Mounting a new tree

The tree below represents a React application mounting. During mount, two components read from an external, mutable source. The first one (List) reads version 1 of that data and the second one (Item) reads version 2.

                Stop using JWTs
              
          
    Stop using JWTs!

TLDR: JWTs should not be used for keeping your user logged in. They are not designed for this purpose, they are not secure, and there is a much better tool which is designed for it: regular cookie sessions.
If you've got a bit of time to watch a presentation on it, I highly recommend this talk: https://www.youtube.com/watch?v=pYeekwv3vC4 (Note that other topics are largely skimmed over, such as CSRF protection. You should learn about other topics from other sources. Also note that "valid" usecases for JWTs at the end of the video can also be easily handled by other, better, and more secure tools. Specifically, PASETO.)
A related topic: Don't use localStorage (or sessionStorage) for authentication credentials, including JWT tokens: https://www.rdegges.com/2018/please-stop-using-local-storage/
The reason to avoid JWTs comes down to a couple different points:

The JWT specification is specifically designed only for very short-live tokens (~5 minute or less). Sessions

    I bundled these up into groups and wrote some thoughts about why I ask them!
If these helped you, I'd love to hear about it!! I'm on twitter @vcarl_ or send me an email carl.vitullo@gmail.com

How long will it take to deploy my first change? To become productive? To understand the codebase?
What kind of equipment will I be provided? Will the company pay/reimburse me if I want something specific?
