GraphQL · Class

Source

GraphQL is a typed language for querying APIs and a server runtime that executes those queries. A schema defines the available fields, and resolvers provide their values.

Last updated

Syntax

type Query { field: Type }\n\nquery { field }

In-depth API docs are only for subscribers: parameters, examples, common mistakes and interview practice.
