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've been trying to do a route in Express. For example one /about route, but it doesn't work.
var express = require('express');
var app = express();
var router = express.Router();
var moment = require('moment');
var bodyParser = require('body-parser');
var multer = require('multer'); // v1.0.5
var upload = multer(); // for parsing multipart/form-data
app.use(bodyParser.json()); // for parsing application/json
app.use(bodyParser.urlencoded({ extended: true })); // for parsing application/x-www-form-urlencoded
app.get('/', function (req, res) {
//some action
});
app.get('/time', function (req, res) {
//...
});
app.get('/about', function (req, res) {
res.send('about');
});
Currently after calling url/about I'm getting Cannot GET /about as a return and after some research I've got no idea how to resolve this issue. They even describe it that way in the official express docs.
Thank you in advance.
You have something like this in your code? :
app.listen(SERVER_PORT, function () {
console.log("Server successfully started on port:" + SERVER_PORT); });
We should have something like this:
var express = require('express');
var routes = require('./routes');
var http = require('http');
var path = require('path');
const 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('/about', routes.about);
and also in the views folder: about.jade
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.
i'm trying to use Mongo-Express to lookup my mongoDB, I newbee, after i went under the user and pass i got error -> Cannot GET /
var express = require('express')
, routes = require('./routes')
, http = require('http');
var _ = require('underscore');
var async = require('async');
var utils = require('./utils');
var mongodb = require('mongodb');
var cons = require('consolidate');
var swig = require('swig');
var swigFilters = require('./filters');
var app = express();
var config = require('./config');
//Set up swig
app.engine('html', cons.swig);
Object.keys(swigFilters).forEach(function (name) {
swig.setFilter(name, swigFilters[name]);
});
//App configuration
app.configure(function(){
if(config.useBasicAuth){
app.use(express.basicAuth(config.basicAuth.username, config.basicAuth.password));
}
app.set('views', __dirname + '/views');
app.set('view engine', 'html');
app.set('view options', {layout: false});
app.use(express.favicon());
app.use(express.logger('dev'));
app.use(config.site.baseUrl,express.static(__dirname + '/public'));
app.use(express.bodyParser());
app.use(express.cookieParser(config.site.cookieSecret));
app.use(express.session({
secret: config.site.sessionSecret,
key: config.site.cookieKeyName
}));
app.use(express.methodOverride());
app.use(app.router);
});
First of all, try to learn from actual/updated tutorials. Actual express version is 4, and it removes:
app.use(app.router);
(therefore my deduction of outdated tutorial)
Second thing, i dont see in your code any routes. If you want to get responses from server, you need to write routes. For example:
app.get('/test', function(req, res) {
res.send('Hello from route');
});
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);
}
A razor view engine for nodejs.
https://github.com/nufyoot/kally-razor
I have tried something like this.. but no luck.
var razor = kallyrazor({
root: __dirname + '/views/',
layout: 'shared/layout.html'
});
app.engine('html', function (path, options, fn) {
fn(null, razor.render(path, options));
});
Worked for me. Did you include the view engine?
app.set('view engine', 'cshtml');
Note: I chose the use the cshtml extentionm just for vanity.. (And also in Sublime if that is your editor the razor syntax highlighter, https://github.com/joseph-turner/Razor)
Full code:
var express = require('express');
var routes = require('./routes');
var user = require('./routes/user');
var http = require('http');
var path = require('path');
var KallyRazor = require('kally-razor');
var app = express();
// all environments
app.set('port', process.env.PORT || 3000);
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'cshtml'); // NOTE THE VIEW ENGINE
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')));
// Setup KallyRazor
var razor = KallyRazor({
root: __dirname + '/views/',
layout: '/shared/layout.cshtml'
});
app.engine('cshtml', function (path, options, fn) {
fn(null, razor.render(path, options));
});
// 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'));
});
