japgolly/scalajs-react

This is a Scala.js library that provides a functional, type-safe interface for building React applications. It manages the React component lifecycle, virtual DOM rendering, and state management, while offering deep integration with functional programming ecosystems like Cats and Monocle. The system also includes comprehensive tooling for testing, documentation, and reproducible development environments.

This period focused on modernizing the project's build infrastructure and establishing a comprehensive downstream testing suite. Key changes included introducing Nix for reproducible development, restructuring the SBT build configuration, and creating a dedicated downstream-tests module to validate the library's behavior across different environments and React versions.

The codebase underwent a major architectural shift to support React 18 and 19, introducing new hooks, root APIs, and component lifecycle methods. This period also saw the introduction of first-class support for Cats/Cats Effect, Monocle, and Scala 3, alongside a significant reorganization of the library's module structure and testing utilities.
