GraphQL makes it easy for clients to fetch data from servers. But how does a GraphQL server source that data in the first place? Apollo Server data sources are a collection of classes that encapsulate the code for interacting with different data services, e.g. Mongo DB, REST API. Read along to learn about the current state of data fetching and how to write your own data source library
The GraphQL connection specification is a pattern for implementing cursor-based pagination. This article by Andrew Ingram addresses common misconceptions around it and the reasons for choosing connections as a pagination implementation over limit-offset pagination.

The GraphQL ecosystem grows with more database connectors. GRANDstack is a frontend-backend-database stack with the Neo4j Graph Database. In a similar spirit to GraphQL-to-SQL mapping tools, GRANDstack helps build GraphQL APIs that leverage the Neo4j graph database. Watch this 20-minute video which covers bootstrapping an application, the development workflow, and deployment to Netlify.
