 # Summary
 
 In this chapter we learned what Express.js is and how it works. We also explored different ways to install it and use its scaffolding (command-line tool) to generate apps. We went through the Blog example with a high-level overview (traditional vs. REST API approaches), and proceeded with creating the project file, folders, and the simple Hello World example, which serves as a foundation for the book's main project: the Blog app. And then lastly, we touched on a few topics such as settings, a typical request process, routes, AJAX versus server side, Pug, templates, and middleware.

+In the next chapter we'll examine an important aspect of modern web development and software engineering: test-driven development. We look at the Mocha module and write some tests for Blog in true TDD/BDD style. In addition, the next chapter deals with adding a database to Blog routes to populate these templates, and shows you how to turn them into working HTML pages!
