Gulp, how to start a task for rebuilding when deleting a file with watch?

Question

gulp.js

Good evening!
I don’t understand why it doesn’t perform the task when it is deleted.
console.log is executed when the file is deleted, but how can the task be restarted for reassembly?

gulp.watch('./source/**/*.{styl,css}', gulp.series('style')).on('unlink', function() {
  return gulp.series('style');
});

Answer 1

If I understand your code correctly, then you need a command gulp.start("Task name")
Something like this...

gulp.watch('./source/**/*.{styl,css}', gulp.series('style')).on('unlink', function() {
  gulp.start("rebuild");
  return gulp.series('style');
});

The standard gulp.watch does not know how to watch new or deleted files. Try using gulp-watch
