Is running a NodeJS server is the background possible?

Hi,

I currently have a nodejs custom dota 2 game-state integration server that fetches live game data and serves it on websockets. Is there a way for me to include this in my app and have this run in the background?

I already have a game overlay for streaming made months prior that I want to have displayed in-game using overwolf, but the game data provided by overwolf does not match my needs.
