Exploring Local-First Applications and Data Synchronization Challenges: Part 1 - JSJ 654

This week on JavaScript Jabber, we’re joined (again!) by Val Karpov — the maintainer of Mongoose — to talk about what’s new in Mongoose 9, how async stack traces are changing the debugging game, and why AI is quietly reshaping the way we build developer tools.

In this episode of JavaScript Jabber, I sat down with Matteo Collina—chair of the Node.js project and founder of Platformatic—for a deep, no-fluff conversation about Node.js performance in the real world. We dug into what actually happens when you run Node at scale, especially with server-side rendering, Kubernetes, and modern frameworks like Next.js.

AI is writing more of our code than ever before—but should we actually trust it? In this episode of JavaScript Jabber, I sat down with Itamar Friedman from Qodo (formerly Quoto) to dig into one of the biggest questions developers are wrestling with right now: What happens when AI is generating code, reviewing code, and shaping how we ship software?
