This is a simple URL shortener made for learning the basics of Flask and Vue.
It uses PostgreSQL as the database and Flask-SQLAlchemy. It has a
very simple database model: a single table with a primary key, a URL, a short
token and an optional expiration date.
I was especially interested in learning how to test the server.
The front-end was made with vue and is not very involved.
I used to host it on Heroku but decided to not do it anymore since these applications can be exploited.
