It’s called Biu, because in Chinese this Pinyin (something like phonetic symbols) pronounces like “be-yo”, the sound that old-fashioned laser gun would make in films.
I decide not to use database but instead use a single text file, because for a private URL shorter, the links number would hardly be big. And it will read all the links into memory once starts.
Considering its application scene, I think it’s rational to make things, including setup, simpler.
