\chapter{Used Technologies}
\label{chap:technologies}

The technologies used in the project change quite quickly in order to meet new requirements,
especially on the frontend, where the tools and best practices are evolving rapidly.
The following tables show the overview of technologies used in the project in spring 2018.

%When this project started in 2015,
%we used several at that time popular technologies
%(AngularJS, Bootstrap, bower, grunt)
%which became obsolete during next 2 years,
%so we replaced them by newer ones.
%Many technologies were introduced naturally as the projects grew,
%e.g. Django Rest Framework for REST API,
%or redux-saga for cleaner handling of asynchronous side-effects
%(instead of the originally used redux-thunk).
