can i use it in 2021?

I want to use a fullstack template, so far I can't find a complete one, this looks a lot like it, but it's from 2019, I wanted to know if it can be used or due to time, are there new things to update manually?

Review the repository's current setup documentation against the compatibility question; the payload names no specific files or tests. Confirm whether the template remains usable and document any required manual updates, with a clear supported-version or date statement as the definition of done.
