I am having an issue with some custom routing code, it all works fine and is in sync with the client-side view routing I do, but as soon as I have a subpage, it doesn’t route my static files correctly.

Failed to load module script: Expected a JavaScript module script but the server responded with a MIME type of "text/html". Strict MIME type checking is enforced for module scripts per HTML spec.

Rather than giving me a file from the root directory, it’ll serve it as if it were from the subfolder.

Example: i go to http://localhost/sign-up, and files loading in my index file from /scripts are loaded, but if i go to http://localhost/sign-up/2, it’ll attempt to load the script from /sign-up/scripts

const express = require('express');
const path = require('path');

const app = express();

app.use('/views', express.static(path.resolve(__dirname, 'frontend', 'views')));

app.use('/styles', express.static(path.resolve(__dirname, 'frontend', 'styles')));
app.use('/scripts', express.static(path.resolve(__dirname, 'frontend', 'scripts')));
app.use('/media', express.static(path.resolve(__dirname, 'frontend', 'media')));

app.get('/*', (req, res) => {
    res.sendFile(path.resolve(__dirname, 'frontend', 'newSite.html'));
});

app.listen(process.env.PORT || 1234, () => console.log('Server is now running...'));

To manage this I have been following these tutorials by DCODE on youtube, but I can’t see anything amiss:

>Solution :

Resources loaded in the sign up folder should use URLs beginning with a ‘/‘ character, to make them relative to the site root, e.g.

src="/scripts/modulefile.js"
href="/css/stylesheet.css"
href="/media/image.png"

and not urls relative to the signup folder – which they will be if the leading '/' is omitted.
