nforce-express
==============

[express.js](https://github.com/strongloop/express) plugin for
[nforce](https://github.com/kevinohara80/nforce). 
This plugin provides an express/connnect middleware factory that
automatically handles the OAuth 2.0 callback from Salesforce.

## Usage

Installation

```
npm install nforce nforce-express
```

```js
var nforce = require('nforce');

// load the plugin
require('nforce-express')(nforce);

var org = nforce.createConnection({
  clientId: '{{clientId}}',
  clientSecret: '{{clientId}}',
  redirectUri: 'http://localhost:3000/oauth/_callback',
  plugins: ['express']
});
```

Then when your express application is set up, you can load
the middleware. The middleware listens for OAuth callbacks from
a web server flow and will automatically complete the required
POST request for an `access_token`.

```js
// add the middleware to the stack
app.use(org.express.oauth({
  onSuccess: '/test/query',
  onError: '/oauth/error'
}));

// create a route to start the flow
app.get('/oauth/authorize', function(req, res){
  return res.redirect(org.getAuthUri());
});
```

The resulting OAuth object will be stored on the session. This means that
**you must be using sessions in your express app**!
