+Martijn Walraven is a developer on the Apollo Open Source team at Meteor, where he focuses on bringing GraphQL to mobile developers. He created a strongly typed GraphQL client for iOS written in Swift, and is working on doing the same for Android. He'll briefly introduce GraphQL and how it is a product-developer-friendly and efficient method for fetching structured data from a server, designed to be an alternative to REST. In this talk, he’ll explain why GraphQL was developed, how it works, and how you can use it in your own apps, whether you are a React (Native), Angular, or native iOS or Android developer.
