Why a GraphQL API?
GraphQL is a powerful query language for APIs, developed by Meta in 2015 in response to the growing complexity of data retrieval requirements in modern applications.
At Qytrees, the adoption of GraphQL is motivated by its effective handling of strongly typed nodes, which are particularly well-suited for modeling financial data, including derivatives. GraphQL's structure, defining data through nodes and edges, facilitates the creation of sophisticated, interconnected data models. This allows for complex requests that seamlessly combine analytics with data retrieval, adhering to a methodical approach:
- Describe the data: Users may configure specific data requirements, such as defining future contracts with maturities in tenors.
- Specify data to fetch: Users can define precise data needs from the API, like requesting only the valuation and maturity dates for the data structure described previously.
- Expect predictable results: The GraphQL API responds with data that matches the user's specified request if available.
Key Features of GraphQL
Unlike traditional REST APIs, which require multiple requests to different URLs, a GraphQL API consolidates data requests into a single call. This consolidation can significantly enhance application stability and response times, depending on the type of queries. Key features include:
- Efficient Data Loading: Clients precisely specify what they need, significantly reducing data over-fetching or under-fetching.
- Single Endpoint: All requests are routed through a single endpoint, simplifying the data retrieval process. However, while this reduces the complexity of managing multiple endpoints, it increases the responsibility of the client to write accurate and efficient queries.
- Real-time Updates: GraphQL subscriptions provide real-time data updates, enabling dynamic and responsive applications.
- Strongly Typed: The API's strict schema ensures that interactions are predictable and strictly conform to the defined data structures.
These features underscore why GraphQL is the preferred choice for our data API needs, ensuring efficient, reliable, and precise data delivery.
Understanding the GraphQL Schema
The schema in GraphQL is fundamental, as it defines the structure of data and specifies exactly how nodes are interconnected. This schema serves as a contract between the server and client, detailing available types and the ways they can be queried. For details on how Qytrees implements its GraphQL schema, refer to our detailed GraphQL API documentation.
Today, GraphQL is maintained by a large community of developers and is employed by teams of all sizes, from startups to major organizations like GitHub, Shopify, and Twitter. Its adaptability, efficiency, and robust developer tools have made it a preferred choice for developers handling complex API systems.
At Qytrees, we leverage this cutting-edge technology to provide you with easy and intuitive access to data and analytics, improving the speed and accuracy of your decision-making processes.
