Understanding Sencha Cmd

If you are coming from other JavaScript framework like AngularJS, you would be perplex with the Sencha Cmd when developing with ExtJS.

If your are new to ExtJS, I would recommend you to check my previous blog about Sencha ExtJS.

What are the software dependencies?

Java Runtime Environment (JRE)
Cmd to produce a valid build, so it’s necessary to have Java installed properly. Sencha Architect requires the JRE to properly utilize Sencha Cmd.

Ruby
Sencha Architect may use Ruby during the app build process when building a theme. Theming in Sencha frameworks may require Sass and Compass depending on the Cmd version used. You don’t need to install these two dependencies since they ship with the versions of Sencha Cmd and Sencha Architect as necessary. However, Sass and Compass run on top of Ruby, so it does need to be specifically installed when using versions of Cmd older than 6.x.
