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.

Comments


Comments in Jade are marked using double slashes (//) or double slashes with a trailing hyphen (//-). The former comments show up in the HTML as HTML comments, while the latter remain in the view file and are not rendered in the HTML.

Tags nested within a comment will either be commented in the HTML or not be rendered at all, depending on the comment type.

Here are some examples to help you understand how comments work in Jade:

Jade

HTML

// Here is a comment
p Howdy?

<!-- Here is a comment-->
<p>Howdy?</p>

//- This comment will not be shown in the HTML
p Something interesting

<p>Something interesting</p>

//
  p This paragraph will be commented out

<!-- <p>This paragraph will be commented out</p> -->

//-
  p This paragraph won't even show up in the HTML

 

Jade even supports Internet Explorer's conditional comments:

// if lt 8
  script
    alert('Upgrade your browser!');

will render:

<!--[if lt 8]>
    <script...
