Deployment to Heroku

[FredLavoie]

Many students have had issues deploying to Heroku recently (myself included). Navigating to /api/days for example times out.

In the package.json file, the following should be added to fix this issue:

  "engines": {
    "node": "12.20.1"
  },

I found the solution from this thread:
