Step 5 - Node.JS Logging Overview
Node.js is an open-source server-side platform built using JavaScript & was developed in 2009 by Ryan Dahl. As Node.js uses an event-driven, I/O model it is highly suited to powering real-time applications including live chat & chatbots, automatically refreshing feeds for social media, and additionally, it is increasingly used for sending web push notifications. It is most commonly run on Linux & Windows operating systems.
Winston is the most popular logging library for Node.js as it makes logging more flexible & can be configured to multiple levels.
Winston is well known for its robust feature set & easy installation which we have detailed in this configuration guide. Morgan is commonly used in association with Winston and operates as an HTTP request logger middleware for Node.js.
Parsing, transforming & analysing emergency, critical & error Node.js logs can be hard to perform at scale from the default logging format. Priority messages can easily get lost in the noise of other logging formats (such as Info & Notice) and are not alerted on to be resolved by your wider DevOps team.
Logit.io provides a complete Node.js log analyser by default as part of our log management platform, this includes alerting, collection & visualisations enhancing your text logs to provide data-driven insights & real-time log tailing.
