Have you seen OpenUI5 by SAP? -> https://github.com/SAP/ui5-webcomponents

Look neat. They even have Typescript type definitions to it.

I did a simpile test with ScalablyTyped in order to import those into ScalaJS to no avail but there might be a fix.

The only implementation of OpenUI5 I've encountered as an end-user was "SAP Fiori" for managing expenses at a previous job.

It looks strictly OK if you just glance at it from a distance, but was incredibly buggy across every single browser that I threw at it, and SLOW AS HELL to boot. I'm talking UI elements taking a second or so to respond to actions that don't even interact with anything over the network.

I don't know how much of this is just down to the app itself being poorly designed and built, but just looking at the UI5 components was enough to make me recoil in disgust.

You just made me conscious on my initial choice for an invoices ingest app, so I might end up looking somewhere else: you are totally right, it takes ages to load a moderatively simple layout, not even taking into account a single XHR request.

The playground is not that bad: https://sap.github.io/ui5-webcomponents/playground/component... (for instance). But as other commenter pointed out, just take a look how long it takes to load some badges.
