How does Windows.fast modernize Windows desktop application development?

Windows.fast enables building modern Windows applications using web technologies (HTML, CSS, JavaScript) or .NET with WinUI 3. It combines web development speed with native Windows capabilities - system integration, offline functionality, and desktop performance. Build Windows apps as easily as web apps while accessing platform-specific features.

What Windows APIs and features does Windows.fast expose?

Windows.fast provides access to file system, notifications, system tray, Windows Hello authentication, context menus, protocol handlers, and hardware integration. It wraps complex Windows APIs in simple, modern interfaces. Applications integrate deeply with Windows, feeling native rather than like web apps in a wrapper. Full platform capabilities without Win32 complexity.

How does Windows.fast handle application distribution?

Windows.fast packages applications for Microsoft Store, creates installers (MSI/EXE), and provides auto-update capabilities. It handles code signing, crash reporting, and analytics automatically. Distribute through the Store for discoverability or as standalone installers for enterprise deployment. Automated builds create release-ready packages from your code.

Can Windows.fast applications work offline?

Yes, Windows.fast enables full offline functionality with local data storage, background sync, and offline-first architecture. Applications work without internet connectivity, syncing when online. Local databases, file caching, and background tasks ensure productivity regardless of connectivity. Perfect for field workers, travelers, and unstable network environments.

How does Windows.fast compare to Electron for desktop development?

Windows.fast produces smaller, faster applications optimized specifically for Windows. Unlike Electron's large bundle sizes (100+MB), Windows.fast applications are 10-20MB. They use native Windows controls, integrate better with the OS, and consume less memory. Electron offers cross-platform support; Windows.fast offers superior Windows-native performance and integration.

Windows.fast - Native Windows Desktop Apps

The Problem We're Solving

Desktop development complexity

❌ The Old Way (Native Desktop Dev)

• Learn C#, .NET, WPF, UWP-months of training before building first app
• Platform-specific code means separate codebases for Windows, Mac, Linux
• Complex build pipelines, code signing certificates, installer packaging nightmares
• Auto-update systems require custom infrastructure and security considerations
• Distribution through Microsoft Store requires Windows-specific expertise and lengthy approval

✅ The Windows.fast Way

• Use HTML, CSS, JavaScript-web developers build desktop apps with existing skills
• Write once, package for Windows, Mac, Linux-90% code reuse across platforms
• One-click packaging to native executable-Electron/Tauri handles compilation
• Built-in auto-update system-users always get latest version automatically
• Microsoft Store deployment automated-publish directly from CI/CD pipeline

How It Works

Web to native transformation

Build with Web Tech

Team productivity maximized from day one.

Write Once, Deploy Everywhere

Single codebase for Windows, Mac, Linux. 90% code reuse across platforms. Maintain one project instead of three. Features ship to all platforms simultaneously. Bug fixes applied universally. Platform-specific code only where truly needed. Cross-platform becomes default, not aspiration. Maximum reach with minimum effort.

Modern Development Experience

Hot reload during development-see changes instantly. Chrome DevTools for debugging. npm ecosystem with millions of packages. Use modern frameworks like React, Vue, Svelte. TypeScript support built-in. Familiar build tools (Vite, Webpack). Development workflow identical to web apps. Desktop development feels like web development.

Ship Faster

MVP to production in weeks, not months. No native SDK learning curve. Rapid iteration with familiar tools. Deploy updates automatically to all users. CI/CD pipelines with GitHub Actions. Microsoft Store publishing automated. Time to market reduced by 60-80%. Speed becomes competitive advantage. Move faster than native competitors.

Desktop Development Best Practices

Build professional Windows applications

Optimize Bundle Size

Keep installer size small-users abandon 500MB downloads. Tree-shake unused code. Lazy load non-critical modules. Use native modules sparingly-they increase size. Compression and minification in production builds. Aim for under 100MB installers. Fast downloads mean more installs. Delta updates reduce update size to under 10MB.

Implement Auto-Updates

Never ask users to manually update. Silent background updates keep everyone current. Check for updates on launch. Download in background, install on next restart. Rollback capability if update fails. GitHub Releases for distribution. Code signing prevents security warnings. Auto-updates ensure bug fixes reach all users. Zero-touch update experience.

Handle Offline Gracefully

Desktop apps must work offline. Local database (SQLite, LevelDB) for data persistence. Queue network requests when offline, sync when online. Cache API responses. Don't show "no internet" errors-degrade gracefully. IndexedDB for web content cache. Offline-first architecture. Desktop users expect apps to work anywhere, not just online.

Use Native UI Patterns

Match Windows design language-native context menus, standard keyboard shortcuts (Ctrl+S, Ctrl+Z), proper window controls. System tray icon for background apps. Native file dialogs, not custom HTML. Taskbar integration, jump lists. Respect Windows accessibility features. Feel native, not like embedded browser. Users notice when apps don't follow OS conventions.

Secure by Default

Enable context isolation in Electron-prevents XSS attacks. Disable nodeIntegration in renderer. Use preload scripts for IPC. Validate all user input. Encrypt sensitive data at rest. Code signing prevents tampering. CSP headers even in desktop apps. Review dependencies for vulnerabilities. Desktop apps have more privileges-security critical. One vulnerability exposes user's entire system.

Monitor Performance

Desktop apps must feel instant-200ms response time maximum. Profile with Chrome DevTools. Optimize startup time-users abandon slow-loading apps. Virtual scrolling for large lists. Web Workers for heavy computation. Measure memory usage-memory leaks visible in desktop apps. Frame rate monitoring-aim for 60fps. Performance = retention. Slow apps get uninstalled.
