Q2: What is GraphQL and how does it work?

GraphQL is a query language developed by Facebook that provides an alternative to REST APIs. It is designed to address common issues such as the need for multiple endpoints, under-fetching and over-fetching of data, and versioning. GraphQL provides a unified interface that simplifies the process of retrieving data from the backend, allowing front-end developers to access all the data they need from a single endpoint.

Q3: What happens after a GraphQL service is running?

Once a GraphQL service is up and running, it can receive and process GraphQL queries. The service will first validate the query to make sure it only refers to the types and fields that have been defined. Once the query is validated, the service will execute the provided functions to generate a response. To learn more about GraphQL services, click Continue Reading.

Q4: Can a GraphQL query cause a data write?

GraphQL is similar - technically any query could be implemented to cause a data write. However, it is useful to establish a convention that any operations that cause writes should be sent explicitly via a mutation. Just like in queries, if the mutation field returns an object type, one can ask for nested fields.

Q5: What are MP GraphQL APIs?

Applications coded to the MP GraphQL APIs are portable and can be deployed into Java server runtimes such as Open Liberty, Quarkus, Helidon, and Wildfly. This allows applications to utilize other Jakarta and MicroProfile technologies.
