I am using handlebars template in express and node. But seems like it cannot apply style in my template
here is my directory:
my template
<html lang="en">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>RYZE Report</title>
<link rel="stylesheet" href="./css/style.css" >
</head>
<body>
<h1>Hello hi</h1>
</body>
</html>
and in my app.js, I have this line
app.use(express.static(__dirname + '/public'))
Thank you
I have looked at the code and I made a couple of improvements to make this work, instead of compiling the document without any inputs, I have made a css input as the following in the template.hbs:
<head>
<!-- Required meta tags -->
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<style>
{{css}}
</style>
<title>Hello, world!</title>
I have also edited the app.js to read the css along with the html and embed the css into it like so: app.js:
const template = fs.readFileSync('template.hbs', 'utf8');
const css = fs.readFileSync('./public/css/style.css', 'utf-8');
const DOC = Handlebars.compile(template);
and used the DOC as following:
DOC({css})
this will inline the css inside of the hbs file, I hope this answers your question

You have typo in your syntax.
Try this.
video.addEventListener.
You are missing e from Listener
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);
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>
<link rel="stylesheet" type="text/css" href="/static/css/style.css">
</head>
<body>
<div class="asd">
Hi xyz here..
</div>
<script src="/static/js/script.js"></script>
</body>
</html>
folder structure is:
static
css
main.css
js
script.js
index.html
app.js
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.
I recently took a course on back-end web developing.
As the title says, I don't get how can I use a header partial for the whole website but have different titles for each page. (because is included in the tag)
Is there any trick?
1st) In your Express route:
app.get("/", function(req, res){
res.locals.title = "Abel's Home Page"; // THIS LINE IS KEY
res.render("home.ejs");
});
2nd) In your views/home.ejs file:
<% include partials/header.ejs %>
3rd) In your views/partials/header.ejs file:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title><%= title %></title> <!-- THIS LINE IS KEY -->
<link rel="stylesheet" href="../style.css">
<link rel="shortcut icon" href="../logo_sm.png" type="image/x-icon">
</head>
<body>
Each page that includes the partial is free to pass data to said partial through parameters. See here for an example.
use html-webpack-plugin output html page , but in output page lost body inner html element , like <div id="app"></div> , here is my input output and webpack.config file :
input
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0, user-scalable=0, minimum-scale=1.0, maximum-scale=1.0">
<link rel="icon" href="static/pic/logo.png" type="image/x-icon">
<link rel="stylesheet" href="static/weui/weui.min.css">
<link rel="stylesheet" href="static/index.css">
<title>APP</title>
</head>
<body>
<div id="app"></div>
<script src="./dist/vendor.js"></script>
<script src="./dist/app.js"></script>
</body>
</html>
output
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>SPA</title>
<link href="/dist/style.df241090c6a9e0a6bf26.css" rel="stylesheet"></head>
<body>
<script type="text/javascript" src="/dist/vendor.df241090c6a9e0a6bf26.js"></script><script type="text/javascript" src="/dist/app.df241090c6a9e0a6bf26.js"></script></body>
</html>
part webpack.config.js
const htmlWebpackPlugin = require('html-webpack-plugin');
plugins: [
new htmlWebpackPlugin({
title:'SPA',
filename: 'assets/index.html'
})
],
The filename option is simply used as the output file, it won't read and modify the existing file, if one exists. Because if it did that, every new build would just append to it, unless you cleaned it manually. To use your input as the base, you need to use it as a template.
new htmlWebpackPlugin({
title:'SPA',
filename: 'assets/index.html',
template: 'path/to/template/index.html'
})
The template should not be the same as the output filename, otherwise it gets overwritten. See also Writing Your Own Templates. The template can be a regular HTML file and it will inject the necessary assets.
