To authenticate to the Google Maps/Places API, you'll need your own API key. To run locally, create a .env based on .env.sample and put in your own key. Uncomment require('dotenv').config() in index.js. To run on Heroku, set your API key as a config var and keep require('dotenv').config() in index.js commented out. You will not need the .env to run on Heroku.
