A Few Practical Notes on GraphQL

Points Worth Knowing

• A GraphQL schema defines a precise contract between client and server: exactly what data is available and how it's shaped.
• Tools like GraphiQL let developers interactively explore and test an API's schema.
• GraphQL subscriptions enable real-time data, like live chat messages, delivered over a WebSocket connection.

Takeaway

None of these points are complicated on their own, but knowing them can lead to better technical decisions about GraphQL on your next project.
