Swagger Parser v3.4

Swagger 2.0 parser and validator for Node and browsers

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);
  });
