Graphql Tools
graphql-tools est une boîte à outils pour construire, modifier et combiner des schémas GraphQL. Elle fournit une suite d'utilitaires pour parser le Schema Definition Language (SDL), gérer les bindings de résolveurs et assembler des schémas exécutables.
Le projet permet la composition de passerelles GraphQL unifiées en fusionnant plusieurs sous-schémas indépendants via le schema stitching. Cela inclut des capacités pour la fusion de types d'entités, l'extension de types et la délégation de résolution de champs pour router les requêtes à travers différents services.
La boîte à outils inclut également un moteur de mocking qui génère des schémas et des données GraphQL simulés. Ce système prend en charge la génération de valeurs personnalisées, la simulation de mutations et le mocking de résultats paginés pour simuler le comportement du backend sans serveur actif.
Des utilitaires de développement supplémentaires couvrent la validation de la couverture des résolveurs et l'attachement de documentation aux types et champs.
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.
