Hi I am trying display the message : respond with a resource from routes folder/user.js
exports.list = function (req, res) {
res.send("respond with a resource");
};
But I am getting an error 404 in command prompt.And in url
localhost:8080\user where the response is sent I get the message:
Cannot GET /user
my app.js has code:
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(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('/users', user.list);
http.createServer(app).listen(app.get('port'), function () {
console.log('Express server listening on port ' + app.get('port'));
});
The example I am working on is from https://www.youtube.com/watch?v=czmulJ9NBP0. and time is at 1.37.41
Your route is named /users not /user. So try navigating to /users in your browser instead and it should work.

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);
I have this ordinary expressjs app.js
/**
* 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();
// 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);
http.createServer(app).listen(app.get('port'), function(){
console.log('Express server listening on port ' + app.get('port'));
});
and i want to remove
app.get('/', routes.index);
app.get('/users', user.list);
and put them in a separate file.I am trying this
module.exports = function(/* any dependency? */){
app.get('/', routes.index);
app.get('/users', user.list);
}
and in the app.js file i have require('./routed.js');
but this do not work.How should i fix this?.
I took krasu's answer and modified a bit
routed.js
var routes = require('./routes');
var user = require('./routes/user');
module.exports = function(app){
app.get('/', routes.index);
app.get('/users', user.list);
}
in app.js
require('./routed.js')(app);
and this works.
Try this:
app.use(express.static(path.join(__dirname, 'public')));
require('./routed.js')(app);
And in ./routed.js
module.exports = function(app){
app.get('/', routes.index);
app.get('/users', user.list);
}
I'v got express app like this.
var express = require('express');
var http = require('http');
var path = require('path');
var app = express();
// all environments
app.set('port', process.env.PORT || 3000);
app.set('views', __dirname + '/views');
app.set('view engine', 'ejs');
app.use(express.favicon());
app.use(express.logger('dev'));
app.use(express.bodyParser());
app.use(express.methodOverride());
app.use(express.cookieParser());
app.use(express.static(path.join(__dirname, 'public')));
app.use(app.router);
app.get('*', function(res,req) {
req.render('index', {title: "Title"});
});
http.createServer(app).listen(app.get('port'), function () {
console.log('Express server listening on port ' + app.get('port'));
});
Because of using app.get('*') request to not existent static files responses with rendered index.ejs file instead of error 404.
Is there any way to fix it without additional conditions in routes?
Just add something like:
app.get(/\/(js|css|img)\/.*/, function (req, res) {
res.send(404);
});
before app.get('*'). Any request to /js that wasn't already matched by the static middleware references an file that does not exist.
Resolved problem by nginx proxying
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={...})
i have written a simple hello world program in express node.js and when i call it through Curl it's response is correct i.e it displays Hello world on the console but when i call the url from browser i get could not connect error.Here is my code:

app.use(express.errorHandler());
}
app.get('/', routes.index);
app.get('/users', user.list);
app.get('/partner', function(req, res){
res.send('Hello World');

http.createServer(app).listen(app.get('port'), function(){
console.log('Express server listening on port ' + app.get('port'));
});
You have either a DNS issue or a Firewall issue.
