Split out of #55229 and extended per review there. - heapsnapshot-helpers.js reads V8's flat snapshot arrays: takeHeapSnapshot()/parseHeapSnapshot(), countHeapSnapshotNodes(), snapshotContainsRetainingPath() and countRetainingPathNodes(). Path steps skip weak edges and can also match edge type, edge name, node type and detachedness; each node counts once however many paths reach it. The old object-graph containsRetainingPath() is removed. - Every recordState() + containsRetainingPath() check in cpp-heap.spec.ts uses the new helpers, and --expose-internals is dropped. - The node-counting checks (powerMonitor, autoUpdater, the two webContents before/after counts and api-ipc's ObjectTemplateInfo count) use countHeapSnapshotNodes() over the node array; the occurrences checks (three Session roots, one WebFrameMain root) count distinct nodes. - The renderer cached-templates test keeps webContents.takeHeapSnapshot() and counts its markers with countHeapSnapshotNodes() instead of createJSHeapSnapshot(). - Tests that make the remote app quit inside remotely() register their exit/close listener first, so a fast exit is not missed (19 tests). - 'should settle an in-flight call stack reply after frame disposal' keeps the page running script so the V8 interrupt is serviced, and awaits the result instead of racing a 5 s timeout. - 'should release the root for a detached frame after navigation' runs its app with --disable-renderer-backgrounding so the old page's unload IPC is not dropped.

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.

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 (Ventura and up): Electron provides 64-bit Intel and Apple Silicon / ARM binaries for macOS.
- Windows (Windows 10 and up): Electron provides
x64(amd64) andarm64binaries for Windows. - Linux: Electron provides
x64(amd64) andarm64binaries for Linux. Electron supports major Linux distributions (e.g., Ubuntu, Fedora, Debian) in versions that are still supported by both Chromium and the distro maker (without requiring a paid subscription). The prebuilt binaries are built on Ubuntu.
In general, Electron tries to align with Chromium on platform support.
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.

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)
