Serving static files is essential for delivering frontend assets, images, stylesheets, and JavaScript files in Node.js web applications and API servers. As the creator of CoreUI, a widely used open-source UI library, I’ve configured static file serving in numerous Node.js applications for delivering CoreUI assets, documentation sites, and enterprise dashboard frontends. From my expertise, the most efficient approach is to use Express.js built-in static middleware. This method provides optimized file serving, proper caching headers, and security features while handling common web server tasks automatically.
