Ahnfelt/react4s

This repository contains the React4s library, a Scala.js framework for building reactive user interfaces. It provides core abstractions for managing state and rendering components to the DOM, along with utilities for handling events and CSS. The system supports cross-compilation for Scala 2.12 and 2.13 and is published to Sonatype Central.

The \Component.scala\, \Main.scala\, and \ReactBridge.scala\ files in \src/main/scala/dk/ahnfelt/react4s\ have been deleted. This removes the library's core component abstraction, the example application entry point, and the JavaScript bridge that rendered Scala components to the DOM. Users relying on this specific version of the react4s library will lose access to these foundational classes and utilities.

This release updates the library to support Scala 2.13 and introduces several behavioral changes to the core API. The package has been moved from \dk.ahnfelt.react4s\ to \com.github.ahnfelt.react4s\. State initialization now supports dynamic values via \State.of\, allowing initial state to be based on props. The \Signal\ type replaces the previous \Get =\> T\ pattern for reactive values. Component rendering now returns \Node\ instead of \ElementOrComponent\, and the \Get\ instance is renamed to \Get.Unsafe\ to clarify its usage. Additionally, new CSS pseudo-classes (e.g., \disabled\, \evenChild\) and event handlers (e.g., \onSubmit\, drag/drop events) are added, and the \Loader\ attachable now handles race conditions more robustly.

The project has been upgraded to Scala 2.13.18 as the primary version, with cross-compilation support added for Scala 2.12.19. The build manifest now includes comprehensive metadata (organization, description, licenses, SCM info, developers) and configures publishing to Sonatype Central. Additionally, the Scala.js linker is configured to relativize source map bases, and the compiler option for the 'feature' package is enabled.

The repository is initialized with core project files, including a new .gitignore to exclude build artifacts (target/, .idea/, .bsp/) and generated HTML, a LICENSE.txt establishing the MIT license, and a comprehensive README.md that documents the React4s library's API, usage examples, and design principles. Additionally, the previous index.html demo file has been removed.
