Hi I am studying node js, meanwhile I am facing this issue.
app.use(express.static("public"));
app.use(bodyParser.urlencoded({ extended: true }));
app.use(bodyParser.json());
/*This route is working fine */
app.get("/:username", function (req, res) {
res.sendFile(__dirname + "/public/ui/" + "user.html");
});
/*This route is not working */
app.get("/:username/:id", function (req, res) {
res.sendFile(__dirname + "/public/ui/" + "user.html");
});
My folder Structure is
-server
-public
-ui
-ext (external files folder)
- images(all images folder)
-js (My js files folder)
-style (my css folder)
-user.html
-index.js
-user.js
When I am trying to load url http://localhost:8888/stranger/19, my page is loading but none of the files specified in user.html is not loading.
It seems like url of my css file is http://localhost:8888/stranger/ui/style/main.css instead of http://localhost:8888/ui/style/main.css.
This is happening for all files loading via ui. ("http://localhost:8888/stranger" this is coming instead of "http://localhost:8888"). How can I fix this issue

Add a route to static file to public directory
app.use(express.static('public'))
Here is the documentation on using the public folder
Then in your html take the path as,
<link rel="stylesheet" type="text/css" href="/ui/style/main.css">
Here are the working codes:
your app.js or server.js where the express is defined
var express = require('express');
var app = express();
app.use(express.static('public'))
app.get("/:username", function (req, res) {
res.sendFile(__dirname + "/public/ui/" + "user.html");
});
app.get("/:username/:id", function (req, res) {
res.sendFile(__dirname + "/public/ui/" + "user.html");
});
var server = app.listen(8081, function () {
var host = server.address().address
var port = server.address().port
})
Your user.html in public/ui direcrtory.
<html>
<head>
<link rel="stylesheet" type="text/css" href="/ui/style/main.css">
</head>
<body>
Page will be in green color due to css
</body>
</html>
Your css in public/ui/style directory.
body{
background: green;
}
Follow these steps and it will work.
The problem is with href attribute.
Your current href attribute in link tag is:
<link rel="stylesheet" href="ui/ext/bootstrap-3.3.4/css/bootstrap.min.css" >
Which means to use current url as base url. Change it to following:
<link rel="stylesheet" href="/ui/ext/bootstrap-3.3.4/css/bootstrap.min.css" >
Simply add / at the start and it should fix the problem.

I want to use middleware func to serve static file,but the problem is that my css file is not linking with html file using node and express
error is:
Refused to apply style from 'http://localhost:4000/static/css/style.css' because its MIME type ('text/html') is not a supported stylesheet MIME type, and strict MIME checking is enabled.
app.js:
const express=require('express');
const path=require('path');
const app=express();
app.use('/public',express.static(path.join(__dirname,'static')));
app.get('/',(req,res)=>{
res.sendFile(path.join(__dirname,'static','index.html'));
});
app.listen(3000);

folder structure is:

