Here is how to use the fs module list the files (and directories) in the current directory in Node.js …

var fs = require('fs');

This is a blocking call. Because it is synchronous. It is generally more preferable to do in asynchronous mode as in …

var fs = require('fs');
fs.readdir(__dirname, function(err,files) {

In this case, the “Done” will be printed first before the list of files.
