Enabling debug logs

More than 13,450 modules directly depend on the third-party debug module (at the time of writing). Many other modules indirectly use the debug module by the use of those 13,450. Some highly notable libraries, such as Express, Koa, and Socket.io, also use the debug module.

In many code bases, there's a wealth of often untapped tracing and debugging logs that we can use to infer and understand how our application is behaving.

In this recipe, we'll discover how to enable and effectively analyze these log messages.
