Awesome and thanks for doing this! I would love Tunguska if it’s still available.
You can definitely scratch the sapphire. I took a mtb spill and got a tiny scratch on my 5x.
I quit Reddit cold turkey on the day the APIs died. Sync was synonymous to Reddit for me. When one died, so did the other.
There are JS barcode libraries out there, some better than others, some free, others paid. A few years back at a corporate job I built just the thing - a web app designed to replace a 3rd party mobile app. The back-end was Laravel + various AWS services, with a responsive front-end made with Tailwind.
The requirements were to make it mimic most of the mobile app’s functionality. There was also location tracking via browser APIs (to track the cargo at all times) and a barcode scanner. I used a paid library for that, and it was quite expensive, but very reliable. So it can definitely be done as a web app.
