Express Web Application Development

By: Hage Yaaapa

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.

The default text blocks in Jade work well for simple text segments, but can become problematic for large segments with lots of formatting. That's where text-to-HTML filters such as Markdown excel.

Filters are Jade's way of supporting other text formatters within it. Jade is currently compatible with Stylus, Less, Markdown, CDATA, and CoffeeScript. Filter blocks are marked by a colon, followed by the name of the filter.


Filters for Stylus, Less, Markdown, CDATA, and CoffeeScript, don't work right out of the box; you will need to install their respective packages for the filters to work in your code.

Let's find out how filters work using Markdown as an example.

First, install the markdown Node package by executing the following command:

$ npm install markdown

With the package installed, you will be able to use Markdown in your code. The following is an example of using the Markdown syntax within the Markdown filter in a Jade view:
