Kea is a state management library for React applications that builds on Redux to reduce boilerplate while maintaining flexibility. It features a lazy-loading logic system where logic (actions, reducers, selectors) is only built and mounted when needed. The library provides a plugin system for extending functionality, sophisticated listener handling with breakpoint support for asynchronous flows, and React hooks for accessing state and actions in components. Kea's architecture centers around a context-based system that manages logic instances, their dependencies, and their connection to the Redux store.
This repository is a Spotify client web application that helps users track new releases from artists they follow. It provides a progressive web app (PWA) experience with offline support, allowing users to view, filter, and favorite releases grouped by date. Users can export their release list to CSV or create/update a Spotify playlist with selected tracks. The application handles Spotify authentication via OAuth 2.0 PKCE flow, fetches data from the Spotify Web API, and persists state locally using localForage. Built with React, Redux Toolkit for state management, and Redux Saga for side effects, the app features a modular architecture with reusable UI components, filtering system, and settings management.
