openapi-parse

Basic parser for OpenAPI specs. This is a thin wrapper around existing libraries. If you need more power/flexibility, check out Swagger/OpenAPI Parser, JSON Schema $Ref Parser, or swagger2openapi.

Installation

npm i openapi-parse

or

yarn add openapi-parse

Usage

import parse from 'openapi-parse'
// or const parse = require('openapi-parse').default
 
const options = { ... }
const specPathOrSchemaObject = ... // specify Swagger/OpenAPI spec path or a loaded schema object
 
const result = await parse(options)(specPathOrSchemaObject)

Options

Option	Default Value	Description
basePath	null	Used as the base path for relative references within the spec.
dereference.mode	['none']	Set to an array of dereference modes. Possible mode values are none (no references will be dereferenced), external (only external references will be dereferenced), and all (both external and internal references will be dereferenced). The result will be an array of schemas, one for each mode specified.
dereference.resolve	(original, result) => result[0]	After dereferencing, the result collection is passed to the specified resolve function. The resolve function also receives the original loaded schema, the return value will be used as the final dereferenced schema.
upgrade.enabled	false	If enabled, OpenAPI 2.0 specs will be automatically upgraded to OpenAPI 3.0 using swagger2openapi.
upgrade.options	{}	These options are passed down to swagger2openapi. More info.
parser.canParse	fileInfo => false	Receives { path, extension, data } about referenced content. You can override and return true if you can parse the provided file information. More info.
parser.parse	async fileInfo => {}	Receives { path, extension, data } about referenced content. You can override to implement a parser for the specified content. More info.
resolver.canResolve	fileInfo => false	Receives { path, extension } about referenced content. You can override and return true if you are able to resolve the path. More info.
resolver.resolve	async fileInfo => {}	Receives { path, extension } about referenced content. You can override to implement a resolver for the specified content. More info.
