electron by hairyf/skills

Electron embeds Chromium and Node.js so you can ship one JavaScript codebase for Windows, macOS, and Linux. Use these skills when scaffolding projects, wiring main/renderer IPC, configuring security and packaging, or integrating native modules and auto-updates.

The skill is based on Electron (latest), generated at 2026-01-30.
