Contributing to the web repository requires both front- and back-end sklls. This document describes how to contribute to and describes all the technical stuff you will need to know. If you want to contribute, the first thing you will need to do is installing the source code on your local environment.


The installation can be found on the generic installation page, describing the complete set of instructions.


As you've probably seen in the installation summary we are hosting our repositories on github. As any larger project we are also using a versioning strategy; an easy one :) we don't want to get the things complicated. The version strategy is based on this branching model.

The model includes:

  • master branch,
  • develop branch and
  • hotfixes

The idea is that the master branch always contains a stable release and development happens on the develop branch. When we plan to create a new release we merge the develop branch to the master branch and create a new release. If bugs are introduced in the master branch (stable release), hotfixes are pushed to the master branch and merged back to the develop branch. Believe me, it's very straight-forward if you are into it.

Dependency management

The web is created with PHP and JS. It's obvious that we don't have developed all the functionality ourself, a lot of other open-source third-party libraries are used. To install these libraries (dependencies) a dependency manager is used. For the PHP side we have composer and for the JS side there is bower.

Composer (PHP)

Composer is a dependency manager for PHP, which is very easy to install and use. To install composer execute following commands:

php -r "readfile('');" > composer-setup.php
php -r "if (hash('SHA384', file_get_contents('composer-setup.php')) === '41e71d86b40f28e771d4bb662b997f79625196afcca95a5abf44391188c695c6c1456e16154c75a211d238cc3bc5cb47') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"
php composer-setup.php
php -r "unlink('composer-setup.php');"

After composer is installed properly you can just do composer install or composer update within the root directory of the web repository; this will update all the dependencies if a newer version is available.

composer update

Bower (JS)

Bower is a dependency manager for JS, it's very similar to composer. To install bower you'll need to download nodejs and execute following command:

npm -g install bower

After bower is installed you can install or update dependencies within the /public directory.

bower update


The web is created with two frameworks and a lot of third-party libraries.

Laravel 5.4

Laravel is a very powerful and popular PHP framework. This is also the main reason why the web is created with Laravel, the community is huge. A lot of people are writing tutorials and recording webcasts. This makes getting started with contributing to the web repository so easy. You will find all the information you need on the Laravel documentation site.


BackboneJS is a lightweight framework. It's used in the web to create the dynamic behaviour and structure the source code. You will find all the information you need on the BackeboneJS documentation site.
