my foldr structute is
example(parent folder)
subfolders
app/views/layout.html(code is given above)
public/scripts/js files
public/styles/css files
app.js(code is given above)
all the above subfolder(app,public,app.js) at the same level
so please suggest me some thing
It should work if you remove the 'public' from your URLs, like:
<link rel="stylesheet" href="/styles/bootstrap.css">
<link rel="stylesheet" href="/styles/example-basic.css">
You setup the static directory to be /public so its going to look in there for static resources. You did that here:
app.use(express.static(__dirname+'/public'));
When you add public to those URLs, it will be looking in /public for a folder called public, which it won't find. It will however find a folder called styles.

I have an issue rendering data in an EJS-template. The Object with data is present on the page but when I try to show a specific part of the data it won't render (like recept.title).
Router
router.get("/:slug", function(req, res) {
Recept.find({ slug: req.params.slug})
.exec(function(err, foundRecept) {
if(err || !foundRecept) {
req.flash("error", "Recept niet gevonden");
res.redirect("back");
} else {
res.render("recepten/recept", { recept: foundRecept });
}
});
});
When I render the whole object it will render (as shown below).
HTML File
<div class="row justify-content-center">
<div class="col-md-9">
<div class="card-img-top">
//this doesn't render
<img
class="card-img-top"
src="<%= recept.image %>"
alt="<%= recept.title %>"
/>
</div>
<div class="card-title">
<h1 class="h3"><%= recept.title %></h1>
<p>
//this will render the JSON object
<%= recept %>
</p>
</div>
</div>
</div>
Many thanks in advance.
Regards Jason
Sample Code:
index.js
const express = require("express")
const path=require("path");
const app = express()
app.set('views', path.join(__dirname, '/public'));
app.engine('html', require('ejs').renderFile);
app.set('view engine', 'html');
// being rendered res.render()
const port = 3000
app.get('/', (req, res) => {
var foundRecept=[{"title":"mango"},{"title":"apple"}]
res.render(__dirname + "/public/" + "index.html", { recept: foundRecept });
})
app.listen(port, () => {

I'm currently using NodeJs/Express and EJS for my web application. My goal was to build a simple page, with an input field, for testing XSS attacks. I'm not too experienced with building server-side applications. I was wondering how to send/retrieve the inputs from my text field.
And how do I add a CSS file?
// app.js
var express = require("express");
var path = require("path");
var routes = require("./routes"); // defines routes
var app = express();
app.set("port", process.env.PORT || 3000); // defines port
app.set("views", path.join(__dirname, "views"));
app.set("view engine", "ejs");
app.use(express.urlencoded({ extended: false}));
app.use(routes);
app.listen(app.get("port"), function() {
console.log("Server started on port: " + app.get("port"));
});
// routes.js
var express = require("express");
var router = express.Router();
router.get('/', function(req, res, next) {
console.log("Hello I'm on the start page here.");
res.render('index', {page:'Home', menuId:'home'});
});
router.get('/about', function(req, res, next) {
res.render('about', {page:'About Us', menuId:'about'});
});
module.exports = router; // export variables
// header.js

So, you are sending data to the server so you need to have a POST HTTP request.
app.post('/add', (req, res) => {
let inputText = [];
inputText.push(req.body.userInput)
res.render('index', {
inputText,
});
});
Now to get the value from the user input you need to write the below code in your index.ejs file
<% if (locals.inputText){ %>
<% inputText.forEach(function (text) { %>
<h5><%= text %></h5>
<% }) %>
<% } %>
im building a project in node/express/ejs and struggling to link the css to the ejs files and getting the css to show up in the browser. Ive created a public folder with a css folder inside that and the the main.css file inside.

The first step is to verify that your CSS is being served on the url you expect.
Go to your browser and check that your css is being served properly on url http://localhost:8080/css/main.css
If it is then this means you have a bad path to the css in your HTML. If its not being served properly then its either not configured properly or its at a different url.
My suspicion is that your url css/main.css(which is a url relative to the current page url) should be /css/main.css instead(which is relative to the root of your application).
I'm trying to build an app that lets me enter in information about an event and then have that pinned on a map. I'm stuck at the beginning though on actually saving the information. When I use Inspect in Chrome, it tells me it posted, but the data is blank. I'm pretty new to this kind of stuff and not sure where I'm going wrong.
The first file is the app.js where I set up the database, a simple partial schema, etc.
The second file is my dashboard.html that displays the map and the form. I was trying the onsubmit/javascript stuff which displays the data without refreshing the page, but ideally I want to be able to refresh the page and have the data still be posted somewhere.
Any help would be greatly appreciated! Thanks! :)

You should use body-parser to change your data post from client to json
var bodyParser = require('body-parser')
app.use(bodyParser.json())
You can get json data via req.body

I don't want change html and js too much and don't use express package.
Before answering your question...
Your question aims at serving static web content.
You should install 'express' (a node module based on famous 'connect', which can be used for this as well but lacks other features) and configure it to serve your file from a static directory:
var express = require('express');
var app = express.createServer();
/* configure your static directory */
app.configure(function(){
app.use(express.static(__dirname + '/static'));
});
/* on request, send index.html */
app.get('/', function(req, res){
res.sendfile(__dirname + '/index.html');
});
app.listen(3000);
Now that you have express installed, take a look at Jade.
You can then process received requests and dynamically serve content. That's state of the art - serving pre-coded html is 90's-style.
