Problem in rendering ejs template with Express

I am using Node.js together with Express and EJS.
Below is my code:
var express = require('express');
var path = require('path');
var bodyParser = require('body-parser');
var app = express();
var urlencodedParser = bodyParser.urlencoded({ extended: false });
var publicPath = path.resolve(__dirname, 'public');
app.use(express.static(publicPath));
//app.set('views', __dirname + '/views');
app.set('view engine', 'ejs');
app.get('/form_get.html', (req, res) => {
res.sendFile(__dirname + "/" + "form_get.html")
})
app.get('/process_get', (req, res) => {
console.log(req.query.first_name);
res.render(path.join(__dirname+'/views/thankyou.ejs'), { name: req.query.first_name});
})
var server = app.listen(3000, () => {
var host = server.address().address;
var port = server.address().port;
console.log(`Example app listening at ${host}:${port}`);
})
My folder structure is below:
mysql (folder)
node_modules (folder)
app4.js (file)
package.json (file)
public (folder, it contains form_get.html)
views (folder, it contains thankyou.ejs)
The problem is the failing to look up thankyou.ejs into the views folder.
I get the following error message:
Error: Failed to lookup view "thankyou.ejs" in views directory
".../mysql/views"
What can be the problem?

When You use app.set('view engine', 'ejs'); It is important to note that res.render() will look in a views folder for the view.
In this case
I mirrored Your project and it works fine with couple tiny changes...
Project Folder and file structure.
app.js
var express = require("express");
var path = require("path");
var bodyParser = require("body-parser");
var app = express();
var urlencodedParser = bodyParser.urlencoded({ extended: false });
var publicPath = path.resolve(__dirname, "public");
app.use(express.static(publicPath));
app.set("view engine", "ejs");
app.get("/form_get", (req, res) => {
res.sendFile(__dirname + "/" + "form_get.html");
});
app.get("/process_get", (req, res) => {
res.render("thankyou");
});
var server = app.listen(3000, () => {
var host = server.address().address;
var port = server.address().port;
console.log(`Example app listening at ${host}:http://localhost:${port}`);
});
Output:
http://localhost:3000/process_get (thankyou.ejs) file.
Output:
http://localhost:3000/form_get (form_get.html) file

Can't seem to render a page through express

I'm trying to render an html page with express. Here's what I have so far:
var express = require('express');
var app = express();
app.use(express.static(__dirname + '/public'));
app.set('view engine', 'ejs');
app.listen(3000, function() {
console.log('listening on PORT 3000');
})
app.get('/', function(req, res){
res.send('Home page!')
})
app.get('/events', function(req, res){
res.render('eventForm')
})
my file tree so far:
-Project
-node_modules
-public
index.html
-views
eventForm.html
I tried putting the eventForm.html in public as well but for some reason my server can't "find" it. I get the following error:
Error: Failed to lookup view "eventForm" in views directory "/Users/username/LearnProgramming/api_playground/stubhub/views"

set your views before setting view engine
app.set('views', path.join(__dirname, 'views'));

var express = require('express');
var app = express();
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'ejs');
app.listen(3000, function() {
console.log('listening on PORT 3000');
})
app.get('/', function(req, res){
res.send('Home page!')
})
app.get('/events', function(req, res){
res.render('eventForm')
})
app.use(express.static(__dirname + '/public'));

How about eventForm with .html?

Unable to render index.html file from my view folder in angular2

I'm creating a MEAN Stack application where angular has setup in /client folder. I want that when I run npm start command in /client folder it should render index.html file from /views folder, what I'm doing wrong getting this error
Cannot GET /
Folder structure is as follows.
meanApp
----- client (angluar2 setup here but doesn't have an index.html file)
---------- app
----- views
----------index.html
----- routes
----- server.js
Codes in server.js
var express = require("express");
var path = require("path");
var bodyParser = require("body-parser");
var index = require('./routes/index');
var tasks = require("./routes/tasks");
var app = express();
//View engines
app.set("views", path.join(__dirname,'views'));
app.set("view engine", 'ejs');
app.engine("html", require("ejs").renderFile);
//Set static folder
app.use(express.static(path.join(__dirname,'client')));
// Body parser
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({extended:false}));
app.use('/', index);
app.use('/index', index);
app.use('/api', tasks);
//listen
app.listen(3000, function(){
console.log("Server listing # 3000");
});

