The best way to see how GraphQL operates is with an example.Ībove is an example of a GraphQL schema describing the Todo type, the basic to do structure you’ll use when building RazeList. With this approach, clients only access the data they need and minimize the amount of data sent over the network. Most APIs these days would be considered RESTful however, the REST standard is loosely interpreted so you’ll likely have a different experience across multiple REST APIs.Ĭontrary to REST, GraphQL only exposes a single endpoint which you interact with via queries. REST APIs work by exposing multiple endpoints for applications, each one designed for a specific data type. If you’ve worked with server-side APIs before, you’re likely already familiar with REST. GraphQL was developed by Facebook in 2012 it’s a query language and server-side runtime for executing queries designed to work with server-side APIs. About GraphQL and AppSyncīefore writing any code, you’ll first need to learn what GraphQL is and how it works with AppSync. You’re going to change that, but there are a few prerequisites you need to take care of first. Right now, the project is nothing more than a greeting. It’s your one source of truth for all of your to dos, and more importantly, all of your “dones”! When you’re finished with this tutorial, you’ll always know where you are with your tasks, no matter which device you’re using. RazeList helps your to dos stay in sync across all your iOS devices. Open RazeList.xcodeproj inside the starter folder. The app will work both with and without an internet connection as well! Getting Startedĭownload the project materials using the Download Materials button at the top or bottom of this tutorial. The app will allow you to create, delete and complete to dos while keeping your app’s data synchronized with the AppSync cloud service. You’ll learn all this by implementing a to do list app with SwiftUI.
