passport-auth-token

Passport strategy for authenticating with an authentication token.

This module lets you authenticate using a token in your Node.js applications. It is based on passport-local module by Jared Hanson. By plugging into Passport, token authentication can be easily and unobtrusively integrated into any application or framework that supports Connect-style middleware, including Express.

Install

$ npm install passport-auth-token

Usage

Configure Strategy

The token authentication strategy authenticates users using a token. The strategy requires a verify callback, which accepts these credentials and calls done providing a user. Here is the pseudo code.

passport.use('authtoken', new AuthTokenStrategy(
  function(token, done) {
    AccessToken.findOne({
      id: token
    }, function(error, accessToken) {
      if (error) {
        return done(error);
      }

      if (accessToken) {
        if (!token.isValid(accessToken)) {
          return done(null, false);
        }

        User.findOne({
          id: accessToken.userId
        }, function(error, user) {
          if (error) {
            return done(error);
          }

          if (!user) {
            return done(null, false);
          }

          return done(null, user);
        });
      } else {
        return done(null);
      }
    });
  }
));

Authenticate Requests

Use passport.authenticate(), specifying the 'authtoken' strategy, to authenticate requests.

For example, as route middleware in an Express application:

app.post('/login',
  passport.authenticate(
    'authtoken',
    {
      session: false,
      optional: false
    }
  ),
  function(req, res) {
    res.redirect('/');
  }
);

You can also set the parameter optional to true, so the same call can be both authenticated and not authenticated.
