Hey, can i be assigned this issue?
Also, must the app be developed alongside a HTTP-server or would a plain hello-world-go program be sufficient.

Hello @bhaaaav are you still working on this?

[bhaaaav]

Heyy @sarah-kamall yes. I just need to make a PR.

Is it safe to say now that no one is working on it? @bhaaaav @razvand
