10. Short Summary • GraphQL is an APIs just like RESTful. • Ask for what you want. • Use only POST to send data. • Get Predictable Results. @womenwhocode #WWCode
11. GraphQL Server @womenwhocode #WWCode

16. GraphQL is a query language for APIs and a runtime for fulfilling those queries with your existing data. GraphQL provides a complete and understandable description of the data in your API, gives clients the power to ask for exactly what they need and nothing more, makes it easier to evolve APIs over time, and enables powerful developer tools. - - graphql.org @womenwhocode #WWCode
