json-graphql-server

json-graphql-server version 3.3.1 is a zero-configuration GraphQL testing and mocking tool for Node.js. Given a JSON data file or JavaScript module exporting arrays of entities, it spins up a full GraphQL API (queries, mutations, filters, pagination, sorting, and relationships) on localhost in under 30 seconds, no schema writing needed. Released under MIT with contributors from Marmelab; updates are infrequent but stable. Compared to alternatives like json-graphql-mocker or graphql-faker, this tool provides automatic schema generation and GraphiQL IDE out of the box, but does not support authentication, custom resolvers, or complex business logic.
