Issue with partials using EJS in express - node.js

Just to preface: I've recently been transitioning my web development skills from PHP + HTML/CSS to Nodejs, but have been having trouble with templating.
I'm using Express, and after some research tried to use Pug.js, but found that too complicated for what I'm trying to achieve at the moment, so I moved to ejs as it seemed to be more simple.
What I'm trying to get is to be able to reuse HTML that I have already written for multiple pages on the site - which from what I've found is called 'partials'?
Now to the code I've written so far:
server.js:
var express = require('express');
app = express();
publicFolder = __dirname + '/public';
app.set('view engine', 'ejs');
app.use(express.static(publicFolder, {
extensions: ['html']
}));
app.listen(80, () => {
console.log('Server is online on port 80')
});
index.html: (/public/index.html)
<html>
<body>
<% include ../views/header.ejs %>
</body>
</html>
header.ejs: (/views/header.ejs)
<h1>Test header</h1>
I understand I may be on the completely wrong track, but any help would be greatly appreciated.
Regards
EDIT: I've double checked to make sure it's not a path issue

It might be easier for you to store all your view files as ejs in the same folder and user the path module to set your static files.
server.js:
var express = require('express');
var path = require('path')
app = express();
app.use(express.static(path.join(__dirname, 'public')));
app.set('views', path.join(__dirname, 'views'))
app.set('view engine', 'ejs')
app.listen(80, () => {
console.log('Server is online on port 80')
});
index.ejs
<html>
<body>
<% include header %>
</body>
</html>
Just a consideration. Hope it helps!

rendering in nodejs using express to html

I'm trying to get values from nodejs into HTML. I've seen lot of answers, but none of them is working.
here what I've done so far:
index.html
<!DOCTYPE html>
<html>
<head>
<meta charset='utf-8'>
<meta http-equiv='X-UA-Compatible' content='IE=edge'>
<title>Page Title</title>
<meta name='viewport' content='width=device-width, initial-scale=1'>
<link rel='stylesheet' type='text/css' media='screen' href='main.css'>
</head>
<body>
<div>
<a id="test" name="test"> <%=name%></a>
</div>
</body>
</html>
app.js
const express =require('express')
const app = express();
var os = require( 'os' );
var path = require('path')
const PORT = process.env.PORT ||2000;
app.engine('html', require('ejs').renderFile);
app.get('/',(req,res)=>{
res.sendFile(path.join(__dirname+'/index.html'))
})
app.get('/test', (req, res)=> {
var name = 454;
res.render( "/index.html", {name:name});
});
app.listen(2001)
I don't get what I'm doing wrong. but it doesn't work as expected.
any idea how may I solve this ?
thanks in advance !
First, create a folder views and put your index.ejs right there (though, I am not sure, the extension have to be .ejs).
Then set the engine with:
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'ejs');
And change your routing to:
app.get('/', (req,res) => {
res.render('index', { name: 'Test' });
});
Edit: I have used the express application generator and also checked Using template engines with Express.
Edit: According to the extension .ejs:
One thing to note is that all files in which ejs syntax are used in
must be saved with a .ejs extension [...]
Taken from Using EJS as a Template Engine in your Express App, not from the official docs.

Cannot GET / Express ERROR

I am learning Mean.js stack, and try to build an app. I have installed Express, and it works. When I tried to configure my static file ( html, js, images, etc.), then things broke.
Here are my files:
server.js
var express = require('express');
var app = express();
app.use(express.static(__dirname + "public"));
app.listen(3000);
console.log('Server running on port 3000');
My html file is very simple :
<!DOCTYPE>
<html>
<head>
<title>Contact List App</title>
</head>
<body>
<h1>Contact List App</h1>
</body>
</html>
So when I start the server : node server.js, and then I type http://localhost:3000/ in the browser, I get the "Cannot Get" error.
Where is the problem?
__dirname doesn't have a trailing slash, so you need to provide one yourself when building the static root:
app.use(express.static(__dirname + "/public"));
^ this needs to be there
You need to make sure the route exists. Also, it is a better practice to use path for joining strings. Also, make sure the directory public exists and the file index.html is inside that folder.
var path = require('path');
var express = require('express');
var app = express();
app.use(express.static(path.join(__dirname, 'public')));
app.get('/', function(req, res){
res.render('index.html');
});
app.listen(3000);
console.log('Server running on port 3000');

nodejs send html file to client

I use this function to send html file to client, but in client I get nothing (blank page) without error. Something I wrong?, please help?
var express = require('express');
var fs = require('fs');
var app = express();
app.set('view engine', 'jade');
app.engine('jade', require('jade').__express);
app.get('/test', function(req, res) {
fs.readFile(__dirname + '/views/test.html', 'utf8', function(err, text){
res.send(text);
});
var port = process.env.PORT || 80;
var server = app.listen(port);
console.log('Express app started on port ' + port);
My test.html file
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<style something here </style>
<title>Test</title>
<script src="..."></script>
</head>
<body>
<div> Somthing here </div>
<script type="text/javascript">
//something here
</script>
</body></html>
Try your code like this:
var app = express();
app.get('/test', function(req, res) {
res.sendFile('views/test.html', {root: __dirname })
});
Use res.sendFile instead of reading the file manually so express can handle setting the content-type properly for you.
You don't need the app.engine line, as that is handled internally by express.
you can render the page in express more easily
var app = require('express')();
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'jade');
app.get('/signup',function(req,res){
res.sendFile(path.join(__dirname,'/signup.html'));
});
so if u request like http://127.0.0.1:8080/signup that it will render signup.html page under views folder.
After years, I want to add another approach by using a view engine in Express.js
var fs = require('fs');
app.get('/test', function(req, res, next) {
var html = fs.readFileSync('./html/test.html', 'utf8')
res.render('test', { html: html })
// or res.send(html)
})
Then, do that in your views/test if you choose res.render method at the above code (I'm writing in EJS format):
<%- locals.html %>
That's all.
In this way, you don't need to break your View Engine arrangements.
The "../" is considered malicious and will result in ForbiddenError: Forbidden at SendStream.error... exception.
The way to go is using a path module:
var path = require('path');
res.sendFile(path.resolve('views/auth/success.html'));
var app = express();
app.get('/test', function(req, res) {
res.sendFile(__dirname + "/view/test.html")
});
Here __dirname, gives you the current path where your files are saved. So in res.sendFile(), we first tell our current location by __dirname + (then we locate the specific file which should we shown on the home page i. e ) "vies/test.html".
Follow this simple process and send html file ->
res.sendfile("views/home.html"); // don't use capitla latter F with sendFile you must be use small letter f
example : sendfile();

