Features

  • Parses Swagger specs in JSON or YAML format
  • Validates against the Swagger 2.0 schema or OpenAPI 3.0 Schema
  • Resolves all $ref pointers, including external files and URLs
  • Can bundle all your Swagger files into a single file that only has internal $ref pointers
  • Can dereference all $ref pointers, giving you a normal JavaScript object that's easy to work with
  • Tested in Node.js and all modern web browsers on Mac, Windows, and Linux
  • Tested on over 1,500 real-world APIs from Google, Instagram, Spotify, etc.
  • Supports circular references, nested references, back-references, and cross-references
  • Maintains object reference equality — $ref pointers to the same value always resolve to the same object instance

Example

SwaggerParser.validate(myAPI, (err, api) => {
  if (err) {
    console.error(err);
  }
  else {
    console.log("API name: %s, Version: %s", api.info.title, api.info.version);
  }
});

Or use async/await or Promise syntax instead. The following example is the same as above:

try {
  let api = await SwaggerParser.validate(myAPI);
  console.log("API name: %s, Version: %s", api.info.title, api.info.version);
}
catch(err) {
  console.error(err);
}

For more detailed examples, please see the API Documentation

Installation

Install using npm:

npm install swagger-parser

Usage

When using Swagger Parser in Node.js apps, you'll probably want to use CommonJS syntax:

const SwaggerParser = require("swagger-parser");

When using a transpiler such as Babel or TypeScript, or a bundler such as Webpack or Rollup, you can use ECMAScript modules syntax instead:

import SwaggerParser from "swagger-parser";

Browser support

Swagger Parser supports recent versions of every major web browser. Older browsers may require Babel and/or polyfills.

To use Swagger Parser in a browser, you'll need to use a bundling tool such as Webpack, Rollup, Parcel, or Browserify. Some bundlers may require a bit of configuration, such as setting browser: true in rollup-plugin-resolve.
