Should EUI consider moving to a different package manager from Yarn Classic?

[cee-chen]

With the advent of Yarn v2/3 (Berry), EUI now requires Yarn v1 (Classic) specifically as a package/dependency manager. Upgrading would be a fairly large technical debt item, and something that should be investigated before Yarn Classic reaches end of life support:

• https://yarnpkg.com/getting-started/migration

However, it may be worth considering other package managers as well since the migration level of effort be approximately equivalent. pnpm is a package manager that has also gained popularity recently. It may be worth keeping in mind as well that ESM is what JS is steadily moving towards, and looking for a manager that embraces that architecture.

We'd be super interested in hearing from other developers what package manager you use and why - please leave us a comment! This discussion is not intended to create a final decision or action item, it's simply meant as an opportunity for devs to share their thoughts and for information gathering.
