2 |
3 | This is a project set-up using Grunt to take care of some standard tasks such as: compiling AMD based modules using RequireJS, watching/compiling Sass into CSS, watching/linting JS code and some other things such as running unit tests.
4 |
5 | ## Dependencies
6 |
7 | - `gem install image_optim`
8 |
9 | ## Help using Grunt
10 |
11 | - [Grunt Boilerplate](http://www.integralist.co.uk/posts/grunt-boilerplate.html)
12 | - [Using Grunts Config API](http://www.integralist.co.uk/posts/grunt-config.html)
13 |
14 | ## TODO:
15 |
16 | - Look at integrating Jasmine code coverage via `istanbul` plugin
17 | - Write custom task to clean `release` directory after RequireJS has run
18 | - Write custom task to rewrite html to use compiled JS files after successful release build
19 | - Write custom task for renaming un/optimised html files
