claude[bot]andClaude 2454be571a test: parse all custom page size PDFs in one pdf.js process (#54491)
`printToPDF() with custom page sizes` printed 11 page sizes and called
readPDF() on each one. Every readPDF() call starts a full Electron
process to run pdf.js. On macOS x64 CI, with the parallel vitest
workers, that is about 2-5s per call, so the loop often went over the
30s test timeout.

Add readPDFs(), which parses several PDFs in one pdf-reader process.
The test now prints every size first and then parses them all with a
single launch. readPDF() is now a wrapper around readPDFs().

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 (Ventura and up): Electron provides 64-bit Intel and Apple Silicon / ARM binaries for macOS.
  • Windows (Windows 10 and up): Electron provides x64 (amd64) and arm64 binaries for Windows.
  • Linux: Electron provides x64 (amd64) and arm64 binaries 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.

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)
