JARVIS2 is a real-time dashboard framework designed for Raspberry Pi, built with Flask (Python) and Mithril (JavaScript). It features live-updating widgets via server-sent events (SSE) and a plugin-based job system for data fetching. The backend schedules periodic jobs (e.g., weather, public transport, email, RSS) that push data to connected browsers. The frontend renders widgets using Mithril components and updates them reactively as events arrive. The architecture is a monolith: a single Flask application with background scheduling via APScheduler. Key entry points are the Flask routes for dashboards, individual widgets, and the SSE event stream. External dependencies include various APIs (Yr, Entur, Avinor, Google APIs, Sonos, etc.) and libraries (Flask, APScheduler, requests, BeautifulSoup, soco). The codebase is well-structured, with clear separation between job implementations, static assets, and templates. It includes a comprehensive test suite and CI pipeline. The project is actively maintained, targeting Python 3.14 and using modern tooling (uv, ruff). However, it retains some deprecated dependencies (oauth2client) and Python 2 compatibility shims, indicating moderate technical drift.
