Pwa Development

This handles the full PWA implementation cycle from manifest generation to service worker setup and offline caching strategies. It's diagnostic driven, walking you through six states from "no PWA setup" to "production ready" with specific interventions at each level. The real value is in the caching strategy advisor and the iOS quirks handling, because iOS Safari is where PWAs get weird. Works with React, Svelte, and Next.js through their respective PWA plugins. The core principle is right: offline behavior can't be bolted on after the fact, it's an architectural decision about data flow and connectivity failure modes.

Files

PWA Development

Implement Progressive Web App features including service workers, caching strategies, offline support, and installation prompts for React and Svelte applications.

When to Use This Skill

Use this skill when:

Adding PWA capabilities to a web app
Implementing offline support
Creating service worker caching strategies
Debugging PWA installation issues
Handling iOS-specific PWA quirks

Do NOT use this skill when:

Building backend APIs
Working on requirements/design (use those skills first)
Need complex offline-first architecture (design first)

Core Principle

PWAs fail when offline behavior is an afterthought. A PWA is not "add service worker to existing app." It's a fundamental architectural decision about data flow, caching, and connectivity failure.
