cordova command. But Cordova platforms, plugins and other packages also contain code that is executed by Node.js.
As such, we have some rules and guidelines about Cordova's Node.js usage:
Cordova CLI, the tooling behind it and Cordova platforms all include scripts that are directly run by Node.js on the developer's machine. As such, we try to make sure those work on the indicate Node.js versions and test these scripts on a senseful collection of Node.js versions (latest supported, major versions, newest).
When a Node.js version is dropped from this support and testing roster, this manifests a major breaking change of said package.
A special case is
cordova-paramedic, which is used by all core plugins to run plugin tests. While we control the Node.js version of that and thus could prefer newer Node.js versions, Paramedic can be used by any plugin author to test their plugins as well - and as such has to be tested across multiple Node.js versions and should not drop support for older Node.js versions.
