LGTM!

I have one question: Is it convenient to add Node 21 to the matrix?

LGTM!

Typically, projects test only against LTS versions. Node 21 has a "short lifespan" (temptatively, EOL April 2024), for this reason most of the developers avoid using this intermediate versions in production.

So, IMHO, I wouldn't add it, given that Node 22 (LTS) will be out in few months.

I have a doubt here, we should point our local dev stack to node 18x at least? we couldn't find unexpected catches in ci if we don't do this?
