Set your NodeJS version in Netlify

A couple of times I needed to fix the NodeJS version on a Netlify site, I found myself googling it a couple of times, so this little how-to is basically a note-to-self.

The solution to setting a fixed NodeJS version is actually quite easy:

1. go to your desired website
2. go to Site Settings
3. under Build & deploy
4. scroll down to Environment
5. add a new environment variable named NODE_VERSION
6. set it to your desired version (major or minor)

When you set it to 16, it will automatically use the latest 16.xx.xx.
