How to Kill Dependency Conflicts & Tame AI Agents using "Environment-as-Code"?

⛔️ Stop fighting dependency conflicts. ☑️ Learn to treat your local development environment exactly like production infrastructure — as code. This is a demo-packed session, where Google engineers Alex Astrum and James O'Reilly reveal a blueprint for scalable JavaScript development that kills the "works on my machine (but breaks elsewhere)" excuse forever. Discover: 💫 how to use Environment-as-Code (Nix) for zero-config onboarding, 💫 and how to force AI agents to generate secure, type-safe code using semantic rules. 📌 Follow the link to watch the full version of all the conference talks, QnA’s with speakers and hands-on workshop recordings: 🔗 https://gitnation.com/events/jsnation-us-2025?utm_source=youtube&utm_medium=AlexAstrum-JamesOReillyTalk 🔥Want to hear talks like this live?
