About this project
A Python → React widgets framework for Apache Airflow 3.1 that lets you attach rich, contextual UI panels to Airflow pages (e.g., task instance views).
The core idea: write widgets in Python (per DAG / per task), serve them via a small FastAPI plugin endpoint, and render them in the Airflow UI using a React panel.
This project currently focuses on being:
Simple to author: “just return a list of widget specs”
Fast in the UI: widgets are computed at page-load time → keep them lightweight
Extensible: add new widget types on the React side without changing Airflow internals
What it supports today
Widget types
Markdown: runbooks, descriptions, links, snippets
Tables: key/value blocks, metrics tables, column dictionaries
Mermaid diagrams (via Markdown): lineage/flow diagrams rendered by your Markdown renderer (must support ```mermaid)
Where widgets can appear
Task Instance views (recommended first target; easiest mental model)
Can be extended to DAG, TaskGroup, Run pages depending on Airflow’s react_apps.destination support in your version.
