How to Fix CSS File Loading Issues in Express-EJS Applications: Why is My CSS Not Being Loaded?

Integrating CSS Files into Express-EJS Applications Using Node.js

When customizing a Node.js-Express application, including CSS styles is crucial for enhancing the user interface. Users may encounter difficulties when attempting to incorporate CSS files into their application. This article will explore a common problem faced by developers and provide a detailed solution.

Issue: CSS File Loading Failure

One common issue that developers encounter is the inability to load CSS files into their EJS-based Express-JS application. This can be particularly frustrating when the code seems to be implemented correctly.

Despite using the recommended approach of setting up static asset serving using express.static() middleware, the expected CSS files might not be loaded. Additionally, the developer's console may indicate that the loaded file has its type set as 'text/html' instead of the intended 'text/css.'

Solution: Correcting the File Path

To resolve this issue, ensure that the path specified for serving static files in the express.static() method is correct. In the provided code sample, it's crucial to replace path.join(__dirname, 'public') with __dirname '/public'. This change will accurately reference the location of the CSS file.

Consequently, the CSS file reference in your EJS template should be modified to use a relative path, such as css/style.css, without the leading slash.

By making these adjustments, Node.js will successfully serve your CSS file with the correct MIME type, ensuring that it's properly loaded and applied to your application's HTML.
