Apollo Server

Apollo Server is an open-source tool designed to help developers create and manage APIs using GraphQL, a modern query language for APIs. It allows applications to flexibly request data from a server, making it easier for clients to get exactly the information they need in a single request. Apollo Server simplifies the process of defining data types and relationships, handling requests, and integrating with various data sources. It provides features like caching and real-time updates, improving performance and user experience while enabling efficient communication between the front-end (user interface) and back-end (server).
