List of supported Node JS versions?

The trouble seems to be that there is no single source of truth for node engine version.
the ones that come to mind are:

  • package.json
  • .nvmrc
  • netlify env vars

suppose that all of these had some value. which would win?

I plan to remove all node version config, and add back only the one(s) needed.
In this instance…

  1. remove .nvmrc which had old node version: fail
  2. tried nvm expression in netlify env var >=12.13.0: fail
  3. revised netlify var 12.13.0

…and will later remove that netlify var to centralize configs.

3:03:05 PM: Attempting node version '>=12.13.0' from .nvmrc
3:03:06 PM: Version '>=12.13.0' not found - try `nvm ls-remote` to browse available versions.
3:03:06 PM: Failed to install node version '>=12.13.0'
