Our team was made up of two React Developers - Tomasz and Patryk. They developed Front-End structure of the application using React.
Apps in React are created of reusable components. The biggest advantage of this framework is the huge community. Developers provide their own open source solutions, that other devs can use in their projects.
On the server side, we used NodeJS with MongoDB. Furthermore, we used Mongoose, that is Object Data Modeling library which is designed to work in an asynchronous environment. During works on server side, we were using Buddy.Works - easy to manage CI/CD (continuous integration and continuous delivery) product, for constantly testing and deploying every change that we made.
