GameStore

Technology stack used to implement the project are:

The game store is a platform, where the users can buy games.

The system contains information about users and games.
Users can register in the system. After successful registration, the user has email, password, full name, list of games and information whether he/she is an administrator or not.
The first registered user becomes also an administrator. You can manually mark users as admins in the database.
A game has title, trailer (YouTube Video Id), image thumbnail (URL), size, price, description and release date
Users can buy games and make orders. Each order has a single buyer (user) and one or many products.

All users can view all games.
All users can view details of each game.
Logged-in users can logout.
Logged in users can add/remove games from their shopping cart.
Logged in users can buy games that are added to the shopping cart and those games are added to the profile of the user and cannot be bought for second time.
Administrators can add, edit or delete games.
Basic user can not add, edit or delete game.

The guest users can register and log in.

o Size – must be a positive number with precision up to 1 digit after the floating point.

o Trailer – only videos from YouTube are allowed. Only their ID, which is a string of exactly 11 characters, should be saved to the database. For example, if the URL to the trailer is https://www.youtube.com/watch?v=edYCtaNueQY, the required part that must be saved into the database is edYCtaNueQY. That would be always the last 11 characters from the provided URL.
