Express Web Application Development

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.

Generating HTML tags

HTML tags are created by the mere mention of their names in the view file. If you would like to include any text within a tag, include it right after the tag name.

div Hello World!

<div>Hello World!</div>





span Howdy?


It is important to note that it is your responsibility to use valid HTML tag names, Jade will just create an element—valid or not.

Hierarchy of HTML elements

In HTML, we create hierarchical DOM elements by nesting elements within other elements with the use of opening and closing tags. In Jade, we create hierarchy by the use of indentations—a tag indented below a tag is hierarchically placed under the former tag.


You can use either tabs or spaces for indentation. Whichever you choose...
