elegantapp/pwa-asset-generator

pwa-asset-generator is a command-line tool that automates the creation and declaration of assets for progressive web applications.

The tool solves the problem of manually generating multiple icon and splash screen variants across different platforms and sizes. It takes a single source image and automatically generates icons, splash screens, favicons, and mstile images in the dimensions required by Android, iOS, and web standards. It then updates the manifest.json and index.html files with the appropriate image declarations, following Web App Manifest specifications and Apple Human Interface guidelines. This eliminates the tedious work of creating dozens of image variants and hand-coding their references into configuration files.

The tool is suited for developers building PWAs who want to support installation on both Android and iOS devices without manually managing asset generation. It handles the complexity of platform-specific requirements, including the varying icon sizes expected by Google Play and Apple's guidelines. Anyone building a PWA that targets multiple platforms should consider it, as it significantly reduces the setup overhead for asset management.

The project maintains active continuous integration with automated testing on each change. Releases follow semantic versioning conventions, ensuring predictable version increments. The tool uses Puppeteer for image rendering and generation, providing reliable cross-platform asset creation. Development activity shows consistent maintenance with regular updates to keep pace with evolving PWA standards and platform requirements.