I tried a lot , but i am not able to find the error,
please help!!
Thanks!!
We will have to do something like that:
app.js
const express=require('express');
const path=require('path');
const app=express();
app.use('/public', express.static(path.join(__dirname,'./static')));
app.get('/',(req,res)=>{
res.sendFile(path.join(__dirname,'static','index.html'));
});
app.listen(3000, () => {
console.log("Starting at", 3000);
});
index.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Document</title>
<script src="/public/js/main.js"></script>
<link rel="stylesheet" href="/public/css/style.css">
</head>
<body>
<div class="asd">
Hi xyz here..
</div>
<script src="/public/js/script.js"></script>
</body>
</html>
Here is the screenshot:
A basic thumbs rule we can think of:
app.use('<something_here>', express.static(path.join(__dirname,'./static')));
<link rel="stylesheet" href="<something_here>/css/style.css">
<link rel="stylesheet" href="<something_here>/css/style.css">
You don't need to add '/' in the path:
<link rel="stylesheet" type="text/css" href="css/style.css">
Also, you should make a change in your app file:
app.use(express.static(__dirname + '/static'));
This way express knows from where it has to serve the static files.
You are serving the static folder at /public endpoint. So you should change the link to
<link rel="stylesheet" type="text/css" href="/public/css/style.css">
and
<script src="/public/js/script.js"></script>
Also check the name of the css file.
Alright guys, I've been following the fcc node js tutorial for beginners. I have trouble getting the use() function from the express framework to work. I followed all the steps (I've copied exactly what he's doing), but when I open the Chrome/Firefox debug console my I can see my folders are not swapped for the alias I've set (is 'static' instead of 'public'). For anyone wondering, I'm stuck on this part -> https://youtu.be/-FV-moMWRSA?t=230.
my code:
const path = require('path');
const express = require('express');
const app = express(); //this function returns an object with many functions
app.use('/public', express.static(path.join(__dirname, 'static')));
app.get('/',
(req, res) => {
res.sendFile(path.join(__dirname, 'static', 'index.html'));
});
app.listen(3000);
my html:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<link rel="stylesheet" type="text/css" href="/static/css/main.css">
<script src="/static/js/main.js"></script>
</head>
<body>
<p>Test paragraph</p>
</body>
</html>
anyone know what's going on?
You have wrong paths in your html. Since you're using /public in your middleware, only requests with /public will be looked in the static folder to see if a filewith the requested name exists or not.
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<link rel="stylesheet" type="text/css" href="/public/css/main.css">
<script src="/public/js/main.js"></script>
</head>
<body>
<p>Test paragraph</p>
</body>
</html>
Hope this helps !
I have attached my css file to my html file. And then i run and open page using express in node js. However, the css file does not open when i run the webserver through node js.
html(show.ejs)
<html>
<head>
<link rel="stylesheet" type="text/css" href="assets/css/style.css" media="screen" />
</head>
<body>
<h1> Value is <%= detail %></h1>
</body>
</html>
node js
//required npm
var express = require('express');//express 4.*
var path = require('path');
// define app
var app = express();
// set up template engine
app.set('view engine', 'ejs');
//static files
//app.use('/static', express.static('/public')); //not working
app.use('', express.static(path.join(__dirname, 'public'))); //not working
//app.use(express.static(__dirname + '/public')); //not working
//app.use('/public/assets', express.static('public/assets')); //not working
app.get('/show/:id', function (req, res) {
res.render('./panel/show', {
detail: req.params.id ,
});
//port
app.listen(3000);
my project folder
node_modules
views
panel
show.ejs
public
assets
css
style.css
app.js
package.json
By entering <link rel="stylesheet" type="text/css" href="assets/css/style.css" media="screen" /> You are trying to find the assets folder in your out of public directory.
So, when you / it will find public directory which is statically defined in express server.
<html>
<head>
<link type="text/css" href="/assets/css/styles.css" rel="stylesheet">
</head>
<body>
<h1> Value is <%= detail %></h1>
</body>
</html>
I have a folder structure like below
assets
bootstrap
css
style.css
js
jquery.min.js
views
partials
head.ejs
header.ejs
scripts.ejs
home.ejs
user_registration.ejs
In my app.js file I have set this assets folder like:
var app = express();
app.use('/static', express.static('assets'));
var routes = require('./routes/routes');
In my routes.js file
exports.userLogin = function(req, res){
var userLogin = req.params.userId;
var users = memberData.users;
res.render('user_registration', {
title : 'Welcome',
users : users
});
};
In my head.ejs file
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="static/bootstrap/css/bootstrap.min.css" integrity="sha384-1q8mTJOASx8j1Au+a5WDVnPi2lkFfwwEAa8hDDdjZlpLegxhjVME1fgjWPGmkzs7" crossorigin="anonymous">

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/font-awesome/4.5.0/css/font-awesome.min.css">
<link rel="stylesheet" href="static/css/style.css" type="text/css">
Now inside in user_registration file, I have following code
<!DOCTYPE html>
<html lang="en">
<head>
<% include partials/head.ejs %>
</head>
<body>
<% include partials/scripts.ejs %>
</body>
</html>
By using this my jQuery, bootstrap files that are inside assets folder are not being loaded. But the home.ejs page is working normally.
When I check at the console, the home.ejs page is taking those files in following format
http://localhost:3000/static/bootstrap/css/bootstrap.min.css
whereas user_registration page is taking following format
http://localhost:3000/user_registration/static/bootstrap/css/bootstrap.min.css
I am very new in express.js framework, so I could not figure out how to solve this problem. Can anybody please help me. Thank you.
Problem is here app.use('/static', express.static('assets')); in your code line.
Replace it with
app.use(express.static(path.join(__dirname, 'assets')));
And in your head.ejs file replace bootstrap css calling line
href="static/bootstrap/css/bootstrap.min.css" to href="/bootstrap/css/bootstrap.min.css"
Hop you understand.
The problem is: the href link to static resource should be absolute, not relative. Specifically, in head.ejs it should be:
href="/static/bootstrap/css/bootstrap.min.css"
...
href="/static/css/style.css"
NOT:
href="static/bootstrap/css/bootstrap.min.css"
...
href="static/css/style.css"
As app.use('/static', express.static('assets')); stated, the static assets are hosted under /static namespace (absolute URL starting with /static), it doesn't make any sense to use relative URL any more.

});
I am pretty lost here and any help would be great. I guess I don't understand how to "define" system??
edit: added folder structure
Network output
I would say it's because you are sending the index.html file specifically, and doing a static serve for the stuff in /app. If the systemjs.config.js file was in the /app folder and referenced in the index.html as src='/app/systemjs.config.js' it may work.
-- EDIT: Still not 100% sure what the issue is. I did everything we discussed in it and nothing else. Glad it working though!
