Pro Express.js is an exhaustive book on one particular library. Unlike Practical Node.js (Apress, 2014) which covered many
libraries, Pro Express.js is focused on the single module Express.js. Of course, where it’s necessary to cover other related
libraries, such as middleware, the book touches on those as well, but not as extensively as on the framework itself.
Pro Express.js covers middleware, the command-line interface and scaffolding, rendering templates, extracting
params from dynamic URLs, parsing payloads and cookies, managing authentication with sessions, error handling,
and prepping apps for production.
Pro Express.js is organized into four distinct parts, the individual chapters of which are set forth in the Table of
Contents:
1. Getting Started: A hands-on, quick-start walkthrough to give you a taste of the framework
2. Deep API Reference: Serves as an Express.js v4.8.1 API reference that you can read in full or
skim through as you need information about certain methods
3. Solving Common and Abstract Problems: The best practices for code organization and
patterns—topics that are good to know when working with Express.js
4. Tutorials and Examples: Tutorials (meticulously depicted coding exercises) and examples
(less detailed explanations of more complex apps) for the real world
