I am learning to use ejs, express, node js. I am having probling my style sheet to my header here is my code and here is a . I am using header and footer as include. Here is my
My app.js-
const express = require("express");
const bodyParser = require("body-parser");
const ejs = require("ejs");
const app = express();
app.set("view engine", "ejs");
app.use(bodyParser.urlencoded({
extended: true
}));
app.use(express.static("public"));
app.get("/", function(req, res) {
res.render("home");
});
app.listen(3000, function() {
console.log("Server started on port 3000");
});
2 things to note here
style.css is an external css file. So you dont need style tags inside that file. It should only contain the css.
In your express app, you have to mention the public directory from which you are serving the static files. Like css/js/image
it can be done by
app.use(express.static(__dirname + '/public'));
assuming you put the css files in public folder from in your app root. now you have to refer to the css files in your tamplate files, like
<link href="/css/style.css" rel="stylesheet" type="text/css">
Here i assume you have put the css file in css folder inside your public folder.
So folder structure would be
.
./app.js
./public
/css
/style.css
close head tag appropriately
Hello guys I dont understand why my css file is not served when the url contains parameters. I want to access a route from another route when I click on the link here : click here located in welcome file.Below is my server config : app.js
let express = require("express");
let path = require("path");
let mongoose = require("mongoose");
let bodyParser = require('body-parser');
let exphbs = require('express-handlebars');
let dotenv = require("dotenv").config();
let app = express();
app.use(express.static(path.join(__dirname,"public")))
app.set("views","views");
app.set("view engine","hbs");
app.engine("hbs",exphbs({
extname:"hbs",
layoutsDir:path.join(__dirname,"views"),
defaultLayout:"template",
partialsDir:path.join(__dirname,"views/partials/")
})) ;
######ROUTING
app.get("/",(req,res)=>{
res.render("welcome") // from which I access "/books/:id" route : css file is served
})
app.get("/books/:id",(req,res)=>{
let p_id = req.params.id;
//here css file is not served but if I access without parameter,css file is served so WHY??????
res.render("bookdetail")
})
NB : my css file is called home.css
My template file template.hbs
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" type="text/css" href="home.css">
<title>ziri book</title>
</head>
<body>
{{{body}}}
</body>
</html>
CSS files are not loading and on inspecting element(F12) and going to Networks, my CSS file is not visible.
I have added the middleware
app.use(express.static(path.join(__dirname, '/public')));
and also required path above it.
I have added the middleware, required it and npm installed it too.
My Folder Structure
-app.js
-package.json
-package-lock.json
-node_modules
-public
-stylesheets
-main.css
-views
-index.ejs
-partials
-header.ejs
-footer.ejs
My Header.ejs file has this and my body containing some text.
<link href="/stylesheets/main.css">
My app.js file is
var express = require('express');
var request = require('request');
var ejs = require('ejs');
var path = require('path');
var app = express();
app.set('view engine', 'ejs');
app.use(express.static(path.join(__dirname, '/public')));
and my css file changes the color of backgorund, index.ejs file calls the header and footer respectively
<% include partials/header%>
My css code
body{
background-color: purple;
text-align: center;
}
My chrome console shows no error and still I am not able to upload my CSS.
Thanks in advance for your inputs.
You are using the link tag wrong.
You need to supply rel and type attributes for it to load the css and parse it properly. Check out the documentation of link tag to know more
The problem is with the link tag. You have to specify rel, type and href attributes in your link tag.
<link rel = "stylesheet" type = "text/css" href = "/stylesheets/main.css" />
The mater is that your are requesting stylesheet file given an url who will be completed by navigator with the current root path.
For instance, this is your link below.
<link rel="stylesheet" href = "/stylesheets/main.css" />
This is your NodeJS server code.
app.get("/your/root/path", (req, res)=>{
})
Your href link will correspond to /your/root/path/stylesheets/main.css
I think that it will be your problem.
