I've created this project as programming excercise. I wanted to practice usage of Factory Method pattern in React world.
The idea is to show list of recent changes made on Wikipedia in Real Time. Wikipedia provides messages stream with type (edit, new, categorize, log). Every type can have different data and we might want to add different behaviour for them (like onNotificationClick, onUserClick etc). NotificationsFactory is used to achive the above, via creation of Notification components, based on type.
Messages are sent from Wikipedia in one-way stream, called Server-sent event. It operates on HTTP and use EventSource in the browser for receiving data.
