The application rejected the styling from 'http://localhost:3000/css/style.css' due to its unsupported MIME type ('text/html') for a stylesheet

While working on an example website template, I encountered an error in the Chrome console:

Refused to apply style from 'http://localhost:3000/css/style.css' because its MIME type ('text/html') is not a supported stylesheet MIME type, and strict MIME checking is enabled.

Every time I try to load the css/style.css page, I get a 404 error even though the path appears to be correct. Below is a snippet of the basic code for the website:

Node.js App:

var express = require('express');
var app = express();

var exphbs  = require('express-handlebars');
var path = require('path');

app.engine('hbs', exphbs({extname:'hbs'}));
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'hbs');

app.use(express.static(path.join(__dirname, "static")));

app.get('/', function(req, res) {
  res.render('resume.hbs')
})

app.listen(3000)

HTML Structure:

<!DOCTYPE html>
<html lang="en" dir="ltr">
  <head>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet" integrity="sha384-BVYiiSIFeK1dGmJRAkycuHAHRg32OmUcww7on3RYdg4Va+PmSTsz/K68vbdEjh4u" crossorigin="anonymous">
    <base href="/">
    <link rel="stylesheet" href="..\css\style.css" type = "text/css">
    <title>Example Website</title>
    <h1>Header</h1>
    <hr id = 'headerBorder'>
  </head>
  <body>
  </body>
</html>

CSS Styling:

h1 {
 color: blue
}

I have attached the folder structure images below, which clearly display the path. Despite this, the issue persists. Any suggestions would be greatly appreciated!

Answer №1

The issue at hand is most likely due to the absence of the anticipated path.

Within your code, you are utilizing this particular line:

app.use(express.static(path.join(__dirname, "static")));

To resolve this, ensure that you have a directory named "static" and within it, place your CSS and images. You can then reference them like so:

<link rel="stylesheet" href="/css/style.css" type="text/css">

Answer №2

When working with hbs, it is recommended to create a "public" folder to store your static folders containing CSS, JavaScript, and images. You can then use the following code:

const path = require("path");

app.use(express.static(path.join(__dirname, "public")));

An important aspect of this setup is that by specifying "public" as a static folder, hbs will treat it as the root folder when referencing files within it. For example, if you have a main.css file in a "style" folder inside the "public" folder, the directory would be "public/style/main.css". When linking main.css, you would use:

<link rel="stylesheet" href="style/main.css" type="text/css" />

Additionally, here is the complete configuration for using hbs in express:

app.set("view engine", "hbs");
app.engine(
  "hbs",
  expressHbs({
    defaultLayout: "layout",
    extname: ".hbs",
    layoutsDir: __dirname + "/views/layouts",
    partialsDir: __dirname + "/views/partials"
  })
);

Answer №3

Ensure that all your CSS files are neatly organized within a designated folder named static or public.
By doing so, your CSS file can be easily located at public/css/style.css.
To reference static files in your app.js, use the following code:

app.use(express.static(path.join(__dirname, "public")));

It's crucial to note that the path of the public folder must be relative to the location of the app.js file.

Answer №4

To organize your static files, create a folder named "static" and place your css and image folders within it. Make sure to first create a css folder for all your css files and an image folder for all images. Here's the code snippet: app.use(express.static(path.join(__dirname, "static"))); By specifying the 'static' folder in this code, you are instructing express to look for static files there. If the folder doesn't exist, you will encounter errors and your website won't apply the css and images properly.

Answer №5

Sol: To begin, start by creating a 'static' folder and moving the css folder into it. Next, in the html file:

<!DOCTYPE html>
<html lang="en" dir="ltr">
  <head>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet" integrity="sha384-BVYiiSIFeK1dGmJRAkycuHAHRg32OmUcww7on3RYdg4Va+PmSTsz/K68vbdEjh4u" crossorigin="anonymous">
    <base href="/">
    <link rel="stylesheet" href="css\style.css" type = "text/css">
    <title>Example Website</title>
    <h1>Header</h1>
    <hr id = 'headerBorder'>
  </head>
  <body>
  </body>
</html>

For the Javascript file:

var express = require('express');
var app = express();

var exphbs  = require('express-handlebars');
var path = require('path');

app.engine('hbs', exphbs({extname:'hbs'}));
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'hbs');

app.use(express.static("static"));

app.get('/', function(req, res) {
  res.render('resume.hbs')
})

app.listen(3000)

Answer №6

I attempted to modify the various slashes, but this did not completely resolve the issue. It is likely that the bootstrap CSS also defines h1. Therefore, you must adjust the sequence of the CSS files in your HTML:

<!DOCTYPE html>
<html lang="en" dir="ltr">
  <head>
    <meta charset="utf-8">
        <meta name="viewport" content="width=device-width, initial-scale=1">
    <link rel="stylesheet" href="../css/style.css" type="text/css">
    <link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet" integrity="sha384-BVYiiSIFeK1dGmJRAkycuHAHRg32OmUcww7on3RYdg4Va+PmSTsz/K68vbdEjh4u" crossorigin="anonymous">
    <base href="/">
    <title>Example Website</title>
    <h1>Header</h1>
    <hr id = 'headerBorder'>
  </head>
  <body>
  </body>
</html>

Simply adding !important to your CSS will not resolve the issue.
