A simple Ext.js project with a full Grunt build showing concat, testing, code coverage

You need the following installed:

• node.js
• grunt-cli - with node installed run npm install -g grunt-cli

Run:

$ git clone git://github.com/mattgoldspink/grunt-extjs-example.git
$ cd grunt-extjs-example
$ npm install
$ grunt

To view it in your browser quickly I'd recommend installing the servedir npm module:

$ npm install -g servedir
$ servedir .
Serving /Users/matt_goldspink/development/grunt-extjs-example/ on http://localhost:8000

You should then be able to see the development version on

http://localhost:8000/www/

and the built version on

http://localhost:8000/build/www/

You can also see Code Coverage reports on

http://localhost:8000/build/reports/lcov-report/index.html

And a Plato code complexity report on

http://localhost:8000/build/reports/plato/index.html

At the moment the grunt file runs the following tasks:

• JSHint - for code validation and to enforce a coding standard
• Clean - to clean out the build directory before building into it
• Sencha_Jasmine - Runs any Jasmine tests and sets up the Ext framework to work nicely in it
• Sencha_Dependencies - Calculates the dependencies that your project uses in the correct order for them to work when concatenated
• Uglify.js - Concatenate, minify and generate Source Maps so you can debug the minified code against the original source code
• Copy - Copy over additional required files (CSS, images, extra JS files) and also the index.html which we'll process to inject our concatenated JS file
• Istanbul - When the tests are run we also generate code coverage and output an html report in build/reports/lcov
• Plato - Generates code complexity reports

There's more tasks that I'll likely add over time. At my current company we also use the following Grunt tasks:

• JSDuck - Generate documentation for all the files
• Compass - Compile our Compass style sheets
