Yes, using node:

const fs = require('fs');
const dir = './directory';

fs.readdir(dir, (err, files) => {
  console.log(files.length);
});

Instead of copying the code, flag as a duplicate. The same answer doesn't help. – Andrew Li Dec 04 '17 at 14:02

Since javascript doesn't have local filesystem access when run in the browser, there is no way to access local files from javascript. If you are asking about accessing all files hosted on a cdn or something similar in that directory, there is still no way to tell which requests will return a 20x.

If you are using nodejs, use the fs.readdir function:

const fs = require('fs');

fs.readdir('app/test/vehicle/', (err, files) => {
  files.forEach(file => { console.log(file);} );
})

There is no way to access the file system from a web page.

If you are using nodejs, then you can use fs.readdir or fs.readdirSync:

const fs = require('fs');
const dir = './directory';

fs.readdir(dir, (err, files) => {
   console.log(files.filter(file => file.endsWith(".js")).length);
});

Where are you trying to get list of the files? On the client side it is impossible. JavaScript does not have access to the client file system. If you are trying to do it in the server side using for example node.js then you can do something like:

var filesys = require('fs');
var files = filesys.readdirSync('/app/test/vehicle/');
