Graphql Php
Dieses Projekt ist eine PHP-Implementierung der GraphQL-Spezifikation. Es bietet eine Suite von Tools zum Aufbau von Servern, die Queries und Mutations verarbeiten, einschließlich eines Schema-Parsers, einer Execution-Engine zur Auswertung von Operationen und eines Toolkits zur Manipulation von Abstract Syntax Trees (AST).
Die Bibliothek zeichnet sich durch ein spezialisiertes AST-Toolkit aus, das die Inspektion, Modifikation und Ausgabe von GraphQL-ASTs ermöglicht. Zudem enthält sie einen Mechanismus für Deferred Field Resolution, um asynchrones Daten-Fetching zu ermöglichen und ein Blockieren des primären Execution-Threads zu verhindern.
Die Implementierung deckt breite Funktionsbereiche ab, darunter Schema-Management via Schema Definition Language (SDL), regelbasierte Dokumentenvalidierung für Sicherheit sowie formatiertes Error-Handling, um spezifikationskonforme Antworten sicherzustellen.
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.
