When I attempted to install the databsae-refactor version of the website on ubuntu (4.4.0-98-generic #121-Ubuntu SMP), I had a warning when I went to install Bower saying:
npm WARN deprecated bower@1.8.2: …psst! Your project can stop working at any moment because its dependencies can change. Prevent this by migrating to Yarn: https://bower.io/blog/2017/how-to-migrate-away-from-bower/
