How To Use CorrelationId in Node Js Microservices

Correlation IDs provide the standard solution to this problem. A correlation ID uniquely identifies each ‘user requests’, for each user interaction.
Distributed systems, and those using microservices architectures in particular, scatter the order’s log messages further, across multiple locations, to be gathered by centralised logging tools. To make it straightforward to investigate problems, you need a way to group the log messages that relate to a particular order, in all of your systems or services.
