How to inject a comment in javascript files using gulp

Question

I try to add a header to every js-file in my project.

The current files are without comments in header. I want a gulp-task to insert following header to the files:

/*
 * New Comment from Gulp-Task
 */

Is there a plugin, already ? Gulp-Inject is maybe the solution, but I don´t know, how to use it for javascript injection.

This is not a straight answer to your question as it requires some translation to your case, but here is a post on how to update version numbers (in your case, something else) within javascript files.

The second part to this answer is where you'll find your clue.

okay, that was a basic approach. But I think, I needn´t to replace but add something in head. – Dominik Apr 19 '16 at 08:47
Okay I found a package, called gulp-insert. Thereby it is possible to add a header =) – Dominik Apr 19 '16 at 09:07

I found the solution that work for me:

gulp.src(['./**/*.js'])
    .pipe(insert.prepend(license))
    .pipe(gulp.dest('./'));

It prepend a license head to every .js files in this directory and sub folders.
