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 is Sencha Cmd

Sencha Cmd is a cross-platform command line tool that provides many automated tasks around the full life-cycle of your applications from generating a new project to deploying an application to production.

What does Cmd do?

Cmd perform serveral function. Here are few listed below, there are more, you can refer above link above

  This is most import task in development lifecycle. [ sencha app build {enviroment} ] is one which each Sencha Developers lives by.

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.