angular js is not rendering in jade (with node.js)

I facing a problem that my Angularjs is not rendering or load in my Jade layout. Somehow the stylus is working perfectly with. I counldn't find out the reason why. I'm still the beginner in learing jade, stylus and angularjs

throw err;
});
thank you in advanced for everyone who helps
I suspect the issue you are having is that the path to your views that you have specified is wrong and you are serving them up statically.
For example, if you have your views in a sub-directory of the base directory, and you have set the base directory to be served up as static content, it will serve up the jade as static content.
What you should do is put your views in a different folder to the static content so that is a sibling not a child and this should work. If you want to post your directory structure I can have a look.

Cannot find view in node/express

As my username implies, I'm new to node.js. I'm trying to learn it. As part of this process, I'm working to setup a basic web site. This web site will show a couple of basic web pages and expose a single REST endpoint. The structure of my project is:
config.js
home.html
start.js
routes.js
server.js
resources
css
style.css
images
up.png
down.png
javascript
home.html.js
start.js has my main server code. That file gets executed via command line using 'node start.js'. Once started, my server begins listening on port 3000. The code in start.js looks like this:
var express = require('express');
var app = express();
var UserProfileHandler = require('./app/handlers/UserProfileHandler');
app.configure(function () {
app.engine('html', require('ejs').renderFile);
app.set('views', __dirname + '/');
app.use(express.logger({ stream: expressLogFile }));
app.use(express.bodyParser());
app.use(express.methodOverride());
app.use(app.router);
app.use(express.static(__dirname + '/public'));
});
var routes = {
userProfiles: new UserProfileHandler()
};
function start() {
routeConfig.setup(app, routes);
var port = process.env.PORT || 3000;
app.listen(port);
console.log("SUCCESS: Server listening on port %d in %s mode", port, app.settings.env);
}
exports.start = start;
exports.app = app;
My routes.js file has the following:
function setup(app, routes) {
viewSetup(app);
apiSetup(app, routes);
}
function viewSetup(app) {
app.get('/', function (req, res) {
res.render("/home.html");
});
app.get('/home.html', function (req, res) {
res.render("/home.html");
});
}
function apiSetup(app, routes) {
app.get('/api/userProfiles/:username', routes.userProfiles.getUserProfiles);
}
I am trying to load home.html in a browser window. I attempt this by visiting http://localhost:3000 and http://localhost:3000/ and http://localhost:3000/home.html. Unfortunately, none of these work. In fact, I receive an error that says:
Express 500 Error: Failed to lookup view "/home.html"
I know that I'm close. If I visit http://localhost:3000/api/userProfiles/me I receive a JSON response back like I'm expecting. For some reason, i can't seem to return HTML though. My home.html file looks like the following.
<html>
<head>
<script type='text/javascript' src='/resources/javascript/home.html.js'></script>
</head>
<body>
We're up and running! <img src='/resources/images/up.png' />
</body>
</html>
Its a pretty basic HTML file. Even if the HTML comes back though, I'm concerned the JavaScript file and Image it references won't be accessible. I'm concerned of this because I'm not really sure how paths and such work in Node.
How do I get home.html to work in my Node setup?
Thank you!
as your view file is in same folder as your main file, below changes should make it work
1.change the view folder configuration line
from
app.set('views', __dirname + '/');//wont work
to
app.set('views', __dirname);//will work
2.change view render lines
from
res.render("/home.html");//wont work
to
res.render("home.html");//will work
with both the changes, the view should be working fine
update to below comments.
the issue you mentioned regarding the images,css and js is due to the static folder configuration which should be changed from
app.use(express.static(__dirname + '/public'));
to
app.use(express.static(__dirname + '/resources'));
as your static folder is named resources.
but make sure in your view you are refering the css/js/image files like
eg:
/css/style.css
/images/up.png
/images/down.png
/javascript/home.html.js
from your view file
Also if the above dint work, check if you have given the path correctly and also you can try by taking the
app.use(express.static(__dirname + '/resources'));
before the
app.use(express.methodOverride());
app.use(app.router);
lines like
app.configure(function () {
app.engine('html', require('ejs').renderFile);
app.set('views', __dirname + '/');
app.use(express.static(__dirname + '/public'));
//try changing the position of above line in app.configure and resatrt node app
app.use(express.logger({ stream: expressLogFile }));
app.use(express.bodyParser());
app.use(express.methodOverride());
app.use(app.router);
});
had similar problem in my case is
app.set('./views');
look for the dot, dont know why but the dot will mess it up.
I had it like this
app.set('/views') and no matter what i did couldt find the folder until added the dot.
