Overview of this book

Express is a minimal and flexible node.js web application framework, providing a robust set of features for building single and multi-page, and hybrid web applications. It provides a thin layer of features fundamental to any web application, without obscuring features that developers know and love in node.js. "Express Web Application Development" is a comprehensive guide for those looking to learn how to use the Express web framework for web application development. Starting with the initial setup of the Express web framework, "Express Web Application Development" helps you to understand the fundamentals of the framework. By the end of "Express Web Application Development", you will have acquired enough knowledge and skills to create production-ready Express apps. All of this is made possible by the incremental introduction of more advanced topics, starting from the very essentials. On the way to mastering Express for application development, we teach you the more advanced topics such as routes, views, middleware, forms, sessions, cookies and various other aspects of configuring an Express application. Jade; the recommended HTML template engine, and Stylus; the CSS pre-processor for Express, are covered in detail. Last, but definitely not least, Express Web Application Development also covers practices and setups that are required to make Express apps production-ready.

To include a file in a view, use the include directive and pass it the path of the file to be included. It is very important to give the correct extension to the include files, because Jade uses the extension of the file to render the content accordingly.


A Jade view file and its included Jade files share the same scope. So variables defined in one file are available to the other.

The indented hierarchy is applicable to the include directive too, so the way you indent it is important.

Let's create an example to understand how include works. In the views directory of your app, create a new directory named includes, where we will be creating the following include files:
