Key Features
Schema Definition Language (SDL): According to the vendor, GraphQL provides a type system called SDL, allowing developers to define the structure of data in a GraphQL API. With SDL, developers can define types, fields, and relationships, providing a clear and concise description of their API.
Strong Typing: The vendor states that GraphQL enforces strong typing, ensuring that data is returned in the expected format. This is said to help catch errors early on, improving the overall stability and reliability of the API.
Single Request, Multiple Responses: According to the vendor, clients can request multiple resources in a single GraphQL request, which can reduce the number of round trips to the server and potentially improve performance.
Hierarchical Queries: GraphQL allows clients to specify the exact data they need, aiming to avoid over-fetching or under-fetching of data. This is said to provide flexibility and efficiency in retrieving data.
Real-time Updates with Subscriptions: According to the vendor, GraphQL supports real-time updates through subscriptions. Clients can subscribe to specific data changes and receive real-time updates, making it suitable for building applications like chat apps or live dashboards.
Introspection: GraphQL APIs provide introspection capabilities, allowing clients to query the API schema. This enables developer tools like GraphQL Playground or GraphiQL, providing auto-completion and documentation features.
Versioning and Evolution: According to the vendor, GraphQL allows for versioning and evolution of APIs without breaking existing clients. Clients can explicitly request the version they need, ensuring compatibility and facilitating smooth transitions.
Batching and Caching: GraphQL enables clients to batch multiple queries into a single request, potentially reducing network overhead. Additionally, it supports caching of data at the network level, which may improve performance.
Error Handling: GraphQL provides a standardized way to handle errors and return informative error messages, according to the vendor. This allows clients to handle errors gracefully and provide meaningful feedback to users.
