A boilerplate using Gulp, SASS with concatenation and minification process for both development and deployment. It's also the skeleton we use for our projects in

Get started!

We assume that you have nodejs (and therefore npm) installed in your computer, be it Linux, Mac, or Windows.

  1. Clone this repo from
  2. Run npm install from the root directory of the cloned repo (where this is located). This will install all the dependencies (Gulp, SASS, etc...)
  3. Run gulp dev (may require installing Gulp globally: npm install gulp -g)
  4. All the contents in the folder app will be processed in development mode and will output in the deploy folder, so you can access your project there in the browser. No minification occurs with gulp dev.
  5. Run gulp deploy to achieve the same as in #3, but with minification both for CSS and JS.

Any changes you make in the app folder during the #3 gulp dev process will be watched and automatically injected into deploy folder. You have to reload your browser manually (F5) to see the changes as for now there is not live-reload.

Directory Tree

Basic explanation of important files and folders in this skeleton:

/app                       (your development folder)
   /images                 (all the images there and in the /images subfolders will be compressed when deployed)
      /vendors             (third party javascript libraries)
         /autoinclude      (the files placed here will be automatically included -in no special order, but before "/development" folder-)
         jquery.js         (if you place the files outside /autoinclude folder, you can define its executing order in /gulp/config.js)
      /development         (your javascript)
         /autoinclude      (the files placed here -such as your own classes- will be automatically included -in no special order, but before "main.js" file)
         main.js           (your main javascript file | it is the last .js included/executed)
      /vendors             (third party CSS, SASS, such as bootstrap)
         /autoinclude      (the files placed here will be automatically included -in no special order, but before "/development" folder-)
      /development         (your SASS, CSS)
         _clearfix.scss    (clearfix fix. it's included by main.scss on the top of the file)
         _reset.scss       (reset fix. it's included by main.scss on the top of the file)
         _vars.scss        (variable file. just if you need it.)
         main.scss         (your main style file, you can include other files in there using @import | it is the last scss executed.)
   index.php               (file where the CSS/JS files are injected to | you can create as many .php, .html, etc. as you wish, but you have to include the injection comments inside in order to get the CSS/JS injected.)
/deploy                    (folder where the compiled project will be deployed)
/gulp                      (the Gulp folder, where the Gulp configuration and scripts are located)
package.json               (npm dependencies of this skeleton)

How to include third party JS libraries (jQuery, hammer.js, etc.)

There are two ways to include third party javascript libraries.

  1. Include the files inside folder /app/js/vendors/autoinclude/. They will automatically be included before any other file. But use it only for files/libraries where the inclusion order doesn't matter, as you can't controll the order this way (they are included alphabetically), so, if for example, you include in this folder aCoolPluginThatRequiresjQuery.js and jquery.js - the plugin won't work as it is included before jQuery. So in order to avoid a file-name-changing-to-include HELL, we are going to use the #2 way of including JS files and dependencies.
  2. Include the files inside folder /app/js/vendors/. You need to define the order of the inclusion in /gulp/config.js, for example:
// config.js file
'use strict';

module.exports = {
  // -- some other config here -- 
  'scripts': {
    'srcfolder': 'app/js',
    'src' : [
              'vendors/jquery.js',           (this is the first included file, in this case, we included jquery)
                                             (you can include more files here, and the order will be respected)
              'vendors/autoinclude/*',       (..then the /vendors/autoinclude/ folder is included)
              'development/autoinclude/*',   (... self explanatory...)
              'development/main.js'          (... and finally your script file, you can also include more lines with more scripts.)
    'dest': 'deploy/js'
  // -- some other config here -- 

How to include my own javascript code? do I have to put everything in main.js?

No, you don't. You can put your JS classes inside /app/js/development/autoinclude/ and they will be automatically included and injected into your html/php/whatever files, then you can use main.js for the main JS code of the App. The same as in the previous section applies regarding order of inclusion, so please read it carefully.

How to include third party CSS/SASS?

It's very similar to how you include JS (check the previous sections), but with a main difference; There is not a /app/styles/development/autoinclude/ folder. Because we take Sass as a base for developing, you should include your own development files using @import so the Sass preprocessor will have a reference to the functions you are using there. Otherwise it won't get the references and will throw an error to the console. There is a /app/styles/vendor/autoinclude/ folder though, so you can include Bootstrap or any other third app libraries or dependencies of plugins for your website there. Note that all the files included via @import should start with a underscore, like _something.scss, this way they will be ignored by Gulp and will not be included twice. We recommend main.scss to be the only file without underscore in /app/styles/.


Question: Why are some images not showing in the website? Answer: It's probably due to one of this reasons:

  1. Your image path in your CSS is wrong. Bear in mind that when compiled, the path of your images in CSS relative to your .php/.html will be ../images/yourimage.png
  2. You added the images in /app/images/ while executing gulp dev. The /app/images/ folder is not watched, so everytime you add an image to it, you should re-execute gulp dev or gulp deploy so the images will be copied to /deploy/images/.

Question: Why am I not seeing the CSS changes when I reload my browser? Answer: Your SASS or JS probably has a syntax error and Gulp closed. Check CMD console, fix the syntax error, and re-execute gulp dev or gulp deploy.

To do

  1. Add live-reload, browser sync
  2. Minify html code
  3. ...
