SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

OpenAPI documentation and type-generation workflow that lets teams define, validate, and document APIs with a single source of truth.

Core Features & Use Cases

  • OpenAPI document authoring and generation for REST APIs.
  • TypeScript type generation and validation to ensure contract-consistency between server and client.
  • Code generation for clients and server stubs to accelerate integration and development.

Quick Start

Create an openapi.yaml document and run the provided tooling to generate TypeScript types and a client for your API.

FAQPage Schema
How do I generate TypeScript types from an OpenAPI specification?▼

You can generate TypeScript types from an OpenAPI specification by defining your API contract in an openapi.yaml file and running the provided toolchain to produce contract-consistent TypeScript types for your project.

What is the best way to maintain API documentation and client code consistency?▼

The best way to maintain API documentation and code consistency is using a contract-first OpenAPI workflow, defining a single source of truth that generates both API documentation and TypeScript client SDKs.

Can I use OpenAPI for contract-first API design in a TypeScript project?▼

Yes, you can use OpenAPI for contract-first API design in TypeScript projects by authoring an OpenAPI 3.1 specification to validate REST APIs and generate server stubs alongside client code.

How do I generate a client SDK from an OpenAPI YAML file?▼

To generate a client SDK from an OpenAPI YAML file, you create your openapi.yaml document and run the provided generation utilities to produce the client code required for API integration.

Do I need specific dependencies to run OpenAPI code generation?▼

Yes, OpenAPI code generation requires an OpenAPI toolchain including openapi-typescript and openapi-generator, an OpenAPI YAML or JSON spec, and a TypeScript project to consume the generated types and clients.

Why use a single OpenAPI specification for REST API development?▼

Using a single OpenAPI specification for REST API development lets teams define, validate, and document APIs with a single source of truth, preventing contract drift between server and client implementations.
