Watchfiles – Lightning Fast File Watching in Python 2026
Watchfiles is Rust-powered and much faster than watchdog.
Real Example: Auto-process New Files
from watchfiles import watch
from pathlib import Path
for changes in watch("/data/incoming"):
for change, path in changes:
if Path(path).suffix == ".csv":
print(f"New file detected: {path}")
# process_file(path)
Conclusion
Watchfiles + Rich is the perfect combo for real-time automation.
