FlowWatch: Python File Watching Solution

DEV Community •
×

Developers building file-processing pipelines often write repetitive boilerplate code to watch directories and react to changes. FlowWatch addresses this by providing a minimal, ergonomic layer on top of the watchfiles library. Created by MichielMe, this open-source tool simplifies file-driven workflows using a decorator-first approach. Instead of manually wiring watchers, users declare the target folder, file patterns, and the handler function.

FlowWatch manages the underlying complexity, including recursive watching, debouncing, and event dispatching. It also supports processing existing files on startup and offers a real-time web dashboard for monitoring. The library includes a CLI powered by Typer and Rich for handler visibility and configuration.

This solution is particularly relevant for broadcast technology and data engineering sectors where media ingest and config reloading are common. It reduces maintenance overhead and improves code readability by separating the 'what' from the 'how' of file watching.
