Dependency Management

• Berkshelf

– Similar to npm, cocoapods, or composer

– Created and opensourced by Riot Games

• League of Legends

Bugs (Foodcritic)

• They are hard to track down

• Foodcritic – static analysis of cookbooks

– Doesn’t find everything, similar to jshint

– Give examples of errors it finds

Years

Thanks
