Nextcloud News is an RSS/Atom feed reader app for Nextcloud. It provides a PHP backend (MVC with controllers, services, DB mappers) and a Vue 3 + TypeScript frontend. Users can subscribe to feeds, organize them into folders, read articles with read/unread/starred states, apply keyword filters, import/export OPML, and sync with mobile/desktop clients via REST APIs. Background cron jobs handle feed updates and cleanup. The architecture follows Nextcloud's app framework with scoped dependencies to avoid conflicts. Key entry points include the web UI (Vue SPA), CLI commands (`occ news:*`), and API endpoints (v1-2, v1-3, v2). External dependencies include feed-io for parsing, Guzzle/PSR-18 for HTTP, and Readability.php for full-text extraction. The codebase is well-tested with unit, integration, and BATS tests, and uses modern tooling (Vite, PHP 8.2+).
