Delete a file asynchronously:

var fs = require('fs');

fs.unlink('/path/to/file.txt', function(err) {
  if (err) throw err;

  console.log('file deleted');
});

You can also delete it synchronously*:

var fs = require('fs');

fs.unlinkSync('/path/to/file.txt');
console.log('file deleted');

• avoid synchronous methods because they block the entire process until the execution finishes.
