copy and keep original folder structure

i have a list of files to copy:

    gulp.src([list of js files])
      .pipe(gulp.dest(build_dir))

the files are copied, but flattened. how can i reserve original directory structure? i can’t find an option for that

If you want to keep the sub-folders, you have to define the base in the options (2nd argument) e.g., to keep “assets/file.doc” in “dist/”:

    gulp.src(["assets/file.doc"], {base: "."})
        .pipe(gulp.dest("dist/"));

We are allowing functions in gulp.dest so you could do this

gulp.dest(function(file){
  return path.join(build_dir, path.dirname(file.path));
});
