Welcome to the official wiki for eQuantic.UI, a C# framework for ultra-fast interface development: components are written once in C# and realized as DOM + CSS on the web (via TypeScript compilation and Intelligent Reconciliation) and as GPU pixels on native (via the proprietary Photon engine — Metal/Vulkan, no WebView, no Skia).
- Write-Once Components - THE architecture: one vocabulary, two realizers — the same class on web and native.
- Photon Engine - The native GPU engine: normative SDF core, real text/icons (CoreText/CoreGraphics), Metal + Vulkan backends, the macOS/iOS/Android shells.
- Design System - Typed tokens, the ATOMIC style engine (styling without CSS), IAppTheme/Material 3 theming, density and the dense type rungs.
- Code Editor - The editor MODEL an IDE is built on: line documents, incremental highlighting for six languages, undo that thinks in words, and the controller behind every editing command.
- Architecture Overview - DDD, CQRS, and the Clean Architecture philosophy in the UI.
- Package Architecture - Self-contained package design and artifact management.
- Components - The component catalog: actions, surfaces, navigation, overlays, the recycling ListView, the Spreadsheet grid.
- Styling - Typed C# styling: one engine, atomic CSS on the web, GPU paint on native — plus the low-level HTML escape hatch.
- Compiler (CSharpToJs) - How we convert C# into performant TypeScript.
- Compile-Time Evaluation - Zero-overhead abstractions with symbolic compilation.
- Supported C# Features - Detailed matrix of supported language features and APIs.
- External Type Resolution - How the compiler resolves classes defined in external files.
- Build Flow - How the compilation pipeline works with zero external dependencies.
- Runtime (TypeScript) - Details on the reconciler, state management, and component lifecycle.
- Performance & Optimization - Keyed Diffing, WeakMap Listener tracking, and other optimizations.
-
Server Integration -
AddUI(),UIOptions, middleware, SSR, and SEO configuration. -
Asset Management -
IRequireAssets,IComponentAssetProvider<T>, and automatic asset injection. -
BunPackage - Declare npm packages directly in
.csproj(zeropackage.json). - Security & Server Actions - Authorization, payload validation, and server action protection.
- Image Optimization - Next.js-style server-side image optimization (resize, WebP, caching).
- Charts - Chart.js and ApexCharts integration.
- Icons - Lucide, Tabler, Heroicons, and more.
- Debugging & Development Tools - Professional debugging with logger and error overlay.
- Project Roadmap - What's ahead.
