The Ext JS 4 development environment

There are two core components required for Ext JS 4 development as follows:

  • The Sencha Cmd Tool: This is a cross-platform, Java-based, command-line tool that provides many options to help manage the lifecycle of your applications
  • Ext JS 4 SDK (Software Development Kit): This contains all source files, examples, resources, and minified scripts required for application development

We will now examine and install each of these components.

The Sencha Cmd Tool can be downloaded from http://www.sencha.com/products/sencha-cmd/download. The file is approximately 46 MB and needs to be unzipped before running the setup process.
