It really depends on what you're missing from ExtJS. Yes, there are some frameworks oriented towards more desktop-like UI components. Some of them even do layout, maybe even non-view stuff (Kendo seems to do at least the former).
But there are other degrees of ExtJS nostalgia:
- Being allowed to do everything in a desktop-like manner, and not having to bother too much with either mobile or more stylized web applications, even in enterprise contexts. No technical issue, no technical solution.
- Doing that in a simple manner. Even contemporary (> v4 or even v3) ExtJS might not be "ExtJS" in this regard, as the framework part got a lot more complex. First with their own weird tooling, nowadays with the worst of both worlds.
- Not having to touch HTML and CSS. Early ExtJS allowed you to do most things with heavily nested JS literal objects. With angular/react/etc. it's all separate syntaxes, most of them with angle brackets.
I'm also a bit pissed that in the past 10 (or more) years we still haven't gotten good established components in the browser that do even half of what ExtJS could do (and still does).
