Just finished a job search with Vue as the framework I have most experience in. Can confirm 95% of jobs seem to be React. Vue seems to be seen as a good option for moving away from sort of previous mess or something that backend/'full stack' devs can pick up quickly.
The senior jobs from my experience are there when the above goes awry without dedicated Vue (or even front end) knowledge.
I would guess that one of the benefits of knowing React is the the relatively easy transition to React Native, which allows you to deploy to mobile platforms as well. That's why React is so popular in the industry.
My main complaint is not with Vue itself, but with the lack of adoption as opposed to frameworks like React. I am having a hell of a time finding mid-to-senior level jobs - especially remote - working with Vue. When I do find them, it's usually some immature startup that doesn't provide basic benefits like medical coverage.
The Vue community needs to up their game on PR, so i'm very happy to see this documentary posted on HN! Kudos to the team for making such an amazing framework!
