Features
--------------------------
- Parses Swagger specs in **JSON** or **YAML** format
- Validates against the [Swagger 2.0 schema](https://github.com/OAI/OpenAPI-Specification/blob/master/schemas/v2.0/schema.json) or [OpenAPI 3.0 Schema](https://github.com/OAI/OpenAPI-Specification/blob/master/schemas/v3.0/schema.json)
- [Resolves](https://apitools.dev/swagger-parser/docs/swagger-parser.html#resolveapi-options-callback) all `$ref` pointers, including external files and URLs
- Can [bundle](https://apitools.dev/swagger-parser/docs/swagger-parser.html#bundleapi-options-callback) all your Swagger files into a single file that only has _internal_ `$ref` pointers
- Can [dereference](https://apitools.dev/swagger-parser/docs/swagger-parser.html#dereferenceapi-options-callback) all `$ref` pointers, giving you a normal JavaScript object that's easy to work with
- **[Tested](https://github.com/APIDevTools/swagger-parser/actions)** in Node.js and all modern web browsers on Mac, Windows, and Linux
- Tested on **[over 1,500 real-world APIs](https://apis.guru/browse-apis/)** from Google, Microsoft, Facebook, Spotify, etc.
- Supports [circular references](https://apitools.dev/swagger-parser/docs/#circular-refs), nested references, back-references, and cross-references
- Maintains object reference equality — `$ref` pointers to the same value always resolve to the same object instance

Example
--------------------------
```javascript
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](http://javascriptplayground.com/blog/2015/02/promises/) syntax instead. The following example is the same as above:
```javascript
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](https://apitools.dev/swagger-parser/docs/)
Installation
--------------------------
Install using [npm](https://docs.npmjs.com/about-npm/):
```bash
npm install @apidevtools/swagger-parser
```
Usage
--------------------------
When using Swagger Parser in Node.js apps, you'll probably want to use **CommonJS** syntax:
```javascript
const SwaggerParser = require("@apidevtools/swagger-parser");
```
When using a transpiler such as [Babel](https://babeljs.io/) or [TypeScript](https://www.typescriptlang.org/), or a bundler such as [Webpack](https://webpack.js.org/) or [Rollup](https://rollupjs.org/), you can use **ECMAScript modules** syntax instead:
```javascript
import * as SwaggerParser from '@apidevtools/swagger-parser';
```
Browser support
--------------------------
Swagger Parser supports recent versions of every major web browser. Older browsers may require [Babel](https://babeljs.io/) and/or [polyfills](https://babeljs.io/docs/en/next/babel-polyfill).
To use Swagger Parser in a browser, you'll need to use a bundling tool such as [Webpack](https://webpack.js.org/), [Rollup](https://rollupjs.org/), [Parcel](https://parceljs.org/), or [Browserify](http://browserify.org/). Some bundlers may require a bit of configuration, such as setting `browser: true` in [rollup-plugin-resolve](https://github.com/rollup/rollup-plugin-node-resolve).
API Documentation
--------------------------
Full API documentation is available [right here](https://apitools.dev/swagger-parser/docs/)
Security
--------------------------
The library, by default, attempts to resolve any files referenced using `$ref`, without considering file extensions or the location of the files. This can result in Local File Inclusion (LFI), thus, potentially sensitive information disclosure. Developers must be cautious when working with documents from untrusted sources. See [here](SECURITY.md) for more details and information on how to mitigate LFI.
