CODE EXAMPLE FOR JAVASCRIPT

Serving static files in Express

var express = require('express');
var app = express();
var path = require('path');

// For example, use the following code to serve images, CSS files, and JavaScript files in a directory named public:
app.use(express.static('public'))

// To use multiple static assets directories, call the express.static middleware function multiple times:
app.use(express.static('public'))
app.use(express.static('files'))

// To create a virtual path prefix (where the path does not actually exist in the file system) for files that are served by the express.static function, specify a mount path for the static directory, as shown below:

app.use('/static', express.static('public'))

// However, the path that you provide to the express.static function is relative to the directory from where you launch your node process. If you run the express app from another directory, it’s safer to use the absolute path of the directory that you want to serve:

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