If you want to use ejs templating as your view engine then you can use below code to set the view engine for your node application
const ejs=require("ejs");
app.set('view engine','ejs');

Using this express-validator version I got this error when submit, using last express-validator version I get same error in console.
Why I'm getting this error??
The reason is the way you are requiring it.
const { body, validationResult } = require('express-validator');
In your code you can make these changes and try:
const { validationResult } = require('express-validator');//#5.3.1
.
.
.
app.use(validationResult());
Note: check this link for more information.
I used express-generator and the following are app.js:
var createError = require('http-errors');
var express = require('express');
var path = require('path');
var cookieParser = require('cookie-parser');
var logger = require('morgan');
var cors = require('cors');
var app = express();
app.use(cors());
// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'jade');
app.use(logger('dev'));
app.use(express.json());
app.use(express.urlencoded({ extended: false }));
app.use(cookieParser());
app.use(express.static(path.join(__dirname, 'public')));
var indexRouter = require('./routes/index');
var usersRouter = require('./routes/users');
app.use('/', indexRouter);
app.use('/users', usersRouter);
// catch 404 and forward to error handler
app.use(function (req, res, next) {
next(createError(404));
});
// error handler
app.use(function (err, req, res, next) {
// set locals, only providing error in development
res.locals.message = err.message;
res.locals.error = req.app.get('env') === 'development' ? err : {};
// render the error page
res.status(err.status || 500);
res.render('error');
});
module.exports = app;
And when access to http://localhost:5000/api/ got Error:

Following is routes/index:
var express = require('express');
var router = express.Router();
/* GET home page. */
router.get('/', function(req, res, next) {
res.render('index', { title: 'API' });
});
module.exports = router;
Thank you very much for your helps !
The issue is that you define a GET / route in your routes/index.js file and then register it as app.use('/', indexRouter) in your app.js.
So you either change your routes/index.js file to it looks like this:
var express = require('express');
var router = express.Router();
// Note the /api
router.get('/api', function(req, res, next) {
res.render('index', { title: 'API' });
});
module.exports = router;
Or you keep routes/index as it is but your change the way your register it in your main.js to this:
// ...
// Note the /api
app.use('/api', indexRouter);
app.use('/users', usersRouter);
// ...

var router = express.Router();
var callFunction = require('../app');
router.get('/', function(req, res, next) {

callFunction.getDataFromDb(res);
});
module.exports = router;
I just want to call a function from another file.
You're using module.export. The Correct property name is module.exports, which you are also using.
One way to solve this is:
app.getDataFromDb = getDataFromDb;
module.exports = app;
for my app i use node.js as backend and Express as framework. I use Netbeans as IDE and i get the following output.

I have the following data setup:
- node-modules
- public
- fonts
- images
- javascripts
- stylesheets
stylesheets.less
stylesheet.css
- routes
index.js
news.js
users.js
- views
index.jade
error.jade
news.jade
layout.jade
Gruntfile.js
app.js
gulpfile.js
package.json
the app.js looks like this
var news = require('./routes/news');
var index = require('./routes/index');
var users = require('./routes/users');
var app = express();
// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'jade');
...
app.use('/', index);
app.use('/index', index);
app.use('/news', news);
app.use('/users', users);
and this is my index.jade
h3
a(href="news") link
and this my news.jade
h3 test
.
The routing is realised over route files.
index.js
var express = require('express');
var router = express.Router();
/* GET home page. */
router.get('/', function(req, res, next) {
res.render('index');
});
router.get('/index', function(req, res, next) {
res.render('index');
});
module.exports = router;
the news.js router file is
var express = require('express');
var router = express.Router();
/* GET home page. */
router.get('news', function(req, res, next) {
res.render('news');
});
module.exports = router;
The following circumstances are
the routing on the links "/" and "index" works as wanted.
the routing on "/news" or "news" (tested in the rounting, app.js and view file) not. I have no clue why the routing isn't working. I hope i haven't forgotten sth.
Thx,
Inge
Your code works for me.

The news route file is missing. There you have to render your jade.
var news = require('./routes/news');
Trying to add a new route to this Express app using the Express app generator. this is the app.js file:
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 parse = require('./routes/parse');
var app = express();
// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'jade');
// uncomment after placing your favicon in /public
//app.use(favicon(path.join(__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('/parse', parse);
// catch 404 and forward to error handler
app.use(function(req, res, next) {
var err = new Error('Not Found - from app.js');
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;
The lines i added are:
var parse = require('./routes/parse');
app.use('/parse', parse);
Then in the /routes directory i added parse.js that contains:
var express = require('express');
var router = express.Router();
router.get('/parse', function(req, res, next) {
res.send('return from parse.js');
});
module.exports = router;
I can hit the / and the /users resource using a browser and i get the expected result. But when i try to hit /parse i get this 404:
Not Found - from app.js
404

Try /parse/parse in the URL
If you would like to use /parse, please use / instead of /parse in /routes/parse.js
Please refer /routes/index.js & /routes/users.js.
TL;DR;
app.js
var parse = require('./routes/parse');
app.use('/parse', parse);
routes/parse.js
var express = require('express');
var router = express.Router();
// the URL pattern will be used in conjunction with how its is being used
// in this case it would be '/parse' (from app.js) + '/parse' (as used in the next line)
// resulting in '/parse/parse'
router.get('/parse', function(req, res, next) {
res.send('return from parse.js');
});
module.exports = router;
