That sounds false to me. When was this era and what exactly did it look like? React has been dominant for around a decade, but Angular and Vue still see wide usage and Svelte is somewhat on the rise. (Although retention/interest in Angular has been going down.)[1]

I'm judging by what I see teams choosing for new projects—both dev shops and corporate/internal devs. Even 5 years ago they might have debated Vue vs React, but there's not even a discussion anymore.
Sure, but how many teams are you observing? My company is split between Vue and React for different projects, and while greenfield new ones are getting React, Vue is not being deprecated here.
I'm building the front ends for a few projects in Vue right now, it's quite pleasant!
It's easy to work with, there's nice router and internationalization packages, ready made components with PrimeVue (though PrimeReact and PrimeNG are nice too; as well as other component libraries), PrimeFlex and Pinia for state management is wonderfully simple and scales pretty far. There's devtools for most browsers, the toolchain isn't super complex and while the ecosystem could be bigger, it's not inadequate either.
