Vue.js 2 page and element transitions with vue-router
I'm not sure if it solves all your problems, especially since I don't know exactly what behaviour you are looking for, but the transition effects in Vue provide transition modes.
transition mode="out-in" is perhaps what you are looking for. It waits for the first transition to end before starting the new one and is useful when transitioning between components. Check out the docs, they're very thorough and really good.
