Features

• GraphQL APIs - Provides a framework for exposing data models through automatically generated type-safe GraphQL interfaces.
• GraphQL Schema Generation - Provides a framework to generate GraphQL schemas and resolvers using TypeScript classes and decorators as the source of truth.
• GraphQL - Provides a library for implementing GraphQL queries and mutations via typed controller classes.
• Schema Generation - Uses class decorators to automatically derive GraphQL schemas from TypeScript metadata at runtime.
• Single-Source-of-Truth Modeling - Uses TypeScript classes as the shared primary definition for both data models and the GraphQL schema.
• Field Resolvers - Implements field resolvers within controller classes to handle data fetching and mutations.
• GraphQL Schema Definitions - Defines GraphQL schemas and types using TypeScript classes to maintain a single source of truth.
• Schema-First Development Frameworks - Prioritizes typed classes as the source of truth for generating the GraphQL schema and logic.
• Type-Safe API Frameworks - Leverages the TypeScript static type system to ensure the GraphQL schema and API contracts align.
• Resolver Mappings - Maps GraphQL queries and mutations to specific methods within controller classes using metadata reflection.
• Access Control Guards - Uses guards to block unauthorized requests to specific GraphQL resolvers based on security policies.
• Input Validation - Verifies and sanitizes incoming GraphQL arguments against defined rules to ensure data integrity.
• Dependency Injection Containers - Provides an inversion-of-control container to decouple business logic from GraphQL resolvers.
• Dependency Injection - Decouples business logic from the API by injecting required service dependencies into resolvers.
• Metadata Reflection Frameworks - Utilizes reflect-metadata to dynamically inspect decorated class properties for schema generation.
• Request Interception Middleware - Implements a chain of guards and validation functions that intercept requests before they reach resolvers.
• Controller-Based Organization - Structures business logic and data fetching using class-based controllers and dependency injection.
• Web Framework Integrations - TypeScript-based framework for building GraphQL APIs.
• Web Frameworks - Framework for creating GraphQL APIs using TypeScript classes and decorators.
