Význam: GraphQL - Jazyk datových dotazů vyvinutý Facebookem v roce 2012 před oficiálním vydáním v roce 2015. Poskytuje alternativu k architekturám webových služeb REST a ad-hoc.

GraphQL has its own type system that’s used to define the schema of an API. The syntax for writing schemas is called Schema Definition Language (SDL). Here is an example of how we can use the SDL to define a simple type called Person : GraphQL for .NET. Fragments. Fragments let you construct sets of fields and then include them in queries where you need to. GraphQL je spojení mezi blockchainovými daty a aplikací, kterou jim chce uživatel poskytnout. Prostřednictvím grafického uzlu poté mohou uživatelé doručovat vyhledávání na platformu. Po celém procesu se uživatelé mohou podívat na výsledky svých dotazů ze svých aplikací.

GraphQL can drastically simplify the number and complexity of routes, e.g., versus a standard REST project. Performance arguments can be as well, but again, you need an apples-to-apples comparison. A big part of the purpose of GraphQL is to eliminate the multiple round-trips. If that’s not a pain point for you, maybe it’s not necessary.

GraphQL provides a complete and understandable description of the data in your API, gives clients the power to ask for exactly what they need and nothing more, makes it easier to evolve APIs over time, and enables powerful developer tools.

GraphQL presents new ways for clients to fetch data by focusing on the needs of product developers and client applications. It provides a way for developers to specify the precise data needed for a view and enables a client to fetch that data in a single network request.
