What is serve-static?

The serve-static npm package is used to serve static files such as images, CSS files, and JavaScript files. It is built on top of the core 'http' module in Node.js and provides a middleware that can be used with frameworks like Express to serve files from a directory in the file system.

What are serve-static's main functionalities?

Basic static file serving

This code sample demonstrates how to serve static files from a directory named 'public'. When a request is made to the server, it will look for files in this directory to serve.

const express = require('express');
const serveStatic = require('serve-static');

const app = express();

app.use(serveStatic('public'));

app.listen(3000);

Customizing cache control

This code sample shows how to customize cache control headers for the files served. The 'maxAge' option sets the cache control max-age directive in seconds, and the 'setHeaders' function allows for further customization of the headers.

const express = require('express');
const serveStatic = require('serve-static');

const app = express();

app.use(serveStatic('public', {
  maxAge: '1d',
  setHeaders: function (res, path) {
    res.setHeader('Cache-Control', 'public, max-age=86400')
  }
}));

app.listen(3000);

Serving files from multiple directories

This code sample demonstrates how to serve static files from multiple directories. The first 'serveStatic' serves files from the 'public' directory, while the second one serves files from the 'media' directory under the '/media' path.

const express = require('express');
const serveStatic = require('serve-static');

const app = express();

app.use(serveStatic('public'));
app.use('/media', serveStatic('media'));

app.listen(3000);
