support callbacks

[nfroidure]

See this callbacks example.

To do:

• types generator support Generate types for callbacks schema2dts#39,
• check this works fine with callbacks:

  whook/packages/whook/src/libs/openapi.ts

  Lines 23 to 59 in 87fe576

  	export function cleanupOpenAPI(
  	api: OpenAPIV3_1.Document,
  	): OpenAPIV3_1.Document {
  	const seenRefs = [
  	...new Set(
  	collectRefs(
  	api as unknown as JsonObject,
  	api.paths as unknown as JsonValue,
  	),
  	),
  	];
  	return {
  	...api,
  	components: {
  	...(Object.keys(api?.components || {}) as ComponentType[]).reduce(
  	(cleanedComponents, componentType) => ({
  	...cleanedComponents,
  	[componentType]: COMPONENTS_TYPES.includes(componentType)
  	? Object.keys(api?.components?.[componentType] || {})
  	.filter((key) =>
  	seenRefs.includes(`#/components/${componentType}/${key}`),
  	)
  	.reduce(
  	(cleanedComponents, key) => ({
  	...cleanedComponents,
  	[key]: api.components?.[componentType]?.[key],
  	}),
  	{},
  	)
  	: api.components?.[componentType],
  	}),
  	{},
  	),
  	},
  	};
  	}

• think of the integration level: we could generate the API SDK in the watch function and add callback implementation utilities (see Allow to create a callbacks SDK openapi-ts-sdk-builder#17 ).
