes​

Service Worker Preload Scripts for Improved Extensions Support​

Originally proposed in RFC #8 by @samuelmaddock, Electron 35 adds the ability to attach a preload script to Service Workers. With Chrome's Manifest V3 Extensions routing a lot of work through extension service workers, this feature fills in a gap in Electron's support for modern Chrome extensions.

When registering a preload script programmatically at the Session level, you can now specifically apply it to Service Worker contexts with the ses.registerPreloadScript(script) API.

// Add our preload realm script to the session.
session.defaultSession.registerPreloadScript({
  // Our script should only run in service worker preload realms.
  type: 'service-worker',
  // The absolute path to the script.
  script: path.join(__dirname, 'extension-sw-preload.js'),
});

Furthermore, IPC is now available between Service Workers and their attached preload scripts via the ServiceWorkerMain.ipc class. The preload script will still use the ipcRenderer module to communicate with its Service Worker. See the original RFC for more details.

This feature was preceded by many other changes that laid the groundwork for it:

• #45329 redesigned the Session module's preload APIs to support registering and unregistering individual preload scripts.
• #45229 added the experimental contextBridge.executeInMainWorld(executionScript) script to evaluate JavaScript in the main world over the context bridge.
• #45341 added the ServiceWorkerMain class to interact with Service Workers in the main process.

Electron 34.0.0 has been released! It includes upgrades to Chromium 132.0.6834.83, V8 13.2, and Node 20.18.1.

Notable Changes​

HTTP Compression Shared Dictionary Management APIs​

HTTP compression allows data to be compressed by a web server before being received by the browser. Modern versions of Chromium support Brotli and Zstandard, which are newer compression algorithms that perform better for text files than older schemes such as gzip.

Custom shared dictionaries further improve the efficiency of Brotli and Zstandard compression. See the Chrome for Developers blog on shared dictionaries for more information.

@felixrieseberg added the following APIs in #44950 to manage shared dictionaries at the Session level:

• session.getSharedDictionaryUsageInfo()
• session.getSharedDictionaryInfo(options)
• session.clearSharedDictionaryCache()
• session.clearSharedDictionaryCacheForIsolationKey(options)

Unresponsive Renderer JavaScript Call Stacks​

Electron's unresponsive event occurs whenever a renderer process hangs for an excessive period of time. The new WebFrameMain.collectJavaScriptCallStack() API added by @samuelmaddock in #44204 allows you to collect the JavaScript call stack from the associated WebFrameMain object (webContnets.mainFrame).

This API can be useful to determine why the frame is unresponsive in cases where there's long-running JavaScript events causing the process to hang. For more information, see the proposed web standard Crash Reporting API.

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

app.commandLine.appendSwitch(
  'enable-features',
  'DocumentPolicyIncludeJSCallStacksInCrashReports',
);

app.on('web-contents-created', (_, webContents) => {
  webContents.on('unresponsive', async () => {
    // Interrupt execution and collect call stack from unresponsive renderer
    const callStack = await webContents.mainFrame.collectJavaScriptCallStack();
    console.log('Renderer unresponsive\n', callStack);
  });
});
