It doesn’t matter if you are a high level developer or a newbie – Grunt can help you. I will share a few practical ways I use Grunt with. You can do a lot more with Grunt than just those solutions that I will discuss. I will only show only a few of my favorites. Also I am still in the learning process of all of the benefits of Grunt, so if you have a usage that you think is important and is not listed here, please share! All of my current usages for Grunt is for static resources.
Minify your code
With Grunt you can easily minify your code into a destination file. The most common way to minify a file with Grunt is to use Uglify.js. there is a lot of information on the Grunt website on how to get started.
With Grunt you can combine a few files into one file – that is great for configuration files. You probably have different configuration values on your development server than your production server – just make all your configurations on a separate file and combine it with Grunt. The build will be per server.
you can put JSLint as part of the build process, personally I don’t use that feature since I use JSLint directly into my IDE, but that can be useful for other people.
We can integrate our tests with the Grunt build. This is extremely useful since I can integrate the testing process directly to the build process and when the test is failing – I will get an immediate feedback.
Remove all of your debugging code on the build, that way no accidental console.log statements on the real script.
