Probably want to stick to 4.2.1 GPL [1] (there are GPL versions on 5.x and 6.x but only minor point releases)

I think it's great for enterprise form-fill-in applications. It's a complete widget set for doing in the browser what GUI apps from 20 years ago had in Java (for example)

I have no interest whatsoever in writing web applications by using multiple components from multiple sources. I want to use a single toolkit. ExtJS satisfies my requirements. The tooling is awkward, but I've learned how to use it.

examples

"web desktop" https://docs.sencha.com/extjs/4.2.1/extjs-build/examples/des...

widget library (classic) https://docs.sencha.com/extjs/4.2.1/extjs-build/examples/bui...

Please shout (email in profile) if you need any help. Good luck!

My project is a frontend for a CRUD app which a huge database. I will definitely ask for help when I am at my wits end! Thank you !

My biggest gripe is that ExtJS doesn't html encode the replacements in the component templates. This is something that react got right from the start.
