📙 About


Notifications Service is a simple microservice application developed for reinforcement of some concepts such as repository pattern, in memory database and prisma basics.  It includes unit testing for most of the content created.

On this project development, the intention was to provide a very organized and well structured app architecture despite of its simplicity.
