OpenAPI3 migration. Paths section

[yarax]

Please see the migration roadmap https://github.com/yarax/swagger-to-graphql/wiki/OpenAPI3-migration
Among things that I noticed so far:

• [Feature request] Support pathDefinition.parameters OpenAPI property #65
• [Feature request] Default operation.description to operation.summary #66
• [Feature request] Support OpenAPI 3.0 #58
• [Feature request] Support defaultValue in GraphQL arguments #60
• servers section

[0xR]

The servers section is already supported and under test:

swagger-to-graphql/src/swagger.js

Lines 50 to 81 in d2c51e5

	export const getServerPath = (schema: SwaggerSchema) => {
	const server =
	schema.servers && Array.isArray(schema.servers)
	? schema.servers[0]
	: schema.host
	? [
	(schema.schemes && schema.schemes[0]) || 'http',
	'://',
	schema.host,
	schema.basePath,
	]
	.filter(Boolean)
	.join('')
	: undefined;
	if (!server) {
	return undefined;
	}
	if (typeof server === 'string') {
	return server;
	}
	const { url, variables } = server;
	return variables
	? Object.keys(server.variables).reduce((acc, variableName) => {
	const variable = server.variables[variableName];
	const value =
	typeof variable === 'string'
	? variable
	: variable.default || variable.enum[0];
	return acc.replace(`{${variableName}}`, value);
	}, url)
	: url;
	};

The basic support for openapi 3 and its path sections has been released in #143
#66 and #60 are enhancements that can be picked up later.
