Heroku Procfile with web process type

I am deploying a create-react-app which uses an Express server to do some server-side rendering.

I am using the cra buildpack: https://github.com/mars/create-react-app-buildpack and a Procfile with a web process type.

I'm not sure exactly when web processes are run. Is the Procfile just executed once when deployed?

By default, Heroku runs one Dyno for the web process, and it receives inbound HTTP traffic. This will happen soon after your first deployment. You can choose to scale up/down the number of dynos for each process type if required, including not running a web process at all.

Here's a link to a heroku article that explains this: https://devcenter.heroku.com/articles/procfile

Excerpt:

The web process type is special as it’s the only process type that will receive HTTP traffic from Heroku’s routers. Other process types can be named arbitrarily.
