Features

• Server Implementations - Implements a full GraphQL server specification in Go to handle structured data queries and mutations.
• Query Structural Handling - Processes complex GraphQL requests involving aliases, fragments, and nested object lookups.
• Document Validation - Checks documents against a schema using specification rules to identify structural or type errors.
• Query Parsers - Converts raw GraphQL query strings into abstract syntax trees to enable validation and execution.
• Query Validators - Validates that arguments used in a query exist in the schema and suggests corrections.
• Type System Mappings - Uses reflection to automatically map native Go structs to GraphQL object definitions and types.
• Schema Introspection - Provides meta-fields and types that allow clients to query the server for its schema structure.
• Field Selection Validation - Verifies that requested fields exist on the specified types and returns errors for undefined fields.
• Mutation Handlers - Executes state-changing mutations serially to ensure requested processing order is maintained.
• Operation Execution - Executes queries, mutations, and subscriptions against a schema to resolve and return structured data.
• Query Planning - Analyzes the GraphQL query and schema to construct an optimized data fetching path before execution.
• Field-to-Model Mappers - Maps GraphQL schema fields to Go-specific data fetching logic and resolver functions.
• Plugin Argument Validators - Verifies that values passed to arguments match the expected scalar or enum types defined in the schema.
• Resolver Context Injectors - Injects request-scoped metadata and state throughout the resolver tree to manage authentication and shared connections.
• Strongly-Typed Query Validation - Validates incoming GraphQL queries against a predefined type system to ensure structural and type-level correctness.
• Response Formatting - Provides structured response objects containing resolved data and execution errors in accordance with the GraphQL specification.
• GraphQL AST Parsing - Implements a parser that converts raw GraphQL query strings into abstract syntax trees for structural analysis.
• Reflection-Based Type Mapping - Automatically derives GraphQL object definitions and fields from native Go structs using reflection and struct tags.
• Recursive Schema Resolvers - Traverses the schema recursively to execute resolver functions and retrieve data for requested fields.
• Argument Uniqueness Validation - Ensures that each field or directive contains only one instance of any given argument name.
• Fragment Data Masking - Analyzes fragments to ensure spread fragments are compatible with the parent type definition.
• Query Execution Engines - Implements a runtime engine that determines the optimal execution path for GraphQL queries through lazy expansion.
• GraphQL Schema Construction - Provides tools to define types, queries, and mutations to establish the structured data model used for validation and execution.
• Schema Engines - Provides a schema engine for defining the types and interfaces required to validate and execute GraphQL operations.
• Schema Modeling - Provides tools for designing structured data models using types, mutations, and custom scalars.
• GraphQL Subscriptions - Implements real-time data streaming via GraphQL subscriptions using event source functions.
• Enumeration Types - Supports custom types with a fixed set of allowed values to restrict input and standardize output.
• Struct-to-Argument Mapping - Derives GraphQL argument definitions directly from native Go struct properties to simplify input handling.
• Scalar Types - Implements standard scalar data types like integers and floats to ensure values conform to the GraphQL specification.
• Custom Scalar Marshaling - Converts internal Go data types into their corresponding GraphQL scalar representations.
• Custom Scalars - Allows the definition of new primitive data types beyond the standard specification to handle specialized data formats.
• Scalar Parsing - Converts input strings and literals into strongly typed native objects like dates and times.
• GraphQL Root Types - Implements mechanisms to configure the root query, mutation, and subscription types as primary API entry points.
• Query Normalization - Replaces literal field arguments with synthetic variables to create a canonical query shape for execution caching.
• Query Plan Caching - Stores parsed and validated query states in a cache to eliminate expensive repeated computations on frequent requests.
• Query Shape Normalization - Normalizes GraphQL queries into a canonical form to improve the hit rate of execution plan caches.
• Circular Reference Detection - Detects and blocks recursive fragment references to prevent infinite loops during query execution.
• Extensible Processing Pipelines - Provides an extensible pipeline for injecting custom logic into the parsing, validation, and execution phases of a request.
• Parser State Tracking - Maintains a stack of field and type definitions during AST traversal to track parsing state.
• Request Context Management - Passes metadata and state through the execution chain to share authentication and connections across resolvers.
• Concurrent Resolver Execution - Processes multiple data fetching requests in parallel to minimize response latency for complex queries.
• GraphQL Abstract Type Definitions - Provides mechanisms to group related object types or allow fields to return one of several different object types.
• Union Types - Enables the definition of union types to allow fields to return any of several different object types at runtime.
• Directive-Based Execution - Controls the inclusion or exclusion of fields in a response based on boolean directives.
• GraphQL Directive Definitions - Enables the creation of directives that modify execution behavior or schema metadata via names, locations, and arguments.
• GraphQL Input Type Definitions - Allows specifying the structure of complex objects that can be passed as arguments to queries or mutations.
• GraphQL Interface Type Definitions - Supports abstract types that define a set of fields that multiple object types must implement.
• List Types - Provides support for defining list types within the GraphQL schema to handle collections of data.
• GraphQL Variable Management - Manages dynamic input values and default arguments to customize query and mutation execution.
• Real-Time Data Streaming - Implements GraphQL subscriptions to push real-time data updates to clients over long-lived connections.
• Type-Safe API Integrations - Ensures API requests are strictly validated against a schema before data resolution to maintain type safety.
• Query Languages - Implementation of GraphQL for Go.
• Go GraphQL Tools - Go implementation of the GraphQL specification.
