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

Find out more about the swagger project at swagger.wordnik.com, and follow us on Twitter at @swagger_doc.

See the swagger website or the swagger-core wiki, which contains information about the swagger json spec.

Calling an API with swagger + node.js!

Install swagger-client:

npm install swagger-client

Then let swagger do the work!

var client = require("swagger-client")

var swagger = new client.SwaggerApi({
  url: 'http://petstore.swagger.wordnik.com/api/api-docs',
  success: function() {
    if(swagger.ready === true) {
      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"));

Calling an API with swagger + the browser!

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

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

</script>

Need to send an object to your API via POST or PUT?

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

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

Sending XML in as a payload to your API?

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

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

Need XML response?

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

How does it work?

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.

Development

Please fork the code and help us improve swagger.js. Send us a pull request and we'll mail you a wordnik T-shirt!

Swagger.js is written in CoffeeScript, so you'll need Node.js and the CoffeeScript compiler. For more detailed installation instructions, see coffeescript.org/#installation.

# generate the javascript libraries and put them in the `lib` folder

npm run-script build

# The 'dev' task will:
# 1. Open source files in your $EDITOR
# 2. Open and run the Jasmine specs in your browser.
# 3. Watch for changes to CoffeeScript files and auto-compile them to Javascript.

npm run-script dev

# List all cake tasks:
