Check if API is running within Heroku?

How do I check within my Node / Express app if it is running within Heroku?

My understanding is that .env files don't work in Heroku. So this line will crash the app in Heroku. So, I want to prevent running this within a Heroku environment. 

const dotenv = require('dotenv');
dotenv.config();

One way you can do it is to create an environment variable called IS_HEROKU. On Heroku that's done in the app's dashboard, in the Settings tab, under Config Variables. Add IS_HEROKU: true. You can also use the CLI:

heroku config:set IS_HEROKU=true

It's described here.

You will now have access to it with process.env.IS_HEROKU. The value is a string.

I feel is simpler to use environment variables this way compared to using dotenv. If it was my project I would specify all the environment variables this way.
