Micro-logging NPM

Logging

Simple logging module for microsystems that wraps winston and continuation-local-storage.

What we ultimately wanted to achieve is to generate microservice logs that are unique, traceable, and contain enough data to act on quickly and effectively. To create these logs: Append a unique identifier to requests as they enter the architecture. Identify the service that generates events. Generate events specific to each microservice as the request enters and leaves the service. Correlate events from each microservice to create an overall view of the request.

Install

 npm install micro-logging
