Description: A Node Schema defines the structure of nodes in a GraphQL API. In this context, a ‘node’ refers to an entity that can be queried or manipulated through the API. The schema establishes the relationships between different nodes and their fields, allowing developers to define how data is structured and how it can be accessed. Each node can have multiple fields, which can be of different types, including scalar types like strings or integers, as well as complex types representing other nodes. This flexibility allows for the construction of highly customizable and efficient APIs, where clients can request exactly the information they need without overloading the network with unnecessary data. Additionally, the node schema is fundamental for query validation, ensuring that requests made by clients conform to the defined structure, which enhances the robustness and security of the API. In summary, the Node Schema is an essential component in the architecture of GraphQL, providing a solid foundation for interaction between clients and servers.
