Juniper
Juniper est une bibliothèque de serveur GraphQL et un moteur de schéma pour Rust. Il fournit une boîte à outils pour construire des API typées en toute sécurité en mappant les structures de données natives Rust vers des objets, entrées et scalaires GraphQL. Le projet fonctionne comme un moteur d'exécution qui peut traiter les requêtes et les mutations soit via un serveur réseau, soit comme un moteur sans tête pour une exécution locale.
La bibliothèque est agnostique vis-à-vis de l'exécution, ce qui lui permet de faire le pont entre le traitement GraphQL et divers frameworks web Rust asynchrones. Elle inclut un framework d'abonnement qui gère les connexions WebSocket persistantes pour pousser des mises à jour de données en temps réel aux clients.
Le moteur couvre une large surface de capacité, notamment l'exportation de langage de schéma, la gestion du contexte d'état partagé pour l'injection de dépendances et une approche code-first pour définir les résolveurs. Il prend également en charge l'intégration de types de données spécialisés tels que les décimaux et les horodatages pour éviter les conversions de données manuelles.
Features
- GraphQL API Implementations - Provides a full toolkit for implementing type-safe GraphQL APIs by mapping native Rust structures to a schema.
- GraphQL Type Mappings - Maps native Rust language types to GraphQL objects using trait interfaces and procedural macros.
- GraphQL Subscriptions over WebSocket - Implements GraphQL subscriptions over WebSockets to deliver real-time data updates from the server to connected clients.
- Language-Specific Type Mappings - Translates native Rust data structures into GraphQL objects, inputs, and scalars using a code-first approach.
- Field Resolvers - Allows the definition of query and mutation field resolvers that execute business logic and access shared state.
- GraphQL Execution Engines - Provides a GraphQL execution engine capable of processing queries and mutations independently of a network server.
- GraphQL Schema Definitions - Maps internal Rust data models to a typed GraphQL schema using a code-first toolkit.
- GraphQL Servers - Serves as a comprehensive Rust library for building GraphQL servers by defining schemas and resolvers.
- GraphQL Subscriptions - Implements server-side GraphQL subscriptions to push real-time data updates to clients via persistent connections.
- Web Framework Integrations - Binds the GraphQL schema engine to various asynchronous HTTP server frameworks to handle network requests.
- External Type Integrations - Integrates specialized types from external libraries, such as timestamps and decimals, directly into the GraphQL schema.
- Stream Subscriptions - Implements a stream-oriented subscription model to push real-time data updates to clients via WebSockets.
- GraphQL Schema Exports - Generates a standard GraphQL schema language representation (SDL) for use in external tools and documentation.
- Native-to-UI Type Mappings - Maps native Rust data structures into a type-safe GraphQL schema using a code-first approach.
- Resolver Context Injection - Injects a shared user-defined context object into field resolvers to provide access to databases and external services.
- WebSocket Transports - Utilizes WebSocket protocols to facilitate bidirectional, real-time communication for GraphQL data operations.
- GraphQL Resolver Dispatch - Routes GraphQL queries to specific function handlers based on the type definitions mapped in the schema.
- Schema Generation Macros - Uses procedural macros to automatically derive GraphQL schema definitions from native Rust data structures.
- Context Sharing - Injects a shared context object into field resolvers to provide access to databases and external services.
- Web Framework Decoupling - Decouples GraphQL processing logic from the underlying asynchronous runtime to support multiple HTTP frameworks.
- Asynchronous Request Handlers - Processes GraphQL requests using asynchronous handlers to maintain high concurrency across different runtimes.
- GraphQL Integration Middleware - Bridges GraphQL execution logic into asynchronous Rust web frameworks via integration middleware.
- Query Execution Engines - Provides a runtime engine that evaluates GraphQL queries against a schema to produce data without requiring a network server.
- Spec-Compliant GraphQL Servers - Provides a server implementation that adheres to GraphQL specifications for processing HTTP requests.
- Data Processing - GraphQL server library for Rust.
- Server Libraries - GraphQL server library for the Rust ecosystem.
