Better APIs with GORM and GraphQL

This 3-hour workshop takes a dive deep into a GORM extension and Grails® plugin that combine GORM and GraphQL to increase developer productivity. Through real-time, hands-on exercises, you'll quickly become proficient enough with the technology to bend it to your will.
