Question

How do i check the existence of a file?

In the documentation for the module fs there\'s a description of the method fs.exists(path, cal

Answer 1

Old Version before V6: here's the documentation

  const fs = require('fs');    
  fs.exists('/etc/passwd', (exists) => {
     console.log(exists ? 'it\'s there' : 'no passwd!');
  });
// or Sync

  if (fs.existsSync('/etc/passwd')) {
    console.log('it\'s there');
  }

UPDATE

New versions from V6: documentation for fs.stat

fs.stat('/etc/passwd', function(err, stat) {
    if(err == null) {
        //Exist
    } else if(err.code == 'ENOENT') {
        // NO exist
    } 
});