Here you need to define route for express server like :
app.set('appPath', 'client'); //this is a folder where your index.html is
app.route('/*')
.get(function(req, res) {
res.sendfile(app.get('appPath') + '/index.html');
});
This will cause every call in broweser to render index file.

const http = require('http');
fs = require('fs');
var express = require('express');
var bodyParser = require('body-parser');
var expressValidator = require('express-validator');
var app = express();
app.set('appPath', 'views');
app.use(express.static(__dirname + '/views'));
app.use(bodyParser.urlencoded({ extended: true }));
app.use(bodyParser.json());
app.use(expressValidator());
app.use('/*', function(req, res, next) {
res.sendfile(app.get('appPath') + '/index.html');
});
http.createServer(app).listen(3001, function() {
console.log(`Express server listening on port 3001`);
});
exports = module.exports = app;

Node + Express JS API is not working

I'm a beginner in node.js but I try a little harder to setup a structure in node + express js.I start doing with the front-end and separate API structure.I put a single app.js for both API and front-end.But my API is not working. it gives error Cannot GET /api/users when i call http://localhost:3000/api/users. please help
api
-controllers
-helpers
-middlewares
-models
-routes.js
app.js
controllers
helpers
middlewares
models
node_modules
package.json
public
views
app.js
var express = require('express')
, app = express()
, bodyParser = require('body-parser')
, port = process.env.PORT || 3000
var path = require('path');
app.set('views', path.join(__dirname, 'views/'));
app.set('view engine', 'ejs')
app.use(express.static(__dirname + '/public'))
app.use(bodyParser.json())
app.use(bodyParser.urlencoded({extended: true}))
app.use(require('./controllers'))
var routes = require('./api/routes');
app.use('/api', routes);
app.listen(port, function() {
console.log('Listening on port ' + port)
})
routes.js
var express = require('express')
, router = express.Router()
var usersController = require('./controllers/users');
module.exports = function (app) {
app.get('/users', usersController.getUser);
};
module.exports = router;
users.js(controller)
module.exports = {
getUser: function (req, res) {
console.log("sdfdsfdsfsd");
res.setHeader('Content-Type', 'application/json');
res.send(JSON.stringify({"msg": "welcome user"}));
}
}

In your routes.js file you are exporting two things. Try to only export the router
var express = require('express')
, router = express.Router()
var usersController = require('./controllers/users');
router.get('/users', usersController.getUser);
module.exports = router;

Using Socket.io with Node.js, Express and Jade

I have some trouble to use Socket.io even just to test if a client is connected. I've tried many things and I think that my mistake is, maybe, when I do the app.get function. I have also tried to do this in an route js file but it wasn't conclusive neither. So here are my different codes :
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 mongo = require('mongodb');
var monk = require('monk');
var db = monk('mongodb://xxxxx:xxxxx#ds051067.mongolab.com:51067/jdo');
var app = express(),
server = http.createServer(app) ,
io = require('socket.io').listen(server);
// 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(express.cookieParser('This is secret'));
app.use(express.session());
app.use(app.router);
app.use(express.static(path.join(__dirname, 'public')));
// development only
if ('development' == app.get('env')) {
app.use(express.errorHandler());
}
io.sockets.on('connection', function (socket) {
console.log('Un client est connecté !');
});
// app.get('/', routes.index);
app.get('/users', user.list);
app.get('/deplacement',routes.deplacement);
app.get('/monCompte', routes.compte);
app.get('/connexion', routes.connexion);
app.get('/', function(req, res) {
res.render('index.jade');
});
server.listen(app.get('port'), function(){
console.log('Express server listening on port ' + app.get('port'));
});
Index.jade
extends layout
block content
script(src="/socket.io/socket.io.js").
var socket = io.connect('http://localhost:3000');
});
PS : Sorry if my english is bad ^^

You can't use inline javascript in the same script tag as an included script.
extends layout
block content
script(src="/socket.io/socket.io.js")
script.
var socket = io.connect('http://localhost:3000');
