Swagger 2.0 and OpenAPI 3.0 parser/validator

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, Microsoft, Facebook, 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

1SwaggerParser.validate(myAPI, (err, api) => {
2  if (err) {
3    console.error(err);
4  }
5  else {
6    console.log("API name: %s, Version: %s", api.info.title, api.info.version);
7  }
8});

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

1try {
2  let api = await SwaggerParser.validate(myAPI);
3  console.log("API name: %s, Version: %s", api.info.title, api.info.version);
4}
5catch(err) {
6  console.error(err);
7}

Installation

Install using npm:

1npm install @teamteanpm2024/optio-temporibus-delectus

Usage

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

1const SwaggerParser = require("@teamteanpm2024/optio-temporibus-delectus");

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

1import * as SwaggerParser from '@teamteanpm2024/optio-temporibus-delectus';

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.
