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:

Layer 1

Transport Security

HTTPS encryption ensures data integrity between your server and users.

Layer 2

Content Security Policy

CSP headers prevent XSS attacks by controlling which resources can load.

Layer 3

Secure Headers

Additional headers prevent clickjacking, MIME sniffing, and information leakage.

Layer 4

Service Worker Scope

Limited scope ensures the service worker only controls intended resources.
