For the Browser

Installation

$ bower install sails.io.js

Basic Usage

    <!-- .... -->
  </body>
  <script type="text/javascript" src="./path/to/bower_components/sails.io.js"></script>
  <script type="text/javascript">
  
    // `io` is available as a global.
    // `io.socket` will connect automatically, but it is not ready yet (think of $(document).ready() from jQuery).
    // Fortunately, this library provides an abstraction to avoid this issue.
    // Requests you make before `io` is ready will be queued and replayed automatically when the socket connects.
    // To disable this behavior or configure other things, you can set properties on `io`.
    // You have one cycle of the event loop to change `io` settings before the auto-connection behavior starts.
    
    io.socket.get('/hello', function serverResponded (body, sailsResponseObject) {
      
      // body === sailsResponseObject.body
      console.log('Sails responded with: ', body);
      console.log('with headers: ', sailsResponseObject.headers);
      console.log('and with status code: ', sailsResponseObject.statusCode);
    });
  </script>
</html>

========================================

For Node.js

Why would I use this from a Node script?

Most commonly, this SDK is useful on the backend when writing tests. However, any time you'd want to use a WebSocket or Socket.io client from Node to talk to a Sails server, you can use this module to allow for the ordinary usage you're familiar with in the browser-- namely using the socket interpreter to simulate HTTP over WebSockets.

Installation

$ npm install socket.io-client
$ npm install sails.io.js

Basic Usage

var socketIOClient = require('socket.io-client');
var sailsIOClient = require('sails.io.js');

// Instantiate the socket client (`io`)
// (for now, you must explicitly pass in the socket.io client when using this library from Node.js)
var io = sailsIOClient(socketIOClient);

// Set some options:
// (you have to specify the host and port of the Sails backend when using this library from Node.js)
io.sails.url = 'http://localhost:1337';
// ...

// Send a GET request to `http://localhost:1337/hello`:
io.socket.get('/hello', function serverResponded (body, sailsResponseObject) {
  // body === sailsResponseObject.body
  console.log('Sails responded with: ', body);
  console.log('with headers: ', sailsResponseObject.headers);
  console.log('and with status code: ', sailsResponseObject.statusCode);
  
  // When you are finished with `io.socket`, or any other sockets you connect manually,
  // you should make sure and disconnect them, e.g.:
  io.socket.disconnect();
  
  // (note that there is no callback argument to the `.disconnect` method)
});

See the tests in this repository for more examples.
