Hi I am currently learning NodeJS and the Express framework, but I am having issue with when I try to submit the form it suppose to go the '/users/register' URL but it seems that my app.js is not finding the register.jade file although I have a register.jade under the view folder. Here is some of my codes:
register.jade:
extends layout
block content
h1 Register
p Please register using the form below
ul.errors
if errors
each error, i in errors
li.alert.alert-danger #{error.msg}
form(method='post', action='/users/register', enctype='multipart/form-data') ...
user.js:
router.post('/users/register', function(req, res, next) { ... });
app.js:
var express = require('express');
var path = require('path');
var favicon = require('serve-favicon');
var logger = require('morgan');
var expressValidator = require('express-validator');
var cookieParser = require('cookie-parser');
var session = require('express-session');
var passport = require('passport');
var local = require('passport-local').Strategy;
var bodyParser = require('body-parser');
var multer = require('multer');
var flash = require('connect-flash');
var mongo = require('mongodb');
var mongoose = require('mongoose');
var db = mongoose.connection;
var index = require('./routes/index');
var users = require('./routes/users');
var app = express();
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'jade');
...
app.use('/', index);
app.use('/users', users);
app.use(function(req, res, next) {
var err = new Error('Not Found');
err.status = 404;
next(err);
});
Error on my Git Bash:
Error from the browser:
Here is my folder structure:
I am not sure why it errors out 404, thank you in advance!
As per the path mouting from your code, the url path in browser should be
localhost:3000/users/users/register
Either you can make change in
router.post('/users/register', function(req, res, next) { ... });
to
router.post('/register', function(req, res, next) { ... });
OR only make change in
app.use('/users', users);
to
app.use(users);
where your url path will be localhost:3000/users/register
The routes in your users router are relative to the mounted path, you should instead try:
router.post('/register', function(req, res, next) { ... });

I am tring to give 2 roots one for admin and other for user.
To access the admin pannel http://localhost:3000/admin
To access to user page http://localhost:3000.
But the problem is when an option is selected from the menu of admin pannel it will not take to that page , and shows a 404 error.[if i click option which have an href add-faq it must show like http://localhost:3000/admin/add-faq. but it is showing http://localhost:3000/add-faq and giving 404 error]
But the user page had no problems.
I am using node js,Express,Hbs.
All files are named properly and no files missing..
If the http://localhost:3000/admin/add-faq is manually given the stylesheets are not loading (404)

**My admin.js:**
var express = require('express');
var router = express.Router();
/* GET users listing. */
router.get('/', function(req, res, next) {
res.render('adminintro',{admin:true})
});
router.get('/add-prices', (req,res)=>{
res.render('faqadmin',{admin:true})
});
router.get('/add-faq',(req,res)=>{
res.render('faqadmin',{admin:true})
})
module.exports = router;
**my user.js:**
var express = require('express');
var router = express.Router();
/* GET home page. */
router.get('/', function(req, res, next) {
res.render('index',{admin:false,indexpage:true});
});
router.get('/faq',(req,res)=>{
res.render('faq',{indexpage:true})
});
router.get('/web-design-pricing',(req,res)=>{
res.render('price',{indexpage:true})
});
router.get('/e-commerce-pricing',(req,res)=>{
res.render('price',{indexpage:true})
});
router.get('/seo-pricing',(req,res)=>{
res.render('price',{indexpage:true})
});
module.exports = router;
Try adding the complete end point like below in /views/partials/admin-header.hbs file like below,
<li>FAQ</li>
Your user routes are with the endpoint '/' in server.js.So its working,where as admin need to be linked like /admin/add-faq
I am building a day planner, and while I was setting the routes I noticed I am receiving a 404 for every routes other than the main Home page route ie, index or "/".

