About this skill
Production-tested patterns for Flask with the application factory pattern, Blueprints, and Flask-SQLAlchemy. Latest Versions (verified January 2026): Run: uv run flask --app app run --debug This skill prevents 9 documented issues: Error : KeyError in teardown functions when using stream_with_context Source : GitHub Issue #5804 Why It Happens : Flask 3.1.2 introduced a regression where stream_with_context triggers teardown_request() calls multiple times before response generation completes. If teardown callbacks use g.pop(key) without a default, they fail on the second call. Prevention : Status : Will be fixed in Flask 3.2.0 as side effect of PR #5812. Until then, ensure all teardown callbacks are idempotent. Error : RuntimeError when handling concurrent async requests with gevent Source : GitHub Issue #5881 Why It Happens : Asgiref fails when gevent monkey-patching is active. Asyncio expects a single event loop per OS thread, but gevent's monkey-patching makes threading.Thread create greenlets instead of real threads, causing both loops to run on the same physical thread and block each other. Prevention : Choose either async (with asyncio/uvloop) OR gevent, not both.
