Using the fs module to list a directory in Node.js

Posted in Articles

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

var fs = require('fs');
console.log(fs.readdirSync(__dirname));
console.log("Done");

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) {
	console.log(files);							   
});
console.log("Done");

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