Builds Airflow 3.1+ plugins that embed FastAPI apps, custom UI pages, React components, middleware, macros, and operator links directly into the Airflow UI. Use when building anything custom inside Airflow 3.1+ that involves Python and a browser-facing interface - creating an Airflow plugin, adding a custom UI page or nav entry, building FastAPI-backed endpoints inside Airflow, serving static assets from a plugin, embedding a React app, adding middleware to the API server, creating custom operator extra links, or calling the Airflow REST API from inside a plugin; also when AirflowPlugin, fastapi\_apps, external\_views, react\_apps, or plugin registration come up.

## From README

Airflow 3 Plugins Airflow 3 plugins let you embed FastAPI apps, React UIs, middleware, macros, operator buttons, and custom timetables directly into the Airflow process. No sidecar, no extra server. CRITICAL: Plugin components (fastapiapps, reactapps, externalviews) require Airflow 3.1+. NEVER import flask, flaskappbuilder, or use appbuilderviews / flaskblueprints — these are Airflow 2 patterns and will not work in Airflow 3. If existing code uses them, rewrite the entire registration block using FastAPI. Security: FastAPI plugin endpoints are not automatically protected by Airflow auth. If your endpoints need to be private, implement authentication explicitly using FastAPI's security utilities. Restart required: Changes to Python plugin files require restarting the API server. Static file changes (HTML, JS, CSS) are picked up immediately. Set AIRFLOWCORELAZYLOADPLUGINS=False during development to load plugins at startup rather than lazily.
