cannot load partials or layout in hbs

I am facing some errors while integrating hbs and express in node js
content from layouts& partials are getting not loaded ,even though they are connected to
app.js , layout is loading when we move it into root of view.its not loading when its in a folder inside view.
When i move layouts.hbs to root it starts to load but partials are not loading since its inside a folder.(error:The partial my_partial could not be found)
when i googled about partial i found that hbs.registerPartial(path.join(__dirname, "/views/partials")); could be used but it showed an error that hbs.registerPartial is not a function.
so anyone please suggest me what to do
I expect solution for
How can i load default layout and partials by creating folders named layouts and partials respectively
-- views
-- partials
partial1.hbs
partial2.hbs
-- layouts
layout.hbs
app.js
error.hbs
//app.js
var createError = require('http-errors');

const hbs = require('express-handlebars');
var path = require('path');

app.use('/users', usersRouter);
// catch 404 and forward to error handler
app.use(function (req, res, next) {
next(createError(404));
});
// error handler
app.use(function (err, req, res, next) {
// set locals, only providing error in development
res.locals.message = err.message;
res.locals.error = req.app.get('env') === 'development' ? err : {};
// render the error page
res.status(err.status || 500);
res.render('error');
});

How can I serve the html, css, and js all while keeping the routes inside a module.export in a different file? Right now only html is served

I am a newbie to use express and as a result am bungling my way through making this web app.
I have my routes in a different file called route.js inside a module.export, and I manage all this inside app.js and I want to be able to serve a HTML page and keep it in the module. I've done so using sendFile but it doesn't serve the CSS and JS as well. What can I do to fix this?
app.js

var index = require('./routes/index');
var users = require('./routes/users');
var app = express();
var port = process.env.PORT || 3000;

}

You want to use a view engine and a static directory. You have some of the code already.
Your view engine using .ejs:
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'ejs');
And you can define your static and specify a path prefix:
app.use('/assets', express.static(path.join(__dirname, 'public')));
In your views directory, put your htmls with .ejs extension, such as timesheet.ejs. You can then create an assets directory for your css/js/image files and reference them in your timesheet.ejs using /assets/style.css.
Finally, in your route, you'll want to render the template:
res.render('timesheet')

use route middleware with handlebars in nodejs

The common middle for expressjs is the Route() middleware, but now I'm dropping jade and using handlebars. Handlebars itself have it ways to define the route. Because of that I may mess up my controllers inside my app.js.
Below is my app.js, any idea how can I split the route to a new file?
var express = require('express');
var app = express();
var exphbs = require('express-handlebars');
app.engine('handlebars', exphbs({defaultLayout: 'main'}));
app.set('view engine', 'handlebars');
app.get('/',function(req,res){
res.render('index');
});
var port = Number(process.env.PORT || 3000);
app.listen(port);

Something like this?
//exported routes in ./routes/index.js
var routes = require('./routes');
//invoke routes
routes(app);
and routes file
module.exports = function(app) {
app.post('/etc', function(req,res) {
/* do route stuff */
});
/* other stuff goes here */
}

Angular ng-view not working with express

I'm trying work open page home of directory partials/home using ng-view and ng-view not working with express. A new page opens with render when acess http://localhost:3000/home. All routes defined for angular has no effect. I would like to know how to render my page partials/home.html in index.html using ng-view with express.
app.js
//módulos
var express = require('express');
var load = require('express-load');
var bodyParser = require('body-parser');
var app = express();
var path = require('path');
var favicon = require('serve-favicon');
var logger = require('morgan');
var cookieParser = require('cookie-parser');
var server = require('http').Server(app);
var io = require('socket.io')(server);
// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.engine('html', require('ejs').renderFile);
app.set('view engine', 'html');
//uncomment after placing your favicon in /public
app.use(favicon(__dirname + '/public/favicon.ico'));
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({
extended: false
}));
app.use(cookieParser());
app.use(express.static(path.join(__dirname, 'public')));
load('routes').then('controllers').into(app);
server.listen(3000);
console.log('Site no ar ...');
module.exports = app;
Routes Express - index.js
module.exports = function (app) {
app.get('/', function(req, res){
res.render('index');
});
app.get('/:name', function(req, res){
var name = req.params.name;
res.render('partials/' + name);
});
app.get('*', function(req, res){
res.render('index');
});
};
Routes Angular - Location: public/app/app.js
var app = angular.module('appSiteFio',['ngRoute']);
app.config(function($routeProvider, $locationProvider){
// remove o # da url
$locationProvider.html5Mode(true);
$routeProvider
.when('/', {
templateUrl : 'index.html',
controller : 'mainController',
})
.when('/home', {
templateUrl : 'partials/home.html',
controller : 'homeController',
})
.otherwise ({ redirectTo: '/' });
});

I would suggest changing the index.js file to something like:
module.exports = function (app) {
app.use(express.static('/partials')); //here you can write your partials directory.
app.get('*', function(req, res){
res.render('index');
});
};
(Also change your templateUrl inside angular file with the partials prefix.);
that way angular will allways will be loaded and angular router will deal with all the views fetching from the static partials folder

app.configure(function){} typeerror undefined is not a function

i am creating a chat application using socket.io and angularjs, when i run the app.js file using cmd, i get an error saying "app.configure(function){} typeerror undefined is not a function"
what could be the problem?
my code looks like this:
var http = require('http');
var express = require('express'),
routes = require('./routes'),
socket = require('./routes/socket.js');
app = module.exports.app = express();
var server = http.createServer(app);
var io = require('socket.io').listen(server); //pass a http.Server instance
server.listen(80);
// Configuration
app.configure(function(){
app.set('views', __dirname + '/views');
app.set('view engine', 'jade');
app.set('view options', {
layout: false
});
app.use(express.bodyParser());
app.use(express.methodOverride());
app.use(express.static(__dirname + '/public'));
app.use(app.router);
});

i was using Express 4.0 in which configure was removed. See http://expressjs.com/guide/migrating-4.html#other-changes
Simple mistake took me an hour to realise.
