# Passport-Dropbox-OAuth2
[Passport](http://passportjs.org/) strategy for authenticating with [Dropbox](https://dropbox.com/)
using the OAuth 2.0 API.

This module lets you authenticate using Dropbox in your Node.js applications.
By plugging into Passport, Dropbox authentication can be easily and
unobtrusively integrated into any application or framework that supports
[Connect](http://www.senchalabs.org/connect/)-style middleware, including
[Express](http://expressjs.com/).

## Install
    $ npm install passport-dropbox-oauth2

## Usage
### Configure Strategy

The Dropbox authentication strategy authenticates users using a Dropbox account
and OAuth 2.0 tokens.  The strategy requires a `verify` callback, which accepts
these credentials and calls `done` providing a user, as well as `options`
specifying a API version, client ID, client secret, and callback URL. The library
defaults to version 1 of Dropbox's API.

    passport.use(new DropboxOAuth2Strategy({
        apiVersion: '2',
        clientID: DROPBOX_CLIENT_ID,
        clientSecret: DROPBOX_CLIENT_SECRET,
        callbackURL: "https://www.example.net/auth/dropbox-oauth2/callback"
      },
      function(accessToken, refreshToken, profile, done) {
        User.findOrCreate({ providerId: profile.id }, function (err, user) {
          return done(err, user);
        });
      }
    ));

### Authenticate Requests
Use `passport.authenticate()`, specifying the `'dropbox-oauth2'` strategy, to
authenticate requests.

For example, as route middleware in an [Express](http://expressjs.com/)
application:

    app.get('/auth/dropbox',
      passport.authenticate('dropbox-oauth2'));

    app.get('/auth/dropbox/callback', 
      passport.authenticate('dropbox-oauth2', { failureRedirect: '/login' }),
      function(req, res) {
        // Successful authentication, redirect home.
        res.redirect('/');
      });
