how to load in angularJS page with node - node.js

I am working on a single page web app with node/angular and jade. I am fairly new to angular, and I wanted to know what I have to do with my app.js file so that my first page template loads from my angular file rather than from my jade template.
I structured my files as such:
public/
index.html
javascript/
img/
stylesheets/
routes/
index.js
views/
partials/
a.jade
b.jade
app.js
This is what my app.js looks like:
var express = require('express');
var routes = require('./routes');
var user = require('./routes/user');
var http = require('http');
var path = require('path');
var app = express();
// all environments
app.set('port', process.env.PORT || 3000);
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'jade');
app.use(express.favicon());
app.use(express.logger('dev'));
app.use(express.json());
app.use(express.urlencoded());
app.use(express.methodOverride());
app.use(app.router);
app.use(express.static(path.join(__dirname, 'public')));
app.use(express.cookieParser('cookies monster')); // Cookie secret
// development only
if ('development' == app.get('env')) {
app.use(express.errorHandler());
}
/*
* Views
*/
app.get('/', routes.index);
app.get('/a', routes.a);
app.get('/b', routes.b);
http.createServer(app).listen(app.get('port'), function(){
console.log('Express server listening on port ' + app.get('port'));
});
My index.js looks like this:
exports.index = function(req, res){
res.render('index', { title: 'Test Application' });
};
// View A
exports.a = function(req, res) {
res.render('partials/a', { layout: false, test: 'LOL' });
};
// View B
exports.b = function(req, res) {
res.render('partials/b', { layout: false, test: 'YOLO' });
};
When I run this, It does not use the index.html as the first page. How would I go about doing so, so that the initial page template is actually the index.html? I can't seem to find the answer anywhere.

You could return the actual index.html file from your router.
app.get('/', function(req, res, next){
return res.sendfile(app.get('public') + '/index.html');
});
I should note that I also put app.set('public', path.join(__dirname, 'public')); inside app.js for easy access to the public directory.

Express catch all route excluding static content such as css and js

New to Node.js.
I'm using the VS2015 Express 3 template. How can I write my routing to:
Have a page at "/"
Have a a catch all route that responds with the home page "/"
Doesn't interfere with JS and CSS files
I.e., I tried the following, but then the JS and CSS files in the public directory respond with 404 don't render or execute. I thought that the static files code would handle it, but it does not. It works until I add the block with "*".
var express = require('express');
var routes = require('./routes');
var http = require('http');
var path = require('path');
var app = express();
// all environments
app.set('port', process.env.PORT || 3000);
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'jade');
app.use(express.favicon());
app.use(express.logger('dev'));
app.use(express.json());
app.use(express.urlencoded());
app.use(express.methodOverride());
app.use(app.router);
app.use(require('stylus').middleware(path.join(__dirname, 'public')));
app.use(express.static(path.join(__dirname, 'public')));
// development only
if ('development' == app.get('env')) {
app.use(express.errorHandler());
}
app.get('/', routes.index);
app.get('*', function (req, res) {
res.send('/', 404);
});
http.createServer(app).listen(app.get('port'), function () {
console.log('Express server listening on port ' + app.get('port'));
});
The solution, as suggested by jfriend00, is to add the following line below app.get('/', routes.index):
app.use(routes.index);

app.post not working node.js

I am new to node and I wanted to try a simple app.post but I can't get it to work. my app.js and index.jade code is shown below. I am trying to get my app to print "hi" to the console when I enter data in the form and press submit but this is not happening.
**app.js**
/**enter code here
* Module dependencies.
*/
var express = require('express');
var routes = require('./routes');
var user = require('./routes/user');
var http = require('http');
var path = require('path');
var app = express.createServer();
app.use(express.bodyParser());
// all environments
app.set('port', process.env.PORT || 3000);
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'jade');
app.use(express.favicon());
app.use(express.logger('dev'));
app.use(express.json());
app.use(express.urlencoded());
app.use(express.methodOverride());
app.use(app.router);
app.use(express.static(path.join(__dirname, 'public')));
// development only
if ('development' == app.get('env')) {
app.use(express.errorHandler());
}
app.get('/', routes.index);
app.get('/users', user.list);
app.get('/george', function(req,res){
res.send('This is the random george page');
console.log("george");
});
app.get('/second', function(req,res){
res.render('secondpage');
});
app.get('/act', function(request, response){
console.log("hello");
});
app.post('/', function(request, response){
console.log("hi");
});
app.listen(3000);
console.log("Express server listening on port 3000");
**index.jade**
extends layout
block content
h1: a(href = 'second') George
p Welcome to your demosite George
form(method="post", action="/", name="act")
p
|Username
input(type="text", name="user")
p
|Password
input(type="text", name="pass")
p
input(type="submit", value="Submit")
First guess is everything in your jade file after the form tag needs 2 more leading spaces indent to make sure the input tags end up nested inside the form tag in the HTML. Your express JS code looks like it should work then.

