Sass is a new way of writing CSS. It is possible to use variables and define functions and mixins. It is an alternative to Less maybe you have worked with Less or heard about it—Sass is very similar. After downloading and installing Ruby, please install Sass as well. Compass is a Sass framework and is also required.
Sass and Compass are the heart of the Ext JS theming engine. We can check whether we have the correct environment by executing the following commands in a terminal application:. Note that the Ruby version installed is 2. The last step is a web server. The simplest one that we can use to execute the examples of this book is Apache Xampp.
All the software required to set up the environment mentioned in this book is available for Linux, Windows, and Mac OS. Now that we have our environment configured, we can download Ext JS. Ext JS has some different license flavors: commercial and open source. For this book, we are going to use the open source one. Sencha Cmd is responsible for creating the application and making, building, and compiling Sass and Compass to generate the application's CSS.
After the installation of Sencha Cmd, the sencha command will be available from the terminal application as well. Once we start the Apache server, we will be able to execute the Ext JS examples from our local environment:. While developing with Ext JS, we will consult the documentation a lot. Whenever we mention the name of an Ext JS component in this book, it is recommended that you go to the documentation and take a look at it. It contains guides it is also highly recommended that you spend some time reading the guides before diving into this book since the guides provide basic knowledge about the framework , and links to blog posts and also to the documentation itself.
As we will consult it a lot, we recommend installing the documentation locally as well. Unzip the docs inside the Xampp htdocs folder as well and access your localhost , as shown in the following screenshot:.
There is also Sencha Architect which also has the autocompleting feature. Feel free to use the editor or IDE you are most comfortable with to develop the source code of this book! In this chapter, we quickly overviewed Ext JS and provided some references that are useful to read to gather the basic knowledge required to understand the terms and components we will be using in this book.
