Angular JS + Node JS + Passport + Spring OAuth2 Authentication/Authorization - angularjs

Question

I am new to PassportJS and AngularJS and I have a doubt about how to proceed with this authorization.
I have Spring REST API Secured by Oauth2, but I have to send together user credentials like this:
[http://localhost:8080/myapp/oauth/token]
grant_type=password&username=email&password=password&client_id=09e749d8309f4044&client_secret=189309492722aa5a&scope=read
In client my application I use passport and I want to authorize/authenticate my users, how can I create a Stratagy for this ?
I will send here my server config and my security Lib.
Server.js
var fs = require('fs');
var http = require('http');
var https = require('https');
var privateKey = fs.readFileSync(__dirname + '/cert/privatekey.pem').toString();
var certificate = fs.readFileSync(__dirname + '/cert/certificate.pem').toString();
var credentials = {key: privateKey, cert: certificate};
var express = require('express');
var config = require('./config.js');
var passport = require('passport');
var security = require('./lib/security');
var xsrf = require('./lib/xsrf');
var protectJSON = require('./lib/protectJSON');
require('express-namespace');
var app = express();
var secureServer = https.createServer(credentials, app);
var server = http.createServer(app);
// Serve up the favicon
app.use(express.favicon(config.server.distFolder + '/favicon.ico'));
// First looks for a static file: index.html, css, images, etc.
app.use(config.server.staticUrl, express.compress());
app.use(config.server.staticUrl, express['static'](config.server.distFolder));
app.use(config.server.staticUrl, function(req, res, next) {
res.send(404); // If we get here then the request for a static file is invalid
});
app.use(protectJSON);
app.use(express.logger()); // Log requests to the console
app.use(express.bodyParser()); // Extract the data from the body of the request - this is needed by the LocalStrategy authenticate method
app.use(express.cookieParser(config.server.cookieSecret)); // Hash cookies with this secret
app.use(express.cookieSession()); // Store the session in the (secret) cookie
app.use(passport.initialize()); // Initialize PassportJS
app.use(passport.session()); // Use Passport's session authentication strategy - this stores the logged in user in the session and will now run on any request
app.use(xsrf); // Add XSRF checks to the request
security.initialize(config.oauth.authorize_url, config.oauth.access_token, config.oauth.apiKey, config.oauth.secretKey, config.oauth.scopereq); // Add a Oauth strategy for handling the authentication
app.use(function(req, res, next) {
if ( req.user ) {
console.log('Current User:', req.user.firstName, req.user.lastName);
} else {
console.log('Unauthenticated');
}
next();
});
app.post('/login', security.login);
app.post('/logout', security.logout);
// Retrieve the current user
app.get('/current-user', security.sendCurrentUser);
// Retrieve the current user only if they are authenticated
app.get('/authenticated-user', function(req, res) {

});
// Retrieve the current user only if they are admin
app.get('/admin-user', function(req, res) {

// This route deals enables HTML5Mode by forwarding missing files to the index.html
app.all('/*', function(req, res) {
// Just send the index.html for other files to support HTML5Mode
res.sendfile('index.html', { root: config.server.distFolder });
});
// A standard error handler - it picks up any left over errors and returns a nicely formatted server 500 error
app.use(express.errorHandler({ dumpExceptions: true, showStack: true }));
// Start up the server on the port specified in the config
server.listen(config.server.listenPort, 'localhost', 511, function() {
// // Once the server is listening we automatically open up a browser
var open = require('open');
open('http://localhost:' + config.server.listenPort + '/');
});
console.log('Deengo Business App Server - listening on port: ' + config.server.listenPort);
secureServer.listen(config.server.securePort);

I do not know if I have to use passport-Bearer or not and how to use-it.
Thanks in advance for any help.

I do not know if I have to use passport-Bearer or not and how to use-it.
No. There are other options, such as:
oauth.io
httpProvider + express middleware
Here is an example of how to use passport:
// Express using passport-local
// This code is adaptation of examples/express3 from https://github.com/jaredhanson/passport-local
// configure Express
app.configure(function() {
// ...
app.use(express.session({
// The domain should start with a dot, as this allows the subdomain.
domain: '.app.local',
secret: 'keyboard cat'
}));
// Enable cors.
app.use(function(req, res, next) {
res.header('Access-Control-Allow-Credentials', true);
res.header('Access-Control-Allow-Origin', req.headers.origin);
res.header('Access-Control-Allow-Methods', 'GET,PUT,POST,DELETE');
res.header('Access-Control-Allow-Headers', 'X-Requested-With, X-HTTP-Method-Override, Content-Type, Accept');
next();
});
// ...
});
app.get('/account', ensureAuthenticated, function(req, res){
// Return the current user's info
res.json(req.user);
});
