GraphQL Q&A

December 5, 2024

GraphQL is a flexible query language for APIs that allows clients to request specific data, receiving precisely tailored JSON responses. It uses a schema (the API’s blueprint) to define available data and operations (queries, mutations, subscriptions). Clients communicate via HTTP POST requests to a single endpoint, and the server uses resolvers to fetch data from various sources. Key concepts include SDL, types, resolvers, and the distinction between schema (server-side definition) and client queries (data requests).
