What problem does it solve? Setting up a cross-platform app normally means wiring Ionic, Capacitor, and Electron together by hand, duplicating configuration across web, Android, and desktop targets. This Skill guides the ionic-everywhere CLI so a single TypeScript codebase scaffolds, syncs, and builds to all three platforms with consistent tooling. ## Core Features & Use Cases - Project Scaffolding: Run ionic-everywhere new with flags for app ID, package manager, layout (tabs/drawer/sidebar), styling (Tailwind, shadcn, Kumo), and theme to generate a complete project. - Environment Validation: Use ionic-everywhere doctor to verify Node.js, bun/npm, JDK 21+, and Android SDK before building. - Platform Management: Add Android or Electron desktop shells to an existing project with ionic-everywhere add, then build APKs or desktop installers via generated npm scripts. - Use Case: A developer wants one responsive Ionic React app shipped as a PWA, a Google Play APK, and a Windows/macOS/Linux desktop app. Scaffold once with the CLI, then run npm run sync and npm run build:all to produce every target from the same source tree. ## Quick Start Ask the agent to scaffold a new cross-platform Ionic app named my-app with default options using the ionic-everywhere CLI.
