Initially Skeptical, but coming around

I'm an integration engineer. Our current problem is more internal, we're trying to hire for our Acumatica team. Our biggest issue is lack of available / personable / modern engineers, to which we're excited about the introduction to the javascript ecosystem. JS engineers are objectively easier to hire for. That being said, it was a terrible decision on Acumatica's part to use Aurelia.js. Use a defacto standard like React or Angular. Aurelia literally says in their banner "Join thousands creating next-gen apps" while there are literally millions of engineers using react and angular. Whoever picked Aurelia likely thought deno.js would be the next big thing as well (spoiler alert, it wasn't - TypeScript became a thing.)

It's familiar to our internal team, so there is very little downtime when bringing in a new person to be trained, but occasionally buttons or labels disappear, and we get tickets requesting we add back some now deprecated functionality. The documentation is garbage, the DAC browser is ok, but leaves a lot to be desired. The videos are for sales / non-technical users to set up no-code solutions, and they're great at that, but there is little serious documentation or example code outside of a few tutorials for developers.

We use it as ERP for industrial agriculture and equipment. We do mostly b2b but because we're already in the ecosystem we're expanding to physical retail and POS. We'll see how it goes.
