HMR for Python [![PyPI - Version][pypi-version-badge]][pypi] [![PyPI - Downloads][pypi-downloads-badge]][pepy] [![Python Versions][python-versions-badge]][pyproject] [![PyPI - Status][pypi-status-badge]][repo] [![GitHub Created At][github-created-badge]][repo] [![GitHub commit activity][github-commits-badge]][commits-history] HMR provides a pythonic, flexible, progressive-yet-intuitive reactive programming engine / framework, and on top of that, a fine-grained, on-demand hot-reload tool. In Python, HMR stands for Hot Module Reload, though in JavaScript it commonly refers to [Hot Module Replacement][webpack-concepts-docs]—essentially the same concept. It is a feature that allows part of your app to be updated at runtime without a full rerun, without needing to restart the entire process. Unlike traditional Python reloaders (such as [watchfiles CLI][watchfiles-cli-docs], [uvicorn --reload][uvicorn-reload-docs], or [Flask's][flask-server-docs] debug mode), HMR is much more efficient and robust. These tools typically restart the entire process whenever a file changes, which is wasteful. HMR instead intelligently reruns only what's necessary, keeping your app state intact.
