From Server to Serverless - A Debugger's Point of View

Explore the transition from server-based to serverless architectures in this 24-minute conference talk from the Cloud Native Computing Foundation (CNCF). Dive into the challenges faced by developers when debugging serverless applications and discover innovative solutions. Learn about the role of transpilers, the importance of source maps, and techniques for efficient source map loading. Gain insights into working with V8, implementing lazy loading, and parsing source maps for effective trace mapping. Understand how these debugging strategies apply beyond serverless environments and walk away with valuable lessons for modern cloud-native development.
