What are officially supported node versions?

I updated the email template stack to support Node v16 and many packages to the latest versions. While testing, I noticed it works fine with Node v14, v16 and v18, but I couldn't compile the project with Node v10. So, I started from scratch to find which package caused this problem because I did not want to submit a PR that would create a breaking change.

I was surprised to discover that I couldn't compile the fresh cloned project from the official repository with Node v10, even though it is clearly written in the Getting Started section:

"To use the stack, you'll need Node.js no greater than version 10 installed on your machine."

I am getting errors with Node v10 on all my machines (two Macs and one Linux). I also tried at least 3 different versions of Node (10.24.1, 10.22.1, 10.13.0).

Cloning and installing Node modules goes fine:

❯ git clone https://github.com/foundation/foundation-emails-template test
...

❯ cd test
...

❯ nvm use v10
Now using node v10.24.1 (npm v6.14.12)

❯ npm install
...

But I am getting the error as soon as try to run it

❯ npm start
...

var self = dartNodeIsActuallyNode ? Object.create(globalThis) : globalThis;
                                                  ^

I kindly ask @joeworkman to state which node versions are officially supported.

EDIT 2: I intentionally separated the pull request for new node version support https://github.com/foundation/foundation-emails-template/pull/71 from the one that restores the node 10 support. If only v12+ should be supported, everything is in this pull request. If v10 should be supported, too, then https://github.com/foundation/foundation-emails-template/pull/70 should be merged too

I also tried to use a fresh install of foundation-cli (which is deprecated as far as I know), hoping it would give me a working version, which I could use as a starting point for my update didn't work either.

Installation works

❯ npm install foundation-cli --global

But as soon as I try to create a project, I get the error:

❯ foundation new --framework emails
/Users/viking/.nvm/versions/node/v10.24.1/lib/node_modules/foundation-cli/node_modules/string-kit/lib/unicode.js:237
        return emojiWidthLookup.get( code ) ?? 2 ;

Since this is deprecated and doesn't work, it should probably be removed from the documentation.

EDIT: I just tested foundation-cli with Node v12 and v14. With v12, it throws the same error as with v10. With v14 it partially works. You can create a project, but you must run yarn or npm install to install the required Node modules.

I really need to know what are officially supported node versions, so I can make a proper PR request, which will solve all those issues: https://github.com/foundation/foundation-emails/issues/1113 https://github.com/foundation/foundation-emails/issues/1120 https://github.com/foundation/foundation-emails/issues/1124 https://github.com/foundation/foundation-emails/issues/1127 https://github.com/foundation/foundation-emails/issues/1129

Important note: You can use the official repo with Node v14.
