OpenAPI Auto Components

This package provides a utility function autoComponents that automatically extracts JSON schemas from request bodies and response bodies and moves them into the components section as schemas. The title of the schema is used for the key in the components section. Note that you can't have duplicate titles for different schemas.

Demo

import { autoComponents } from "openapi-auto-components";

const spec = { /.../ };

const specWithComponents = autoComponents(spec);
