HotChocolate is a GraphQL server implementation for .NET that handles queries, mutations, and subscriptions over HTTP. It provides code-first schema generation directly from C# classes and attributes, keeping the schema and business logic in sync without manual type definitions. The project also includes a GraphQL gateway that composes multiple GraphQL and REST endpoints into a single unified schema, along with a GraphQL IDE for exploring, testing, and debugging GraphQL APIs interactively. The project distinguishes itself through its comprehensive tooling ecosystem, which includes a GraphQL c
graphql-tools is a toolkit for constructing, modifying, and combining GraphQL schemas. It provides a suite of utilities for parsing Schema Definition Language, managing resolver bindings, and assembling executable schemas. The project enables the composition of unified GraphQL gateways by merging multiple independent subschemas through schema stitching. This includes capabilities for entity type merging, type extension, and field resolution delegation to route requests across different services. The toolkit also includes a mocking engine that generates simulated GraphQL schemas and data. Thi
GraphQL.NET is a server-side framework for building and executing GraphQL APIs within C# applications. It provides a comprehensive toolkit for schema building, a federated engine for distributed data graphs, and a subscription handler for managing real-time data streams. The project distinguishes itself with a flexible schema builder that supports both programmatic code-first definitions and declarative schema-first approaches using the standard schema definition language. It includes a dedicated federation engine to split data graphs into subgraphs and compose them into a unified gateway, as
graphql-tools is a GraphQL schema orchestration library and toolkit designed for building, merging, and extending schemas. It provides an SDL-first schema generator that transforms Schema Definition Language strings and resolver maps into executable schema instances. The project features a dedicated schema stitching tool for combining multiple independent GraphQL schemas into a single unified API gateway. It also includes a GraphQL mocking engine that simulates backends by generating synthetic data based on schema definitions. The toolkit covers a broad range of composition capabilities, inc
