How to integrate laravel template with Vue.js

I have created my website in Laravel 5 with template integrated in it. Now I want to add chat feature in my website, so I decided to use Vue.js. The problem is that when I setup Vue.js in my project, the page template of that page in which vue.js is used is not working. I mean that all the css and js file of laravel getting mess up. Page looks horrible. How Can I use my existing template with Vue.js?
