Add gulp task to watch

[adamfchs]

This is more a question and not an issue—wasn't sure where to post.

I've created a gulp task that will gzip the style.css which immediately gains 4-5 points in Google Page speed:

gulp.task('compress', function() {
gulp.src('./dist/*.css')
.pipe(gzip())
.pipe(gulp.dest('./dist'));
});

gulp.task('zip', ['css', 'compress']);

Its working fine, but I would like to plug it into the watch/compile process run with 'npm start' so that when the style.css gets automatically compiled, it gets automatically zipped as well.

Any direction on how I can go about doing this? This is my current npm start: "start": "gulp compile && gulp theme && gulp zip", zip is not working on style change