Using piler with express 3 and nodejs

I want to run Express 3.3.x with its default implementation.
Express uses its routes module, so what I have to do, if JS and CSS is accessible by any view in any route?
/**
* Module dependencies.
*/
var express = require('express');
var http = require('http');
var path = require('path');
var piler = require('piler');
var mongoose = require('mongoose');
var config = require('./config');
var app = exports.app = express();
var js = piler.createJSManager();
var css = piler.createCSSManager();
var srv = require('http').createServer(app);
// all environments
js.bind(app,srv);
css.bind(app,srv);
app.set('port', process.env.PORT || 3000);
app.set('views', __dirname + '/views');
app.set('view engine', 'jade');
app.use(express.favicon());
app.use(express.logger('dev'));
app.use(express.bodyParser());
app.use(express.methodOverride());
app.use(express.cookieParser('your secret here'));
app.use(express.session());
app.use(app.router);
app.use(require('less-middleware')({ src: __dirname + '/public' }));
app.use(express.static(path.join(__dirname, 'public')));
js.addUrl("http://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.js");
// development only
if ('development' == app.get('env')) {
app.use(express.errorHandler());
}
/**
* Routes
*/
var routes = require('./routes');
app.get('/', routes.index);
srv.listen(app.get('port'), function(){
console.log('Express server listening on port ' + app.get('port'));
});
In the example of piler:
app.get("/", function(req, res){
res.render("index.jade", {
layout: false,
js: js.renderTags(),
css: css.renderTags()
});
});
This works. But I have
app.get('/', routes.index);
So what I have to do, that js.renderTags() works in every view?
If you are trying to pass variables to render, you can use res.locals
app.use(function(req,res,next){
res.locals.layout= false;
res.locals.js= js.renderTags();
res.locals.css= css.renderTags();
next();
});
Use this before your router but don't overwrite your locals (res.locals={...})

how do i fix routes to find views inside subfolders in node.js

i am trying to create a route for localhost:port/admin/
and i want to keep the routes.js files and view.js files in matching folders so i wont have too much spaggeti later on
but i keep getting: 500 Error: Failed to lookup view "/admin/manage_subjects"
for trying to create a new route and using same folders few the same
i have the following view folder with express
mainapp(root)
routes(folder)
admin(folder)
index.js(nested inside admin)
index.js(nested inside routes)
views(folder)
admin(folder)
admin_layout.jade(nested inside admin)
manage_subjects.jade(nested inside admin)
index.jade(nested inside views)
layout.jade(nested inside views)
code:
routes/admin/index.js
exports.index = function (req, res) {
res.render('manage_subjects',{title:'Express'});}
views/admin/manage_subjects.jade
extends admin_layout
block content
h1 = title
p Welcome to #{title}
my app.js code
/**
* Module dependencies.
*/
var express = require('express')
, routes = require('./routes')
, admin_routes = require('./routes/admin/')
, user = require('./routes/user')
, http = require('http')

var app = express();

app.use(express.favicon());
app.use(express.logger('dev'));
app.use(express.bodyParser());
app.use(express.methodOverride());
app.use(app.router);
app.use(express.static(path.join(__dirname, 'public')));
// development only
if ('development' == app.get('env')) {
app.use(express.errorHandler());
}
//fill local subjects
repository.subjects.GetAll(function (err, data) {
if (err) throw err;
app.locals.subjects = data;
});
//append routes
app.get('/', routes.index);
app.get('/admin', admin_routes.index);
app.get('/users', user.list);
http.createServer(app).listen(app.get('port'), function(){
console.log('Express server listening on http://localhost:' + app.get('port'));
});
I've been dealing with what I think is the same problem and figured out how to fix it. So in case someone else comes across this problem I'm posting my solution.
So here is what I had that was causing 404's and 500's
app.js
var routes = require('./routes/index');
var admin = require('./routes/admin');
app.use('/', routes);
app.use('/admin', admin);
and here was my routes/index.js
//append routes
var express = require('express');
var router = express.Router();
router.get('/', function(req, res) {
res.render('index', {title: 'Express'});
});
module.exports = router;
and my routes/admin.js:
var express = require('express');
var router = express.Router();
router.get('/admin', function(req, res) {
res.render('admin/index', {title: 'Express'});
});
module.exports = router;
by defining the second /admin inside the router.get() function I think I was effectively telling node to look for the html in my views folder under the following path views/admin/admin/index.ejs. So to fix that all I had to do was remove either the /admin from the router.get() or the /admin from the app.use()
So my working code now looks like this:
app.js
var routes = require('./routes/index');
var admin = require('./routes/admin');
app.use('/', routes);
app.use('/admin', admin); //I left the /admin here and instead removed the one in routes/admin.js
and here was my routes/index.js
//append routes
var express = require('express');
var router = express.Router();
router.get('/', function(req, res) {
res.render('index', {title: 'Express'});
});
module.exports = router;
and my routes/admin.js:
var express = require('express');
var router = express.Router();
router.get('/', function(req, res) { //NOTICE THE CHANGE HERE
res.render('admin/index', {title: 'Express'});
});
module.exports = router;
So making that change made it so I could have sub folders in my views folder.
Simple Answer for sub-folders inside the views folder (mine is called frontend)
click here the picture to see the folder structure
file app.js
app.set('views', [path.join(__dirname, 'frontend'), path.join(__dirname, 'frontend/locked'), path.join(__dirname, 'frontend/template'), path.join(__dirname, 'frontend/public')]);
app.set('view engine', 'pug')
I'd check out TJ's video on Modular apps on his vimeo the best part about this work flow is your code becomes really flexible and it's alot easier to stay DRY.
Additionally I would do something like this with my app.set("views")
var path = require("path");
app.set('views', path.join(__dirname, 'views'));
// you can then extend this to the example for routes
Another alternative would be something like in your app.js file:
var express require("express")
var app = express()
var routes = require("./path/to/routes")(app)
and then routes would look like:
routes = function (app) {
app.get("/route", middleWareifYou.gotIt, route.handler || function (req, res) {
res.send("some msg");
});
};
module.exports = routes
Cheers, I hope this helps!
I had a similar problem and what worked for me was setting the views folder in both the main app file and in the router file too.
So in the main app.js file I had:
app.set('views', viewsFolderPath);
And inside my router.js file I also did the same thing:
app.set('views', viewsFolderPath);

node.js/angular.js - Cannot GET

I have the root route and it works fine. I also have a another route 127.0.0.1:3000/dashboard if I just type that url into the address bar I get this error:
Cannot GET /dashboard
If I create a link to the same url it works fine.
If I then refresh that page I get the same error again.
Below is my node.js route

});
app.configure('development', function(){
app.use(express.errorHandler({ dumpExceptions: true, showStack: true }));

Angular route
'use strict';
angular.module('myApp', ['myApp.filters', 'myApp.services', 'myApp.directives']).
config(['$routeProvider', '$locationProvider', function($routeProvider, $locationProvider) {
$routeProvider.
when('/', {
templateUrl: 'partials/landing',
controller: LandingCtrl
}).
when('/dashboard', {
templateUrl: 'partials/dashboard',
controller: DashboardCtrl
}).
otherwise({
redirectTo: '/'
});
$locationProvider.html5Mode(true);
}]);
The reason this does not work is that your server is not catching all other routes and routing them to your single page app which is served by routes.index.
In order to catch all other routes and route them to the index page so that your angular app can see if it matches the supplied url all you need to do is add the following line after your last route is declared:
app.get('*', routes.index);
Now you should be able to:
navigate directly to a url served by your Angular.js app
refresh any page without error

In a nutshell:
npm install --save-dev connect-modrewrite
Gruntfile:
connect: {
options: {
// ...
// Modrewrite rule, connect.static(path) for each path in target's base
middleware: function (connect, options) {
var optBase = (typeof options.base === 'string') ? [options.base] : options.base;
return [require('connect-modrewrite')(['!(\\..+)$ / [L]'])].concat(
optBase.map(function(path){ return connect.static(path); }));
}
}
}
Route app.get('/index/dashboard', routes.dashboard); refers to http://hostname/index/dashboard whereas when('/dashboard', { ... }) refers to http://hostname/dashboard.
You should correct the route: app.get('/dashboard', routes.dashboard);
I'd suggest a pretty fast javascript solution in front and back end.
NodeJs
// set up our one route to the index.html file
app.get('*', function (req, res){
res.sendFile(path.join(__dirname+'/public/index.html'));
});
This code tells to de local/remote server where is the main html, so it could find the rest of templates.
AngularJs
// If 404 Redirect to home
$routeProvider.otherwise( { redirectTo: '/'} );
This is also really helpful, so never goes to a missing page.
