Using gulp at MakeUseOf

At MakeUseOf, since the start of the new theme, we simply wrote plain 'ol CSS and normal JS. No cool stuff like concatenation of compression or minification. Plain code, edited and uploaded through Filezilla.

Now we've moved on to a better workflow - Using gulp, Vagrant, git & Github. Here I'll talk about how we set up and use gulp.

Setting up gulp

Setting up gulp was surprisingly extremely easy. I just ran these two commands:

$ npm init
$ npm install gulp -g
$ npm install gulp --save-dev

And gulp was ready to go. To avoid syncing useless stuff, I added node_modules to .gitignore (And James reminded me to add .sass-cache as well).

The Gulpfile

We have two main requirements for scripts and styles currently:

  • Processing, minifying, and prefixing SASS and Compass.
  • Minifying and using includes on JS.

Multiple plugins are used to achieve this:

I've set up three tasks for gulp (including the watch task).

Loading Plugins

As you can see above, I'm using gulp-load-plugins here. This adds a global object that has all the plugins, and so I don't need to manually add each plugin on install.

var gulp = require("gulp");  
var p = require("gulp-load-plugins")();  

Plugins can then be accessed through p.pluginName(), like, p.minifyCss().


MakeUseOf is a large site and gulp's installed in the wp-content folder. Managing paths can get ugly, easily, hence I've made an object, paths, which has file paths to all used locations.

Javascript resides in js/src and js/src/plugins folders, which is compiled to js, and SCSS is in styles folder, which is compiled to style.css (Since we use WordPress).

var paths = {  
  m2014: {
    scripts: {
      src: 'themes/makeuseof2014/js/src/*.js',
      dest: 'themes/makeuseof2014/js'
    styles: {
      src: 'themes/makeuseof2014/styles/*.scss',
      dest: 'themes/makeuseof2014'
var m2014 = paths.m2014;  

m2014 here refers to the theme name, so the script can easily be modified for other themes as needed.


The styles task is responsible for doing three things:

  • Converting SASS to CSS.
  • Prefixing CSS.
  • Minifying CSS.

It's a pretty straight-forward task

gulp.task('styles', function() {

  var src = m2014.styles.src;
  var dest = m2014.styles.dest

  // Compiles sass, autoprefixes, and compiles files
  gulp.src( src )
  .pipe( p.compass({
    css: 'themes/makeuseof2014',
    sass: 'themes/makeuseof2014/styles',
    style: 'compressed',
    comments: 'false'
  }) )
  .pipe( p.autoprefixer() )
  .pipe( p.minifyCss() )
  .pipe( gulp.dest( dest ) )

The src and dest variables are set so that I can easily use either in the main function.

gulp works through piping files (Can be in an array, can use the wildcard, etc) through a series of plugins. Each plugin can have specific settings with it, passed as arguments. If you're familiar with jQuery, gulp should be pretty easy to understand and write.


Our goal with scripts was simply - Compressing them, and allowing use of includes.

gulp.task('scripts', function() {

  var src = m2014.scripts.src;
  var dest = m2014.scripts.dest

  gulp.src( dest + '*.js', { read: false } ).pipe( p.clean() );
  // Clean old files

  // Uglifies files from src folder -> main folder
  gulp.src( src )
  .pipe( p.include() ) // JS Includes
  .pipe( p.uglify() ) // Compresses JS
  .pipe( gulp.dest( dest ) );

Here's how the scripts task looked.

Note the 'clean' thing - It deletes all compressed JS files from the js folder. dest + *.js deletes only the Javascript files in js folder, not in it's subfolders. (Learnt this the hard way…)

Done using gulp-clean, This is important because we might delete source scripts some times, and in that case, the compiled script will still remain in the js folder.

Setting read to false will prevent node from reading the files, and will decrease time taken.


The watch tasks calls the above tasks whenever there's a change in the files in the styles folder or in the js/src folders.

gulp.task('watch', function() {, ['scripts']);[m2014.styles.src, m2014.styles.dest + '/**/*.scss'], ['styles']);

m2014.styles.dest + '/**/*.scss' checks for scss files in subfolders of style, otherwise it won't run if a file in one of the subfolders was edited.

The default task

gulp.task('default', function() {  
  gulp.start('scripts', 'styles', 'watch');

Just runs the three tasks that we defined above.

Syncing files

At MakeUseOf we use a Vagrant set up and a git repo set up at the wp-content folder.

Gulp-related files that are synced are package.json and gulpfile.js. Others are added to .gitignore, and can be installed on each computer seperately (Through npm install, basically).
