Vue official docs/tutorial are great. I also highly recommend Laracasts free Vue lessons:

* https://laracasts.com/series/learn-vue-2-step-by-step * https://laracasts.com/series/testing-vue

Awesome Vue has a good list of many vue resources: https://github.com/vuejs/awesome-vue

Initially, https://www.udemy.com/vuejs-2-the-complete-guide/ course helped me to get going. After that, I just read the official documentation and examples on Github.
