var fs = require('fs');
fs.stat('path/to/file', function(err) {
 if (!err) {
 console.log('file or directory exists');
 }
 else if (err.code === 'ENOENT') {
 console.log('file or directory does not exist');
 }
});

Synchronously

Here, we must wrap the function call in a try/catch block to handle error.



var fs = require('fs');
try {
 fs.statSync('path/to/file');
 console.log('file or directory exists');
}
catch (err) {
 if (err.code === 'ENOENT') {
 console.log('file or directory does not exist');
 }
}

With all that being said, I highly recommend you keep learning!
