This is the Swagger javascript client for use with swagger enabled APIs. It's written in javascript and tested with mocha, and is the fastest way to enable a javascript client to communicate with a swagger-enabled server.

The goal of Swagger™ is to define a standard, language-agnostic interface to REST APIs which allows both humans and computers to discover and understand the capabilities of the service without access to source code, documentation, or through network traffic inspection. When properly defined via Swagger, a consumer can understand and interact with the remote service with a minimal amount of implementation logic. Similar to what interfaces have done for lower-level programming, Swager removes the guesswork in calling the service.

Check out Swagger-Spec for additional information about the Swagger project, including additional libraries with support for other languages and more.

Install swagger-client:

npm install swagger-client

Then let swagger do the work!

var client = require("swagger-client")

var swagger = new client.SwaggerClient({
  url: 'http://petstore.swagger.wordnik.com/v2/swagger.json',
  success: function() {
    swagger.apis.pet.getPetById({petId:1});
  }
});

That's it! You'll get a JSON response with the default callback handler:

{
  "id": 1,
  "category": {
    "id": 2,
    "name": "Cats"
  },
  "name": "Cat 1",
  "photoUrls": [
    "url1",
    "url2"
  ],
  "tags": [
    {
      "id": 1,
      "name": "tag1"
    },
    {
      "id": 2,
      "name": "tag2"
    }
  ],
  "status": "available"
}

Need to pass an API key? Configure one as a querystring:

client.authorizations.add("apiKey", new client.ApiKeyAuthorization("api_key","special-key","query"));

...or with a header:

client.authorizations.add("apiKey", new client.ApiKeyAuthorization("api_key","special-key","header"));

Download swagger-client.js and shred.bundle.js into your lib folder

<script src='lib/shred.bundle.js' type='text/javascript'></script>
<script src='lib/swagger-client.js' type='text/javascript'></script>
<script type="text/javascript">
  // initialize swagger, point to a resource listing
  window.swagger = new SwaggerClient({
    url: "http://petstore.swagger.wordnik.com/api/api-docs",
    success: function() {
      // upon connect, fetch a pet and set contents to element "mydata"
      swagger.apis.pet.getPetById({petId:1}, function(data) {
        document.getElementById("mydata").innerHTML = JSON.stringify(data.obj);
      });
    }
  });

</script>

var pet = {
  id: 100,
  name: "dog"};

swagger.apis.pet.addPet({body: pet});

var pet = "<Pet><id>2</id><name>monster</name></Pet>";

swagger.apis.pet.addPet({body: pet}, {requestContentType:"application/xml"});

swagger.apis.pet.getPetById({petId:1}, {responseContentType:"application/xml"});

You can easily write your own request signing code for Swagger. For example:

var CustomRequestSigner = function(name) {
  this.name = name;
};

CustomRequestSigner.prototype.apply = function(obj, authorizations) {
  var hashFunction = this._btoa;
  var hash = hashFunction(obj.url);

  obj.headers["signature"] = hash;
  return true;
};

In the above simple example, we're creating a new request signer that simply base 64 encodes the URL. Of course you'd do something more sophisticated, but after encoding it, a header called signature is set before sending the request.

The swagger javascript client reads the swagger api definition directly from the server. As it does, it constructs a client based on the api definition, which means it is completely dynamic. It even reads the api text descriptions (which are intended for humans!) and provides help if you need it:

s.apis.pet.getPetById.help()
'* petId (required) - ID of pet that needs to be fetched'

The HTTP requests themselves are handled by the excellent shred library, which has a ton of features itself. But it runs on both node and the browser.
