Overview of this book

The MERN stack is a collection of great tools—MongoDB, Express.js, React, and Node—that provide a strong base for a developer to build easily maintainable web applications. With each of them a JavaScript or JavaScript-based technology, having a shared programming language means it takes less time to develop web applications. This book focuses on providing key tasks that can help you get started, learn, understand, and build full-stack web applications. It walks you through the process of installing all the requirements and project setup to build client-side React web applications, managing synchronous and asynchronous data flows with Redux, and building real-time web applications with Socket.IO, RESTful APIs, and other concepts. This book gives you practical and clear hands-on experience so you can begin building a full-stack MERN web application. Quick Start Guides are focused, shorter titles that provide a faster paced introduction to a technology. They are for people who don't need all the detail at this point in their learning curve. The presentation has been streamlined to concentrate on the things you really need to know.

Using an HTTP request logger

As previously seen, writing a request logger is simple. However, writing our own could take precious time. Luckily, there are several other alternatives out there. For example, a very popular HTTP request logger widely used is morgan

morgan is a configurable middleware function that takes two arguments format and options which are used to specify the format in which the logs are displayed and what kind of information needs to be displayed.

There are several predefined formats:

  • tiny: Minimal output
  • short: Same as tiny, including remote IP address
  • common: Standard Apache log output
  • combined: Standard Apache combined log output
  • dev: Displays the same information as the tiny format does. However, the response statuses are colored.
