Let’s explore some common use cases for AWS AppSync, where AWS AppSync can help to build GraphQL APIs fast. Simple Data-Centric GraphQL API A typical use-case for AppSync is providing a data-centric API to an existing data source. The advantage
There are two essential concepts for integration today: APIs and events. APIs allow for reading and writing data, calling functionality and starting processes. APIs connect us with actuators in the digital world that enable us to do and change things.

To read data with GraphQL, the client uses the query method. In the pattern of this query, the client has to explicitly specify all the object and fields it is interested in. As a result of the query, the client
Modern clients need to get near real-time updates that get triggered when something changes on the server. For example, an instant messaging app needs to get notified, when a new message arrives on the server, or a weather app needs