If so, to correct it, set <base> url for static files or don't let your routes path who return views to be in the form /your/root/path but instead /your-root-path
I'm creating a simple page to start to learn HTML, CSS and java script. I have my HTML file with the following link to my CSS file but for some reason none of CSS loads.
I running this on localhost via node.
html:
<!DOCTYPE html>
<html>
<head>
<link href='./css/styles.css' type='text/css' rel='stylesheet'>
</head>
my server.js file:
var http = require('http');
var fs = require('fs');
const PORT=8080;
fs.readFile('./index.html', function (err, html) {
if (err) throw err;
http.createServer(function(request, response) {
response.writeHeader(200, {"Content-Type": "text/html"});
response.write(html);
response.end();
}).listen(PORT);
});
I also get the error
"Resource interpreted as Stylesheet but transferred with MIME type
text/html: "http://localhost:8080/css/styles.css"."
Do I need to add another content-type for "text/css" into my server.js file?
Document tree:
You can add your scripts externally to your html page like this. It could be located inside of the head tags like your CSS definition.
<script type="text/javascript" src="../Script_folder/server.js"></script>
And be carefull about reaching files in the tree. ../ means one level up and ~/ points to root node. So, I wonder that your routing has a certain point with a single . in your CSS address.
<link href='../css/styles.css' type='text/css' rel='stylesheet'>
with two dots. ../
In href attribute you used only one dot instead of two. Your href should be like
<link href='../css/styles.css' type='text/css' rel='stylesheet'>
I'm trying to follow the instructions to https://stackoverflow.com/a/18633827/2063561, but I still can't get my styles.css to load.
From app.js
app.use(express.static(path.join(__dirname, 'public')));
In my .ejs, I have tried both of these lines
<link rel="stylesheet" type="text/css" href="/css/style.css" />
<link rel="stylesheet" type="text/css" href="/public/css/style.css" />
Neither loads the css. I've gone into the developer's console noticed the type is set to 'text/html' instead of 'text/css'.
My path looks like
.
./app.js
./public
/css
/style.css
Use this in your server.js file
app.use(express.static(__dirname + '/public'));
and add css like
<link rel="stylesheet" type="text/css" href="css/style.css" />
dont need / before css like
<link rel="stylesheet" type="text/css" href="/css/style.css" />
1.Create a new folder named 'public' if none exists.
2.Create a new folder named 'css' under the newly created 'public' folder
3.create your css file under the public/css path
4.On your html link css i.e
<link rel="stylesheet" type="text/css" href="/css/style.css">
// note the href uses a slash(/) before and you do not need to include the 'public'
5.On your app.js include :
app.use(express.static('public'));
Boom.It works!!
The custom style sheets that we have are static pages in our local file system. In order for server to serve static files, we have to use,
app.use(express.static("public"));
where,
public is a folder we have to create inside our root directory and it must have other folders like css, images.. etc
The directory structure would look like :
Then in your html file, refer to the style.css as
<link type="text/css" href="css/styles.css" rel="stylesheet">
For NodeJS I would get the file name from the res.url, write the header for the file by getting the extension of the file with path.extname, create a read stream for the file, and pipe the response.
const http = require('http');
const fs = require('fs');
const path = require('path');
const port = process.env.PORT || 3000;
const server = http.createServer((req, res) => {
let filePath = path.join(
__dirname,
"public",
req.url === "/" ? "index.html" : req.url
);
let extName = path.extname(filePath);
let contentType = 'text/html';
switch (extName) {
case '.css':
contentType = 'text/css';
break;
case '.js':
contentType = 'text/javascript';
break;
case '.json':
contentType = 'application/json';
break;
case '.png':
contentType = 'image/png';
break;
case '.jpg':
contentType = 'image/jpg';
break;
}
console.log(`File path: ${filePath}`);
console.log(`Content-Type: ${contentType}`)
res.writeHead(200, {'Content-Type': contentType});
const readStream = fs.createReadStream(filePath);
readStream.pipe(res);
});
server.listen(port, (err) => {
if (err) {
console.log(`Error: ${err}`)
} else {
console.log(`Server listening at port ${port}...`);
}
});
Use in your main .js file:
app.use('/css',express.static(__dirname +'/css'));
use in you main .html file:
<link rel="stylesheet" type="text/css" href="css/style.css" />
The reason you getting an error because you are using a comma instead of a concat + after __dirname.
