Features

  • Parses Swagger specs in JSON or YAML format
  • Validates against the Swagger 2.0 schema and the Swagger 2.0 spec
  • 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
  • Configurable caching of external files and URLs
  • Tested in Node, IO.js, and all modern web browsers on Mac, Windows, Linux, iOS, and Android
  • Tested on over 200 real-world APIs from Google, Instagram, Cisco, 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, function(err, api) {
  if (err) {
    console.error(err);
  }
  else {
    console.log("API name: %s, Version: %s", api.info.title, api.info.version);
  }
});

Or use Promises syntax instead. The following example is the same as above:

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

For more detailed examples, please see the API Documentation
