Graphql Tools
graphql-tools es un kit de herramientas para construir, modificar y combinar esquemas GraphQL. Proporciona un conjunto de utilidades para analizar el lenguaje de definición de esquemas (SDL), gestionar bindings de resolvers y ensamblar esquemas ejecutables.
El proyecto permite la composición de gateways GraphQL unificados mediante la fusión de múltiples subesquemas independientes a través de schema stitching. Esto incluye capacidades para la fusión de tipos de entidades, extensión de tipos y delegación de resolución de campos para enrutar solicitudes a través de diferentes servicios.
El kit de herramientas también incluye un motor de mocking que genera esquemas y datos GraphQL simulados. Este sistema admite la generación de valores personalizados, simulación de mutaciones y mocking de resultados paginados para simular el comportamiento del backend sin un servidor en vivo.
Utilidades de desarrollo adicionales cubren la validación de cobertura de resolvers y la adjunción de documentación a tipos y campos.
Features
- GraphQL Schema Stitching - Combines several independent GraphQL schemas into a single unified API gateway.
- Schema Stitching Gateways - Combines multiple independent GraphQL services into a single unified gateway via schema stitching.
- GraphQL API Mocking - Creates simulated GraphQL backends with custom data generators to enable frontend development without a live server.
- GraphQL Mocking Engines - Generates simulated GraphQL schemas and data to enable frontend development without a backend.
- GraphQL - Routes field resolution across multiple subschemas to unify data from different services into one endpoint.
- Field Resolvers - Binds resolver functions to a GraphQL schema to define how specific fields are fetched or computed.
- Field Delegation - Implements field resolution delegation to route requests across multiple subschemas in a unified gateway.
- Resolver Binding Managers - Binds resolver functions to GraphQL fields and validates coverage across the schema.
- GraphQL Schema Composition Tools - Merges multiple GraphQL type definitions and schemas into a single unified API gateway.
- GraphQL Schema Construction - Combines type definitions and resolver functions into a single executable schema from distributed sources.
- Schema-First Mapping - Maps resolver functions to a pre-defined schema structure by parsing schema definition language strings.
- SDL Parsers - Converts Schema Definition Language strings into executable GraphQL schema objects.
- GraphQL Schema Generation - Creates schema instances by combining schema definition language strings with corresponding resolver functions.
- Schema-First Development Frameworks - Prioritizes schema definition as the source of truth for API generation.
- SDL Schema Generation - Creates functional schemas from definition language strings with support for resolvers, interfaces, and unions.
- Scalar-Based Mocking - Creates a schema that returns simulated data based on scalar types to enable rapid prototyping.
- Mock Value Generators - Provides utilities to generate randomized or predefined mock data based on GraphQL scalar types.
- Entity Type Unification - Unifies different type definitions from multiple services that refer to the same entity to fetch fields from multiple sources.
- GraphQL Development Tooling - Provides utilities for validating resolver coverage and attaching documentation to GraphQL types and fields.
- GraphQL Response Simulation - Simulates API responses with per-type mocking to enable prototyping without active data sources.
- GraphQL Mock Value Customization - Defines specific return values or generator functions for scalars and object types to simulate realistic data models.
- Resolution Delegation - Extends unified schemas by adding fields that route the resolution process to another subschema.
- API Mocking Servers - Simulates a backend server in development environments to decouple frontend and backend work.
- Resolver Coverage Validation - Checks schemas to ensure required resolvers exist for arguments, non-scalar fields, or interface types.
- Type Definition Merging - Merges multiple type definition strings into a consolidated schema definition while resolving conflicts.
- Type Extensions - Adds new fields to existing types across multiple schema definitions to prevent oversized root lists.
- GraphQL Development Tools - Tool library for building and maintaining GraphQL-JS servers.
