[RESTfull API Project Feedback Review] -> URL Shortener Microservice

Finally finished the RESTfull API URL Shortener Microservice Project, a lot of fun!

Take a look and tell me what you think (constructive opinions, bugs, suggestions, etc…)
I’ve made a client side to ease the use of the app.
Just don’t spam the server, please…
