We just launched Lumina as open source. LLMs fail silently, and it’s hard to understand what’s happening once they’re in production. Lumina helps teams observe and debug LLM behavior with real traces and signals. OSS SDK is live 👇 npmjs.com/package/@uselumina… Feedback welcome.

I Replaced Lodash With 20 Lines of Vanilla JS (And Cut 72KB From My Bundle)

Why importing _.debounce cost me more than I thought — and how native JavaScript made it irrelevant

Building LLM apps taught us one thing: When things go wrong, you usually don’t notice until users complain. We built Lumina to change that — now open source. npmjs.com/package/@uselumina…

I Replaced Axios With 25 Lines of Vanilla JS (And You Should Too)

Stop importing 13KB for features JavaScript already has. Here’s what Axios actually does (and how to do it yourself).