And here is the Controller for the calendar.js route.

res.send('NOT IMPLEMENTED: Schedule update POST');
};
Okay I found the bug it was me using index url that is / which I redirected to /calendar. And I have been using the rest of the url routes without calling the redirected one ie, /calendar.
I tried calling the routes with /calendar/calendar and it works!
I don't yet know clearly how to explain this. I hope fellow stackoverflow'ers could explain why this is happening.
Here's me trying a noob explanation!
Redirecting index route / to another url route, changes the main url route of the website(address). So all the sub routes which is everything other than the index route should explicitly call the redirected route (new address). Because every-time we call the old address the redirection changes it to the new one. Making the old address a dead one.
(Humour : I would like to point out an example considering numbers. It's like whole numbers and natural numbers. Redirection is when the whole number changes to natural number.)
I am getting an error "indexRouter is not defined while I am trying to execute the following code. I tried removing the line but again there are other errors. Can anyone tell me why we are using this common variable router for both index.js and user.js?
This is my app.js

var favicon = require('serve-favicon');

// render the error page
res.status(err.status || 500);
res.render('error');
});
module.exports = app;
This is my index.js
var express = require('express');
var router = express.Router();
/* GET home page. */
router.get('/', function(req, res, next) {
res.render('index', { title: 'Express' });
});
module.exports = router;
This is my users.js
var express = require('express');
var router = express.Router();
/* GET users listing. */
router.get('/', function(req, res, next) {
res.send('respond with a resource');
});
module.exports = router;
You are using wrong variable.
var index = require('./routes/index');
var users = require('./routes/users');
app.use('/index',indexRouter); // it would be index
app.use('/users',usersRouter); // it would be users
Change from indexRouter to index and userRouter to users.
I'm learning about REST with node.
I'm trying to use post to add an element to my db.
My code:
var express = require('express');
var router = express.Router();
var mongoose = require('mongoose');
var AdModule = require('../models/ad');
router.route('/')
.get((req, res) => {
AdModule.find((err, col) => {
if (err)
res.send(err);
res.json(col);
})
})
.post((req, res) => {
var ad = new AdModule();
ad.title = req.body.title;
ad.desc = req.body.desc;
ad.price = req.body.price;
ad.save(err => {
if (err)
res.send('err' + err);
res.json({msg: 'Created'});
})
res.json(req);
});
module.exports = router;
When using post I get req.body is undefined.
My server.js code:
'use strict';

So I am using body parser.
This is how I'm posting with postman:
What can be the reason for this madness?
I'm guessing it's something with server.js but have no idea what.
I was following this tutorial.
https://scotch.io/tutorials/build-a-restful-api-using-node-and-express-4#creating-routes-for-a-single-item
Express middlewares executed by order that they are defined, in your case bodyParser defined after ads middleware, just move asd to the bottom
Put your parsers above your routes -- as it happens now, requests are hitting the routes before they have a chance to go through the parsers.
I'm fairly new to express js and I want to know how to use router. I created a file named categories.js inside routes directory with this code.
categories.js code:
var express = require('express');
var router = express.Router();
/* GET users listing. */
router.get('/categories', function(req, res) {
res.send('this is the category');
});
module.exports = router;
inside the app.js i have this code:
var express = require('express');
var path = require('path');
var favicon = require('serve-favicon');
var logger = require('morgan');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');
var routes = require('./routes/index');
var users = require('./routes/users');
var categories = require('./routes/categories');
var app = express();
var mongoose = require('mongoose');
mongoose.connect('mongodb://localhost/test');
// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'hjs');
// 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')));
app.use('/', routes);
app.use('/users', users);
app.use('/categories', categories);
// catch 404 and forward to error handler
app.use(function(req, res, next) {
var err = new Error('Not Found');
err.status = 404;
next(err);
});
// error handlers
// development error handler
// will print stacktrace
if (app.get('env') === 'development') {
app.use(function(err, req, res, next) {
res.status(err.status || 500);
res.render('error', {
message: err.message,
error: err
});
});
}
// production error handler
// no stacktraces leaked to user
app.use(function(err, req, res, next) {
res.status(err.status || 500);
res.render('error', {
message: err.message,
error: {}
});
});
module.exports = app;
I have tried understand what is wrong but i can't see to figure out. thanks in advance.
This is the error im getting
Not Found
404
I will like to add inside the routes directory i have a index.js file and this one works.
var express = require('express');
var router = express.Router();
/* GET home page. */
router.get('/', function(req, res, next) {
res.render('index', { title: 'Express' });
});
module.exports = router;
I think my application is not reading the categories.js file, because when I put the category.js code inside index.js it works. but it doesn't work if i put it in a separate file in my case category.js.
I think you've got your categories route hooked up wrong, your categories are mapped to /categories/categories in your code. To fix it, try this in your app.js:
app.use('/', categories);
If you don't want to prefix, you can also simply do this:
app.use(categories);
