Graphql Php
This project is a PHP implementation of the GraphQL specification. It provides a suite of tools for building servers that process queries and mutations, including a schema parser, an execution engine for evaluating operations, and a toolkit for manipulating abstract syntax trees.
The library differentiates itself through a specialized AST toolkit that allows for the inspection, modification, and printing of GraphQL abstract syntax trees. It also includes a mechanism for deferred field resolution to enable asynchronous data fetching and prevent blocking the primary execution thread.
The implementation covers broad capability areas including schema management via the schema definition language, rule-based document validation for security, and formatted error handling to ensure specification-compliant responses.
Features
- GraphQL Servers - Provides a full PHP implementation for building backend servers that process GraphQL queries and mutations.
- Document Validation - Includes a rule-based validation system that checks GraphQL documents against a schema to ensure structural and type correctness.
- GraphQL Document Validations - Implements a rule-based validation system that ensures GraphQL queries adhere to the defined schema before execution.
- GraphQL AST Parsing - Provides the core mechanism for converting GraphQL query strings into abstract syntax trees for further processing.
- Schema-Based Execution - Implements the core engine that maps GraphQL query fields to resolver functions based on the schema.
- GraphQL Execution Engines - Implements the runtime engine that executes GraphQL operations against a schema to return data.
- GraphQL Operation Processing - Handles the end-to-end lifecycle of parsing, validating, and resolving GraphQL operations.
- GraphQL Schema Definitions - Provides the capability to define and map internal data models to a typed GraphQL schema.
- SDL Parsers - Provides utilities to parse Schema Definition Language strings into executable GraphQL schema objects.
- SDL Schema Generation - Generates functional GraphQL schema instances from SDL strings or parsed ASTs.
- GraphQL Schema Parsing - Implements the core process of converting GraphQL schema definition language into an internal executable structure for query processing.
- GraphQL Development Tooling - Offers a suite of programmatic utilities for inspecting and modifying GraphQL schemas and queries.
- AST String Printing - Includes a utility to convert abstract syntax trees back into human-readable GraphQL strings.
- AST Modification - Allows for the programmatic mutation and replacement of nodes within a GraphQL abstract syntax tree.
- AST Visitor Patterns - Implements a visitor pattern for traversing and manipulating GraphQL abstract syntax trees.
- GraphQL Deferred Fields - Provides a mechanism for deferred field resolution to enable asynchronous data fetching and prevent blocking the execution thread.
- GraphQL AST Toolkits - Ships a specialized toolkit for the inspection, modification, and printing of GraphQL abstract syntax trees.
- Schema SDL Printers - Provides a printer to export the internal schema representation into human-readable Schema Definition Language.
- PHP GraphQL Tools - Reference implementation of GraphQL for PHP.
