Add web platform with PWA support via universal adapter architecture

[Copilot]

Ports Dyad to run as a Progressive Web App while maintaining full Electron desktop compatibility. Same codebase, dual deployment targets.

Architecture

Universal Adapter Pattern: Platform-agnostic interfaces abstract Electron vs. web differences.

// Application code unchanged - uses adapters
import { ipcClient } from '@/adapters/ipc-adapter';
import { fileSystem } from '@/adapters/filesystem-adapter';
import { database } from '@/adapters/database-adapter';

// Works in both Electron and web automatically
const result = await ipcClient.invoke('some-method', data);
const files = await fileSystem.readDir('/path');
const rows = await database.query('SELECT * FROM apps');

Platform Detection: src/lib/platform.ts - isElectron() / isWeb() runtime detection

Implementation

Adapters (711 LOC)

• IPC Adapter (196 lines): Electron IPC ↔ HTTP REST API + WebSocket
• FileSystem Adapter (331 lines): Native fs → File System Access API → virtual fs fallback
• Database Adapter (184 lines): SQLite → IndexedDB → PostgreSQL

Backend (230 lines)

• Express server (src/server/index.ts): REST endpoints at /api/:method, WebSocket at /ws/:channel
• Security: Helmet, CORS, CSP, session management
• Middleware: Compression, body parsing, error handling

PWA (193 lines)

• Service Worker (src/web/service-worker.ts): Network-first caching, auto-updates
• Manifest (public/manifest.json): App metadata, icons, install config
• Install UI (src/components/PWAInstallPrompt.tsx): Native install prompt

Deployment

Four deployment modes configured:

1. Docker: docker-compose.web.yml (includes PostgreSQL, Nginx)
2. Vercel: vercel.json (serverless functions)
3. Traditional: nginx.conf (reverse proxy, SSL)
4. Desktop: Unchanged Electron build

Browser Support

Docs: 5 guides (847 LOC)

Key: vite.config.web.ts, Dockerfile.web, src/adapters/*, src/server/*, src/web/*

Breaking Changes

None. Desktop Electron app unchanged and fully compatible.

Dependencies Added
