A bridge between hapi and OAuth2orize

hapi-oauth2orize

A bridge between hapi8+ and OAuth2orize

OAuth2orize is an OAuth2 provider implemented as a middleware for express. Given that you are (presumably) using hapi, you will need a bridge to make it work in hapi land. Thus, hapi-oauth2orize.

Note, this documentation is somewhat out of date. This project is currently being brought into the present. The most useful things to look at are currently the documentation/examples for OAuth2orize and the OAuth2orize methods that are exposed by the plugin.

Usage

npm install hapi-oauth2orize --save

After this, the usage is similar to to using vanilla OAuth2orize, but with a couple of tweaks to ensure compatiblity with hapi (>=8.x.x series).

// Require the plugin in hapi
server.register(require('hapi-oauth2orize'), function (err) {
  console.log(err);
});

var oauth = server.plugins['hapi-oauth2orize'];

Disclaimer

The code below is extracted from a working, but incomplete project. It has not been secured, or even fully finished. However, along with the OAuth2orize docs, you should be able to create a working implementation of your own.

Implicit Grant Flow

oauth.grant(oauth.grants.token(function (client, user, ares, done) {
  server.helpers.insert('token', {
    client: client._id,
    principal: user._id,
    scope: ares.scope,
    created: Date.now(),
    expires_in: 3600
  }, function (token) {
    done(null, token._id, {expires_in: token.expires_in});
  });
}));

Authorization Code Exchange Flow

oauth.grant(oauth.grants.code(function (client, redirectURI, user, ares, done) {
  server.helpers.insert('code', {
    client: client._id,
    principal: user._id,
    scope: ares.scope,
    redirectURI: redirectURI
  }, function (code) {
    done(null, code._id);
  });
}));

oauth.exchange(oauth.exchanges.code(function (client, code, redirectURI, done) {
  server.helpers.find('code', code, function (code) {
    if (!code || client.id !== code.client || redirectURI !== code.redirectURI) {
      return done(null, false);
    }
    server.helpers.insert('refreshToken', {
      client: code.client,
      principal: code.principal,
      scope: code.scope
    }, function (refreshToken) {
      server.helpers.insert('token', {
        client: code.client,
        principal: code.principal,
        scope: code.scope,
        created: Date.now(),
        expires_in: 3600
      }, function (token) {
        server.helpers.remove('code', code._id, function () {
          done(null, token._id, refreshToken._id, {expires_in: token.expires_in});
        });
      });
    });
  });
}));

oauth.exchange(oauth.exchanges.refreshToken(function (client, refreshToken, scope, done) {
  server.helpers.find('refreshToken', refreshToken, function (refreshToken) {
    if (refreshToken.client !== client._id) {
      return done(null, false, { message: 'This refresh token is for a different client'});
    }
    scope = scope || refreshToken.scope;
    server.helpers.insert('token', {
      client: client._id,
      principal: refreshToken.principal,
      scope: scope,
      created: Date.now(),
      expires_in: 3600
    }, function (token) {
      done(null, token._id, null, {expires_in: token.expires_in});
    });
  });
}));

// Client Serializers
oauth.serializeClient(function (client, done) {
  done(null, client._id);
});

oauth.deserializeClient(function (id, done) {
  server.helpers.find('client', id, function (client) {
    done(null, client[0]);
  });
});

OAuth Endpoints

server.route([{
    method: 'GET',
    path: '/oauth/authorize',
    handler: authorize
},{
    method: 'POST',
    path: '/oauth/authorize/decision',
    handler: decision
},{
    method: 'POST',
    path: '/oauth/token',
    handler: token
}]);

function authorize(request, reply) {
  oauth.authorize(request, reply, function (req, res) {
    reply.view('oauth', {transactionID: req.oauth2.transactionID});
  }, function (clientID, redirect, done) {
    server.helpers.find('client', clientID, function (docs) {
      done(null, docs[0], docs[0].redirect_uri);
    });
  });
};

function decision(request, reply) {
    oauth.decision(request, reply);
};

function token(request, reply) {
  oauth.authorize(function (clientID, redirect, done) {
    done(null, clientID, redirect);
  });
};
