What do I return from my Gulp task if I decide to do nothing?

Question

Suppose my gulp task decides to do nothing -- what should I return?

gulp.task 'maybe_transform_files', ->
    if check_something()
        gulp.src('src')
            .pipe transform_files()
            .pipe gulp.dest('target')
    else
        return something

In other situations, I might use the done() callback, but I don't think I can use it here, where I might return a stream.

Answer 1

An old post, but no extra node package required now. gulp.src('.') should work just fine, as @Nick Perkins mentioned.

Answer 2

have a look at gulp-nop

what you can do to have no-op is

var nop = require('gulp-nop');

.....

return gulp.src('.').pipe(nop());

or if you are using gulp-util you can use noop, similarly
