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.
