Deprecated packages

[oleteacher]

Instilling this wonderful project today and see:

npm warn config init.module Use `--init-module` instead.
npm warn deprecated [email protected]: Please upgrade to v9.0.0+ as we have fixed a public vulnerability with formidable dependency. Note that v9.0.0+ requires Node.js v14.18.0+. See https://github.com/ladjs/superagent/pull/1800 for insight. This project is supported and maintained by the team at Forward Email @ https://forwardemail.net
npm warn deprecated [email protected]: This module is not supported, and leaks memory. Do not use it. Check out lru-cache if you want a good and tested way to coalesce async requests by a key value, which is much more comprehensive and powerful.
npm warn deprecated [email protected]: Glob versions prior to v9 are no longer supported

On a production server, how worried should I be?

Are there ways to fix the deprecated packages?

Please forgive if silly questions, still learning Node.
