I’ll walk you through setting up a simple Express server, installing Morgan, using different logging formats like dev, tiny, and combined, and even show how to create custom logging styles and log to a file.
This tutorial is beginner-friendly and includes a full live coding demonstration, Postman setup, and examples of real-world scenarios where Morgan is useful.
