Features

• GraphQL Schema Stitching - Combines multiple independent GraphQL schemas into a single unified gateway through programmatic configuration and field delegation.
• Mock Data Generators - Provides an engine that produces synthetic data by traversing schemas and applying type-specific generators.
• GraphQL API Mocking - Creates functional GraphQL schemas that return simulated data to support rapid prototyping and frontend development.
• GraphQL Mocking Engines - Generates synthetic data and simulated GraphQL backends based on schema definitions for rapid prototyping.
• Field Delegation - Implements mechanisms for routing field resolution from a unified schema to specific subschemas for cross-service data fetching.
• Resolver Binding Managers - Provides tools for binding resolver functions to schema fields to handle data fetching for queries and mutations.
• GraphQL Schema Composition Tools - Merges multiple GraphQL type definitions and resolver maps into a single executable schema for a unified API.
• GraphQL Schema Generation - Merges type definitions and resolver functions into a single executable schema to process incoming requests.
• SDL Schema Generation - Builds executable GraphQL schemas by parsing Schema Definition Language strings and binding them to resolver maps.
• GraphQL Schema Management - Provides a comprehensive toolkit for building, merging, and maintaining modular GraphQL schema definitions.
• Schema Stitching Gateways - Combines disparate GraphQL schemas into a unified gateway using programmatic configuration and schema extensions.
• Entity Type Unification - Implements unification of divergent type definitions from multiple services that represent the same entity into a single type.
• GraphQL Mock Value Customization - Allows defining specific return values or generator functions for various scalar and object types during simulation.
• Schema Modularization - Provides mechanisms to organize GraphQL type definitions and resolvers across multiple files for better maintainability.
• Mock Mutation Simulation - Maintains a persistent data cache to ensure that mutations correctly update values for subsequent mocked queries.
• Introspection-Based Mocking - Generates mockable schemas by analyzing the results of GraphQL introspection queries from external APIs.
• GraphQL Resolver Organization - Organizes GraphQL type definitions and resolvers across multiple files to maintain a scalable codebase.
• Union Types - Determines the specific object type of a result when a GraphQL field returns a union or interface.
• Type Definition Merging - Consolidates disparate GraphQL type strings and objects into a single unified definition before schema instantiation.
• Type Extensions - Supports adding new fields to existing types using extension keywords to modularize schema definitions.
