System Architecture

Layered architecture design for maximum security and modularity

Frontend Layer

Pure browser-based implementation using modern web standards. No plugins, extensions, or native code required.

// Core architecture
interface WebOSArchitecture {
  ui: {
    framework: 'React 18+',
    styling: 'Tailwind CSS',
    state: 'Context API',
    routing: 'Next.js App Router'
  },
  runtime: {
    engine: 'V8 JavaScript Engine',
    workers: 'Web Workers',
    storage: 'IndexedDB + LocalStorage',
    crypto: 'Web Crypto API'
  },
  security: {
    isolation: 'Browser Sandbox',
    encryption: 'AES-256-GCM',
    keyDerivation: 'PBKDF2',
    authentication: 'Zero-Knowledge Proof'
  }
}

Advantages

No installation required
Cross-platform compatibility
Automatic security updates via browser
Hardware acceleration support

Limitations

Browser API limitations
Memory constraints
No direct hardware access

Application Layer

Modular application system with sandboxed execution environments.

// Application interface
export interface Application {
  id: string
  name: string
  version: string
  permissions: Permission[]
  
  // Lifecycle hooks
  onMount(context: AppContext): void
  onUnmount(): void
  onMessage(msg: Message): void
  
  // Sandboxed execution
  sandbox: {
    memory: MemoryLimit
    cpu: CPUQuota
    storage: StorageQuota
    network: NetworkPolicy
  }
}

Advantages

Complete application isolation
Resource limit enforcement
Permission-based access control
Hot module replacement

Service Layer

Core services providing OS-level functionality to applications.

// Service architecture
class ServiceRegistry {
  private services = new Map<string, Service>()
  
  register(service: Service): void {
    // Validate service permissions
    this.validatePermissions(service)
    
    // Initialize service worker if needed
    if (service.requiresWorker) {
      this.initializeWorker(service)
    }
    
    this.services.set(service.id, service)
  }
  
  // Inter-service communication
  async call(serviceId: string, method: string, ...args: any[]) {
    const service = this.services.get(serviceId)
    if (!service) throw new ServiceNotFoundError()
    
    // Check caller permissions
    await this.checkPermissions(serviceId, method)
    
    return service[method](...args)
  }
}
