Exercise work for Fullstackopen 2021 MOOC course.
On the barebone, the back-end uses Node.js with Express and Apollo server. For data storage the back-end uses MongoDB that is implemented with the help of Typegoose. As for testing, I created a separate collection in the MongoDB that was used specifically for testing purposes. Testing was done with the help of Jest library. For more information about this project you can contact me or check out the main (front-end) repository.
Link to the front-end can be found here.
