Swagger/OpenAPI Parser

Swagger 2.0 and OpenAPI 3.0 parser and validator for Node and browsers

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 1,000 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, 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);
  });
