AppKits

AppKits is a cross-platform application development framework designed to enable building software for desktop, mobile, and web environments from a single codebase. It provides a modular architecture, a comprehensive UI toolkit, a data layer, and platform adapters that translate framework abstractions into native APIs.

The core runtime handles lifecycle, state management, and dependency injection. The UI toolkit offers declarative components, theming, accessibility, and responsive layouts. The data layer supports local storage, synchronization, and offline caching, while the networking stack abstracts HTTP requests and event emissions.

AppKits is organized into modules such as Core, UI, Data, Networking, Persistence, Extensions, and Tooling. It uses a plugin system to allow third-party adapters for different platforms and services. The framework emphasizes performance, tree-shaking, and extensibility.

Platform support is achieved through adapters that map framework constructs to native APIs. Target environments commonly include Windows, macOS, Linux, iOS, Android, and modern web browsers. The project provides a command-line interface, templates, and a package manager for managing dependencies and project scaffolding.

AppKits is maintained as an open-source project with a community of contributors. Documentation covers getting started, architecture, and best practices. Adoption typically focuses on teams seeking code reuse across platforms, with trade-offs including an initial learning curve and potential runtime overhead compared to native implementations.
