How do I configure static files in my Express app?

You can use the express.static middleware to serve static files. First, require the path module and then set it up like this:

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

const app = express();
app.use(express.static(path.join(__dirname, 'public')));

This will serve files from the 'public' directory.

What types of files can I serve as static files?

You can serve any type of file as static files, including HTML, CSS, JavaScript, images, and fonts. Just place them in the directory you specified.

Can I serve files from multiple directories?

Yes, you can use multiple express.static middleware calls to serve files from different directories. Just add them one after the other.

Is there a way to set cache control for static files?

Yes, you can set cache control by passing options to express.static. For example:

app.use(express.static('public', { maxAge: '1d' }));

This sets the cache duration to one day.
