gulp - How to deal with dependencies when deploying a node.js app? -

i'm setting gulp build file node.js project , don't have experience either of them.

so i'm doing copying code deployment directory, i'm unsure of how handle dependencies stored in node_modules. copy of them well, or there more preferred way of doing it?

gulp.task('deliver', function() {   gulp.src('src/*.html').pipe(gulp.dest('deployment/'));   gulp.src('src/*.js').pipe(gulp.dest('deployment/'));   gulp.src('src/games/').pipe(gulp.dest('deployment/')); }); 

the standard way have package.json file lists dependencies. part of deployment process run npm install go through package.json , install necessary packages in node_modules folder.
