CRXJS w/ Sandbox Page That Loads Remote React Script -- Best Practice?

[Jgordon-pencilwrench]

Asking for best practices here:

The Goal:

I want to avoid going through the review process when I make changes to my extension, so I've decided to explore using a sandboxed page that loads a react app from my CDN.

The Implementation Plan

The user will interact with the page, then the sandboxed page will post a message for my extension to handle. I think it will work, but I'm looking for suggestions on how to handle developing this app.

The Issues I see:

1. CRXJS doesn't look like it works with sandboxed pages for local development. I'd need to create a second page that isn't sandboxed to use during development
2. I probably have to develop two projects: one for the extension, one for the sandboxed code.
3. SOLVED : It's a react-vite app I'll be loading. I'm wondering if I'll run into issues with hashing the scripts and css files (though I could turn off hashing in my vite config at the risk of caching stale code). -- Set the cache expiration in the headers to expire at x time.

Have other folks done this before (I'm assuming yesssss)? What is the ideal development flow for this kind of thing? I'm pretty sure this would pass Google's review, but would love to hear other people's experience.
