Syntax - Tasty Web Development Treats

Scott and Wes are joined by Phil Miller and Theo Ephraim to talk about Varlock, a new approach to environment variables that adds schemas, validation, and security to the humble .env file. They dig into the risks of traditional env workflows, how schema-driven configs improve DX, and how tools like Varlock help manage secrets safely across frameworks, CI, and AI-powered workflows.
