Hey @dashbarkhuss
Easiest way to figure out what version of node/npm is used to build a site is looking at a deploy log. In the deploy log you’ll see lines (towards the beginning) like
12:38:04 PM: v16.14.0 is already installed.
12:38:04 PM: Now using node v16.14.0 (npm v8.3.1)
You can specify build environment variables such as NODE_VERSION and NPM_VERSION.
