Localhost:3000 Version Displayed Differently from Heroku Deployed Version - Node.js

I've deployed my directory to Heroku using git push heroku master, but nothing happens.... Everything up-to-date is what the screen reads.

How can I push to Heroku the exact version that I am running locally, since the local version does the things I want?
