trop[bot] 8f0f8401f2 refactor: remove dead named-window lookup from guest-window-manager (#50496)
The frameNamesToWindow map was a holdover from the BrowserWindowProxy
IPC shim. Since nativeWindowOpen became the only code path, Blink's
FrameTree::FindOrCreateFrameForNavigation resolves named window targets
directly in the renderer, scoped to the opener's browsing context
group. When a matching named window exists, Blink navigates it without
ever sending a CreateNewWindow IPC to the browser, so this map was
never consulted in the legitimate same-opener case.

The only time the map found a match was when two unrelated renderers
happened to use the same target name, in which case openGuestWindow
would short-circuit before consuming the guest WebContents that
Chromium had already created for the new window, leaking it.

Adds a test verifying Blink handles same-opener named-target reuse
end-to-end without any browser-side tracking.

The Electron framework lets you write cross-platform desktop applications using JavaScript, HTML and CSS. It is based on Node.js and Chromium and is used by the Visual Studio Code and many other apps.

Follow @electronjs on Twitter for important announcements.

This project adheres to the Contributor Covenant code of conduct. By participating, you are expected to uphold this code. Please report unacceptable behavior to coc@electronjs.org.

Installation

To install prebuilt Electron binaries, use npm. The preferred method is to install Electron as a development dependency in your app:

npm install electron --save-dev

For more installation options and troubleshooting tips, see installation. For info on how to manage Electron versions in your apps, see Electron versioning.

Platform support

Each Electron release provides binaries for macOS, Windows, and Linux.

  • macOS (Monterey and up): Electron provides 64-bit Intel and Apple Silicon / ARM binaries for macOS.
  • Windows (Windows 10 and up): Electron provides ia32 (x86), x64 (amd64), and arm64 binaries for Windows. Windows on ARM support was added in Electron 5.0.8. Support for Windows 7, 8 and 8.1 was removed in Electron 23, in line with Chromium's Windows deprecation policy.
  • Linux: The prebuilt binaries of Electron are built on Ubuntu 22.04. They have also been verified to work on:
    • Ubuntu 18.04 and newer
    • Fedora 32 and newer
    • Debian 10 and newer

Electron Fiddle

Use Electron Fiddle to build, run, and package small Electron experiments, to see code examples for all of Electron's APIs, and to try out different versions of Electron. It's designed to make the start of your journey with Electron easier.

Resources for learning Electron

Programmatic usage

Most people use Electron from the command line, but if you require electron inside your Node app (not your Electron app) it will return the file path to the binary. Use this to spawn Electron from Node scripts:

const electron = require('electron')
const proc = require('node:child_process')

// will print something similar to /Users/maf/.../Electron
console.log(electron)

// spawn Electron
const child = proc.spawn(electron)