In your app or server.js file include this line:
app.use(express.static('public'));
In your index.ejs, following line will help you:
<link rel="stylesheet" type="text/css" href="/css/style.css" />
I hope this helps, it did for me!
IMHO answering this question with the use of ExpressJS is to give a superficial answer. I am going to answer the best I can with out the use of any frameworks or modules. The reason this question is often answerd with the use of a framework is becuase it takes away the requirment of understanding 'Hypertext-Transfer-Protocall'.
The first thing that should be pointed out is that this is more a problem surrounding "Hypertext-Transfer-Protocol" than it is Javascript. When request are made the url is sent, aswell as the content-type that is expected.
The second thing to understand is where request come from. Iitialy a person will request a HTML document, but depending on what is written inside the document, the document itsself might make requests of the server, such as: Images, stylesheets and more. This question refers to CSS so we will keep our focus there. In a tag that links a CSS file to an HTML file there are 3 properties. rel="stylesheet" type="text/css" and href="http://localhost/..." for this example we are going to focus on type and href. Type sends a request to the server that lets the server know it is requesting 'text/css', and 'href' is telling it where the request is being made too.
so with that pointed out we now know what information is being sent to the server now we can now seperate css request from html request on our serverside using a bit of javascript.
var http = require('http');
var url = require('url');
var fs = require('fs');
function onRequest(request, response){
if(request.headers.accept.split(',')[0] == 'text/css') {
console.log('TRUE');
fs.readFile('index.css', (err, data)=>{
response.writeHeader(200, {'Content-Type': 'text/css'});
response.write(data);
response.end();
});
}
else {
console.log('FALSE');
fs.readFile('index.html', function(err, data){
response.writeHead(200, {'Content_type': 'text/html'});
response.write(data);
response.end();
});
};
};
http.createServer(onRequest).listen(8888);
console.log('[SERVER] - Started!');
Here is a quick sample of one way I might seperate request. Now remember this is a quick example that would typically be split accross severfiles, some of which would have functions as dependancys to others, but for the sack of 'all in a nutshell' this is the best I could do. I tested it and it worked. Remember that index.css and index.html can be swapped with any html/css files you want.
I have used the following steps to resolve this problem
create new folder (static) and move all js and css file into this folder.
then add app.use('/static', express.static('static'))
add css like <link rel="stylesheet" type="text/css" href="/static/style.css"/>
restart server to view impact after changes.
Use this in your server.js file
app.use(express.static('public'));
without the directory ( __dirname ) and then within your project folder create a new file and name it public then put all your static files inside it
Its simple if you are using express.static(__dirname + 'public') then don't forget to put a forward slash before public that is express.static(__dirname + '/public') or use express.static('public') its also going to work;
and don't change anything in CSS linking.
the order of registering routes is important . register 404 routes after static files.
correct order:
app.use("/admin", admin);
...
app.use(express.static(join(__dirname, "public")));
app.use((req, res) => {
res.status(404);
res.send("404");
});
otherwise everything which is not in routes , like css files etc.. , will become 404 .
The above responses half worked and I'm not why they didn't on my machine but I had to do the following for it work.
Created a directory at the root
/public/js/
Paste this into your server.js file with name matching the name of directory created above. Note adding /public as the first param
app.use('/public',express.static('public'));
Finally in the HTML page to which to import the javascript file into,
<script src="public/js/bundle.js"></script>
