It's very easy to serve static content in Express by using express.static built-in middleware function. For example, to make all assets publicly available from /public directory i.e. http://localhost:3000/images/kitten.jpg, http://localhost:3000/css/style.css, declare a route as such:
app.use(express.static('public'));To use multiple static assets directories, simply declare the express.static middleware function multiple times:
app.use(express.static('public'));
app.use(express.static('files'));It is also possible to create a virtual path prefix. For example, you can serve static files from /public directory but use prefix /static as such:
app.use('/static', express.static('public'));Now the files from /public directory are accessible by http://localhost:3000/static/images/kitten.jpg, http://localhost:3000/static/css/style.css, etc.
