Show HN: Reaktiv – I built Excel-like reactive programming for Python

https://bui.app/when-frontend-reactivity-meets-backend-python-the-story-of-my-first-1-000-download-library/
2•buibuibui•1y ago
Hi HN! I created Reaktiv, a Python library bringing reactive programming to the backend world that recently hit 1,000+ monthly downloads.

I'm actively promoting it because I believe signal-based reactivity (a concept that spread rapidly in frontend development) has huge untapped potential in Python. My breakthrough came when I stopped describing it as "Angular signals for Python" and started calling it "Excel-like computation graphs" - suddenly Python developers understood the value.

The library automatically tracks dependencies between computations, only recalculating values when dependencies change. This eliminates manual dependency tracking, prevents synchronization bugs, and reduces cognitive load when managing complex state.

Interestingly, I've noticed some initial interest from data scientists, though I'm still exploring what specific problems it might solve for them. I also believe the Home Assistant/IoT communities could benefit greatly from this approach.

Would love your thoughts on bringing frontend patterns to backend development!
