Why Security Matters
Progressive Web Apps have access to powerful APIs: push notifications, background sync, camera access, and more. With great power comes great responsibility. This starter template prioritizes security from day one.
The Architecture
This PWA uses a modern architecture designed for both developer experience and production reliability:
- Vite — Lightning-fast builds and hot module replacement
- Workbox — Google's library for reliable service workers
- Docker — Consistent deployments across environments
- Nginx — High-performance web server with security headers
Security Layers
Security isn't a single feature—it's a series of layers working together:
Transport Security
HTTPS encryption ensures data integrity between your server and users.
Content Security Policy
CSP headers prevent XSS attacks by controlling which resources can load.
Secure Headers
Additional headers prevent clickjacking, MIME sniffing, and information leakage.
Service Worker Scope
Limited scope ensures the service worker only controls intended resources.
