Leveraging the Power of CSS in Your Express Applications

Struggling to make my CSS links functional while working on localhost. Currently, when I view Index.html on my server, it displays as plain text without any styling. Even after trying the express middleware, the CSS files are still not being served, resulting in a 404 error. Here is the snippet of code causing the issue:

App.js:

app.set('view engine', 'html');
app.engine('html', hbs.__express);


app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
app.use(express.static(path.join(__dirname, 'Public')));

Index.html:

<head>
<meta charset="utf-8">
<meta http-equiv="Content-Type" content="text/html">
<link rel="stylesheet" type="text/css" media="all" href="/styles.css">
<link rel="stylesheet" type="text/css" media="all" href="/switchery.min.css">
<script type="text/javascript" src="/switchery.min.js"></script>
</head>

//UPDATE//

Realized my mistake with path.join argument setup. Grateful for the input provided. The corrected code that resolved the issue is shown below:

app.use(express.static(path.join(__dirname + '/public')));

Answer №1

To ensure consistency, it's important to rename your folder from Public to public. It is recommended not to use capital letters when naming folders.

Also, update the code to:

app.use(express.static(__dirname + '/public'));

Answer №2

According to MaximeF, it is recommended to use lower-case or camelCase for naming folders. It's important to have a well-organized structure in your public directory. For instance, if your CSS file is located inside a folder within the public directory, such as public/css/styles.css, you must specify the full path relative to public when linking it in your HTML document. In this scenario, the correct link would be

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