Create Heroku App.json after manual deploy and configuration of App

I have successfully deployed my app on Heroku, added add-ons, updated env var via the control-panel settings, etc. I am now looking at creating an app.json after the fact. Is it possible to query Heroku in some way to have an app.json generated from the hosted application that I've created?

Solution

  • I found the answer via another SO post: Heroku provides an App.json-creation tool. Simply log into Heroku, navigate to your app and add "/app-json" to the end.

    For example:

    https://dashboard.heroku.com/apps/your-app-name/app-json
