Using Vue SPA distributed by Express.
this is my helmet code in express
app.use(helmet.contentSecurityPolicy({
directives: {
defaultSrc: ["'self'"],
styleSrc: ["'self'","'unsafe-inline'" ,'unpkg.com', 'cdn.jsdelivr.net',
'fonts.googleapis.com', 'use.fontawesome.com'],
scriptSrc: ["'self'","'unsafe-inline'",'js.stripe.com'],
frameSrc: ["'self'",'js.stripe.com'],
fontSrc:["'self'",'fonts.googleapis.com','fonts.gstatic.com','use.fontawesome.com','cdn. joinhoney.com']
}
}));
Doing this produces no errors in the browser console but my page loads blank , am I missing something ?
Here is the stuff i'm trying to import in my index.html
<script src="https://js.stripe.com/v3/"></script>
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/animate.css#3.5.2/animate.min.css">

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);

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 hosted a MERN app which uses webpack on heroku. React Routing works fine on local host. But on heroku, when I click refresh on /any-path page is blanked out.
Console shows an error "The character encoding of the plain text document was not declared. The document will render with garbled text in some browser configurations if the document contains characters from outside the US-ASCII range. The character encoding of the file needs to be declared in the transfer protocol or file needs to use a byte order mark as an encoding signature."

Thanks for taking the time to read my question. My website works fine when I run ng serve. When I run ng build --prod, that works fine as well. Problem is, when I try to render index.html in dist im getting 404 errors. The errors are 404 errors for my main, styles, and polyfill files. I'm trying to build a back end so that I can process card payments. Any help would be appreciated - have been knocking my head against the wall for hours now with no resolve. This is my code below:
server.js
var express = require('express');
var app = express();
var server = require('http').Server(app);
var bodyParser = require('body-parser');
app.use(express.static(__dirname));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({extended: true}));
server.listen(2000, function(){
console.log('Listening on 2000..')
});
console.log(__dirname);
app.get('/', (req, res) => {
res.sendFile(__dirname + '/dist/culture/index.html');
});

Again, in short, localhost is giving 200 code which is good it means its connecting to the right place. The problem is once it is connected it can not find any files. What am I doing wrong? Thanks
You must correct this line of code: app.use(express.static(__dirname)); to something like this: app.use(express.static(path.join(__dirname, 'dist/culture'))); if your Angular app files are in dist/culture directory.
Main problem is that when your index.html for example tries to load <link rel="icon" type="image/x-icon" href="favicon.ico"> it uses request to path http://localhost:2000/favicon.ico. Your express backend have defined static assets on __dirname and your actual app is in dist/culture so your request should look like http://localhost:2000/dist/culture/favicon.ico.
Applied change has improved configuration of static files location.
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 got an Angular2 project that was developed by a different person and I need to run it. When I do, using npm start I get the server to run but the component, called my-app is not rendering on the page.
This is the index.html:
<html>
<head>
<base href='/'>
<title></title>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="styles.css">
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet">
<link href="c3.css" rel="stylesheet" type="text/css">
</head>
<body>
<my-app>Loading......</my-app>
</body>
</html>
This is app.components.ts:
import { Component } from '#angular/core';
import { AuthenticationService } from './authentication.service';
import { Router } from '#angular/router';
#Component({
selector: 'my-app',
templateUrl: 'app/app.component.html',
styleUrls: ['app/app.component.css']
})
export class AppComponent {
title = '';
isProd:boolean;
constructor(private authenticationService: AuthenticationService, private router: Router) {
this.isProd = false;
}
In the template for my-app, which is app/app.component.html I put a simple div for testing:
<div><h1>app components</h1></div>
When running this I can see the Loading..... which is in index.html but not the contents of app/app.component.html.
What am I missing?
I can't see if you are loading angular and your transpiled ts anywhere in index.html. You need to load all required dependeny for run angular2 app in index.html and allso your transpiled ts.
Note:- you need to put base tag after all you link to load css.
