I haven't had a chance to look at Vue in depth but it seems to me that its useful for building apps where you don't need a build tool which makes sense to me.
The main thing I don't get is why use Vue over React if you're going to use single file components with some kind of build tool?
I'll paste my comment from another post in this thread:
>> I hear a lot that "Vue is easy to learn"...
> That's why I started working with Vue. It seemed easier to approach for someone coming from a server-side language perspective (I'd mostly worked with Python/Flask and PHP/Symfony before). I could slowly ease into using pieces of it until I learned enough to write a whole project in Vue. You can probably do the same thing in React, but the Vue docs were written to address my use case.
Someone will inevitably say you can use JSX in Vue but if you do that I don’t see the point in picking Vue.
