Cashless payment system

Cashless payment system thumbnail
A company I worked for had a coffee machine for which employees could purchase coffee. However, the payment was done by putting coins in a jar. Not only did this present the obvious risk of theft, this system was also impractical for people not carrying spare change at all time. I decided to solve this issue by designing this cashless payment system.

Express authorization middleware

Many applications require some form of authorization mechanism to prevent users from accessing restricted content. Authenticated users are commonly in possession of a cookie containing identification data. With the authentication microservice that I designed, this cookie contains a JWT that contains the user's username. This JWT is sent in the authorization header of HTTP requests. Thus, authorization can be performed easily within each application by simply decoding the JWT. To do so, I designed this simple middleware for ExpressJS.
