FAQPage Schema

How do I generate an OpenAPI 3.1 specification from existing Python FastAPI code?▼

To generate an OpenAPI 3.1 specification from Python FastAPI code, use a code-first workflow template that automatically scaffolds and extracts API structures directly from your codebase into a complete spec.

What is the best way to validate API documentation against the OpenAPI 3.1 standard?▼

Validating API documentation against the OpenAPI 3.1 standard involves applying built-in linting templates to your specifications, ensuring consistent API contracts and compliance across design-first and code-first workflows.

Can I use TypeScript and tsoa for code-first OpenAPI spec generation?▼

Yes, you can use TypeScript and tsoa for code-first OpenAPI spec generation by applying specialized templates that scaffold OpenAPI 3.1 structures matching your TypeScript design artifacts and code inputs.

Does this approach support both design-first and code-first API documentation workflows?▼

Yes, this approach supports design-first, code-first, and hybrid workflows, allowing you to generate, validate, and publish OpenAPI 3.1 specifications regardless of whether you start from design artifacts or existing code.

How do I create a complete OpenAPI 3.1 spec scaffold from scratch?▼

You create a complete OpenAPI 3.1 spec scaffold from scratch by utilizing built-in templates that structure your initial design artifacts into a valid, publishing-ready API specification.

Why does my OpenAPI specification lag behind my evolving API codebase?▼

OpenAPI specifications lag behind evolving APIs when generated manually, but automating spec generation from code and validation patterns ensures documentation stays synchronized and prevents integration challenges.
