SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

NuiCpp simplifies the development of C++ user interfaces by providing a domain-specific embedded language that allows developers to build reactive, browser-based UIs directly in C++ without needing to write manual JavaScript or HTML.

Core Features & Use Cases

  • Reactive UI Components: Build complex, state-driven interfaces using Nui::Observed and declarative element syntax.
  • Type-Safe Interop: Seamlessly bridge C++ and JavaScript using Nui::val and automatic type conversion.
  • Use Case: Create a high-performance terminal emulator or a custom dashboard application where the logic and UI are unified in a single C++ codebase, compiled to WebAssembly.

Quick Start

Use the nui-cpp skill to generate a new function component that displays a reactive counter button.

FAQPage Schema
How do I build reactive UI components in C++ for WebAssembly?

You can build reactive UI components in C++ for WebAssembly by using the Nui library's declarative element syntax and Nui::Observed for state management. This allows you to create state-driven browser interfaces without writing manual JavaScript or HTML.

Can I use C++ for frontend web development without writing JavaScript?

Yes, you can use C++ for frontend web development without writing JavaScript by leveraging the Nui library compiled with Emscripten. It provides a domain-specific embedded language to define UI elements directly in C++ that compiles to WebAssembly.

How do I bridge C++ and JavaScript in a WebAssembly application?

You bridge C++ and JavaScript in a WebAssembly application by utilizing Nui::val for type-safe interop and automatic type conversion. This mechanism allows your C++ code to seamlessly interact with JavaScript APIs while maintaining strict type safety.

Does Emscripten support state-driven web dashboards written entirely in C++?

Emscripten supports state-driven web dashboards written entirely in C++ when paired with the Nui library. You can unify your application logic and UI in a single C++ codebase, using reactive state management to handle complex interface updates.

What is the best way to manage state in a C++ WebAssembly UI?

The best way to manage state in a C++ WebAssembly UI is by using Nui::Observed to track reactive state variables. This approach automatically triggers declarative UI updates and reactive side-effects whenever the underlying state values change.

Why do I need strict syntax rules for element rendering in C++ WebAssembly?

Strict syntax rules for element rendering in C++ WebAssembly are required to ensure the Nui library correctly parses declarative UI components and manages reactive side-effects. Adhering to these rules guarantees proper event handling and state synchronization.
