⛔️ 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.
