I am not able to import the CSS for the nested routes
const express = require("express");
const cookieParser = require('cookie-parser');
const path = require('path')
const app = express();
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'ejs')
app.use(express.static('public'))
app.use('/images', express.static(__dirname + '/imgs'));
app.use("/css", express.static(__dirname + "/css"))
app.listen(3000);
app.use(express.json());
app.use(cookieParser());
const userRouter = require('./Routers/userRouter');
app.use("/users", userRouter);
const basicRouter = require("./Routers/basicRouter")
app.use("/", basicRouter);
userRouter.js
userRouter.route("/login")
.get(loginPage)
if i use this login page with out /users (means with localhost:3000/login)it is working fine but with /users/login it is giving me issue.
Any solution would be appreciated.
Thanks in advance.

I keep getting "app.engine('handlebars', handlebars()); type error 'handlebars' is not a function? Is there anything wrong in my code?
const express = require('express');
const nodemailer = require("nodemailer");
const paths = require('path');
const handlebars = require('express-handlebars')
const app = express();
require("dotenv").config();
//View engine setup
app.set("view engine", 'handlebars');
app.engine('handlebars', handlebars());
//Static Folder
app.use('/public', express.static(path.join(__dirname, 'public')))
//Body Parser MiddleWars;
app.use(express.urlencoded({extended: false}));
app.use(express.json())
const port = 3001;
app.listen(port, () => {
console.log(`Server is running on port: ${port}`);
});
According to the examples express-handlebars provided, you must import the engine function from the module:
(Using Imports)
import express from 'express';
import { engine } from 'express-handlebars';
const app = express();
app.engine('handlebars', engine());
app.set('view engine', 'handlebars');
app.set("views", "./views");
app.get('/', (req, res) => {
res.render('home');
});
app.listen(3000);
So, instead of calling handlebars directly, you should be calling handlebars.engine.
In total:
const express = require('express');
const nodemailer = require("nodemailer");
const paths = require('path');
const handlebars = require('express-handlebars')
const app = express();
require("dotenv").config();
//View engine setup
app.set("view engine", 'handlebars');
app.engine('handlebars', handlebars.engine());
//Static Folder
app.use('/public', express.static(path.join(__dirname, 'public')))
//Body Parser MiddleWars;
app.use(express.urlencoded({extended: false}));
app.use(express.json())
const port = 3001;
app.listen(port, () => {
console.log(`Server is running on port: ${port}`);
});
router.get('/dist/', function(req, res, next) {
res.render('index', { title: 'Express' });
});
my app.js routing code
app.set('dist', path.join(__dirname, 'dist'));
app.set('view engine', 'html');
app.engine('html', require('hbs').__express);
my folder structure
root/dist/index.html
I cannot open this page on my first page
how can I open this page? Where is my mistake?
thank you for your help
You can use the method set() to redefine express's default settings.
app.set('views', path.join(__dirname, '/dist'));
Working Example
const express = require('express')
const path = require('path')
const app = express()
const port = 3000;
var indexRouter = require('./routes/index');
// Set 'views' directory for any views
// being rendered res.render()
app.set('views', path.join(__dirname, '/dist'));
// Set view engine
app.engine('html', require('hbs').__express);
app.set('view engine', 'html');
app.use('/', indexRouter);
app.listen(port, () => console.log(`Example app listening at http://localhost:${port}`))
routes/index.js
var express = require('express');
var router = express.Router();
router.get('/dist/', function(req, res, next) {
res.render('index', { title: 'Inside Dist Folder Index' });
});
module.exports = router;
EJS Error: Failed to lookup view "admin_landing2" in views directory "/Users/aryanarora/Desktop/asn3/views".
while trying make a call to localhost/8080/yolo
I am getting the same error even if I switch to hbs. (i have installed both the packages)
var express = require("express");
var app = express();
var port = process.env.PORT || 8080;
var path = require('path');
var bodyParser = require('body-parser')
var MongoClient = require('mongodb').MongoClient;
var url = "mongodb://localhost:27017/";
var fs = require('fs');
// const hbs = require('hbs');
// hbs.registerPartials(__dirname + './views');
// app.set('view engine','hbs');
// Require static assets from public folder
app.use(express.static(path.join(__dirname, 'public')));
// Set 'views' directory for any views
// being rendered res.render()
app.set('views', path.join(__dirname, 'views'));
// Set view engine as EJS
app.engine('html', require('ejs').renderFile);
app.set('view engine', 'ejs');
var users = [];
//app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));
app.use('/', function(req,res,next){
console.log(req.method, 'request:', req.url);
next();
});
app.locals.yolo = require('./Data/courses.json');
//Request i am trying to get//
app.get('/yolo',function(req,res){
//res.sendFile(path.join(__dirname + '/admin_landing2.hbs'));
res.render('admin_landing2', {var1 : "pehla" , var2 : "dusra"});
});
app.get('/login', function(req,res){
res.sendFile(path.join(__dirname + '/admin_login.html'));
var filepath = './admin_login.html';
console.log(filepath);
});
The problem is that you're setting the views directory to the wrong location.
Do
app.set('views', __dirname)
instead of
app.set('views', path.join(__dirname, 'views'))
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.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');
});
var express = require('express')
var router = express.Router();
I am debugging my Node app and express is defined, but after stepping over the var router line, router is still undefined, how could this happen?
Well here is all the code if you must:
var express = require('express')
// , fancy_scripts = require('./fancy_scripts')
, routes = require('./routes')
, user = require('./routes/user')
, http = require('http')
, path = require('path');
var favicon = require('serve-favicon');
var logger = require('morgan');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');
// New Code
var mongo = require('mongodb');
var monk = require('monk');
var db = monk('localhost:27017/sparks');
var app = express();
// all environments
app.set('port', process.env.PORT || 3000);
app.set('views', __dirname + '/views');
app.set('view engine', 'jade');
app.engine('html', require('ejs').renderFile);
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')));
app.use(express.static(__dirname + '/fancy_scripts'));
app.use('/fancy_scripts', express.static(__dirname + '/fancy_scripts'));
app.use(function(req,res,next){
req.db = db;
next();
});
app.get('/', routes.index);
//var router = express.Router();
//
///* GET home page. */
//router.get('/', routes.index);
If were to guess the line app.use(app.router);
might be the culprit...?
