Node's del command - callback not firing

Question

I\'m working through a pluralsight course on gulp. John Papa is demonstrating how to inject a function that deletes existing css files, into the routine that compiles the n

Answer 1

del isn't a Node's command, it's probably this npm package. If that's the case it doesn't receive a callback as second parameter, instead it returns a promise and you should call .then(done) to get it called after the del finishes.

Update

A better solution is to embrace the Gulp's promise nature:

Change your clean function to:

function clean(path) {
  return del(path); // returns a promise
}

And your clean-styles task to:

gulp.task('clean-styles', function(){
  var files = config.temp + '/**/*.css';
  return clean(files);
});
