Angular projects require automation. Period.
In this series we will take a look at Gulp. Gulp is a task runner. It is the commander of our army of helper robots that take critical, yet totally mundane, tasks and perform them hundreds of times per day so we don't have to. When we sit down to work, we want to enter a single command, and then spend the rest of our day writing code, testing, and basically not thinking about how it is all glued together in the background.
Automation is critical to any project of significant size. We will start with the Eggly Bookmarks application, and develop proper build automation that will include production ready tools that you can start using in your applications today!
I would actually use bower for that.
If you mean how to automatically include them, well there are several ways to do that, actually.
gulp-usmin, gulp-inject, wiredep, all kinds of options, but it depends on your specific goal.
