swagger.js

swagger.js is a javascript client for use with swaggering APIs. It's written in CoffeeScript and tested with Jasmine.

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

Usage

Point swagger.js at a resource discovery file like api.wordnik.com/v4/resources.json and it builds itself at runtime.

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<script type="text/javascript" src="https://raw.github.com/wordnik/swagger.js/master/lib/swagger.js"></script>
<script type="text/javascript">
  $(function() { 
    window.wordnik = new SwaggerApi({
      discoveryUrl: "http://api.wordnik.com/v4/resources.json",
      apiKey: "MY_API_KEY",
      success: function() {
        console.log('Shall we dance?');
      }
    });
  });
</script>

How it Works

  1. Fork the repo.
  2. Clone it.
  3. Open spec.html in your browser.
  4. Follow along in the Javascript console.

Initialization

wordnik = new SwaggerApi({
  api_key: 'YOUR_API_KEY', // Don't have a Wordnik API key? Get one at developer.wordnik.com
  verbose: true,
  success: function() { console.log("Your client is ready to swagger."); }
});

When initializing a swagger.js SwaggerApi class, the default discoveryUrl is http://api.wordnik.com/v4/resources.json, so we skipped it above.

After executing the above code you should see the success message in your console.

Object Hierarchy

Now you have access to an object called wordnik. This object is what swagger.js builds at runtime when you point it at a discoveryUrl. Try exploring it in the console:

wordnik
wordnik.resources
wordnik.resources.word.operations
wordnik.resources.word.operations.getDefinition

Quick Reference

You also get some console help() methods for quick reference. Some examples:

// Apis
wordnik.help()

// Resources
wordnik.resource.word.help()

// Operations
wordnik.resources.word.operations.getExamples.help()

Making Requests

There are two ways to make a request:

// shorthand form
wordnik.word.getDefinitions(args, callback);

// longhand form
wordnik.resources.word.operations.getDefinitions.do(args, callback);

// example usage
wordnik.word.getDefinitions({word: 'bliss'}, function(definitions) {
  console.log(definitions);
})

Request Headers

You can include your own headers in the args object:

args = {word: 'swole', limit:5}
args.headers = {magic: 'potion'}
callback = function(examples) { console.log(examples); }
wordnik.word.getExamples(args, callback);

If you want to initialize the Request without actually firing off a network request you can set a header called mock with any value.

Request Body

For GETs and POSTs, you can include the request body in the args object:

args = {}
args.body = {name: "gizmo", description: "A thing that does stuff."}
callback = function(thing) { console.log(thing); }
myApi.things.createThing(args, callback);

Debugging / cURL

Set verbose to true when initializing your client to see cURL equivalents of your requests in the browser console, complete with headers:

wordnik = new SwaggerApi({
  api_key: 'YOUR_API_KEY',
  verbose: true,
  success: function() {
    args = {
      word: 'dog'
      headers: {fubar: 'maybe'}
    }
    wordnik.word.getDefinitions.do(args, function(definitions){
      console.log(definitions[0].word);
      for (var i = 0; i < definitions.length; i++) {
        var definition = definitions[i];
        console.log(definition.partOfSpeech + ": " + definition.text);
      }
    });
  }
});

// Console output:
// curl --header "fubar: maybe" http://api.wordnik.com/v4/word.json/dog/definitions?api_key=YOUR_API_KEY
// dog
// noun: A domesticated carnivorous mammal (Canis familiaris) related to the foxes and wolves and raised in a wide variety of breeds.
// noun: Any of various carnivorous mammals of the family Canidae, such as the dingo.
// noun: A male animal of the family Canidae, especially of the fox or a domesticated breed.
// etc...

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.

open http://nodejs.org/#download 
npm install -g coffee-script
# The 'dev' cake 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.
