Autorest

AutoRest is a multi-language SDK generator and OpenAPI code generator designed to produce consistent software development kits from a single API definition. It functions as a REST API client generator that transforms Swagger and OpenAPI specification files into functional, typed HTTP client libraries.

The tool automates the SDK development workflow by converting design documents into source code, ensuring that the resulting implementations match the defined API contract across different programming languages.

The system employs specification-driven development using an intermediate representation to normalize data before applying language-specific generation logic. It utilizes template-based code generation and pluggable client templates to map abstract API specifications into diverse syntax patterns for multiple target runtimes.

Features

  • API Client SDK Generators - Transforms OpenAPI specifications into type-safe client SDKs for multiple programming languages.
  • OpenAPI Client SDK Generators - Automates the creation of client SDKs and type definitions specifically from OpenAPI specifications.
  • OpenAPI Specification Parsers - Parses OpenAPI JSON and YAML definitions into internal representations to drive the code generation process.
  • REST API Client Generators - Creates typed HTTP clients for interacting with RESTful services based on standardized specifications.
  • API Contract Implementations - Turns OpenAPI design documents into functional code to ensure the implementation matches the defined API contract.
  • API-Driven Development Workflows - Streamlines the production and maintenance of SDKs by integrating automated code generation into the development lifecycle.
  • Specification-Driven Development Tools - Automates the transformation of structured OpenAPI definition files into executable client libraries through a deterministic mapping process.
  • API Client Generators - Converts OpenAPI specifications into functional client libraries across several programming languages to simplify web API connections.
  • Multi-Language Client Generation - Generates official client libraries across various programming languages from a common API specification.
  • Template-Based Code Generators - Produces source code by injecting specification values into predefined language-specific text templates.
  • Cross-Language SDK Integration - Builds consistent web service integrations across different tech stacks from a single shared API definition.
  • Generation Templates - Provides pluggable client templates that allow language definitions to be updated without altering the core specification parser.
  • Intermediate Representations - Implements a normalized internal data model to decouple raw OpenAPI specifications from language-specific generation logic.
  • Multi-Language Grammar Mapping - Translates abstract API specifications into diverse syntax patterns across multiple programming language runtimes using shared core logic.
  • API Client Development Tools - Generates client libraries for RESTful services.
  • API Development - Generates client SDKs from OpenAPI specifications.
