A View Into the Vortex, or Tracing Asynchronous Operations in Node

Description

Tracing asynchronous code paths in Node.js is really hard. This makes it difficult to understand what is going wrong when your application blows up. Since Node.js version 4.0, however, Node has included the AsyncWrap API. In this talk you will learn how you can use the API to to gain a better understanding of what went wrong when your application fails, and where potential asynchronous processing bottlenecks are lurking.

Learning objectives

I will be presenting the AsyncWrap API in an overview format, with some discussion of the potential usages of the API in user applications and custom frameworks. I will review some existing modules that provide an abstraction layer over this low-level API, and demonstrate the development of a long stack trace module, making use of the API.
