Running 'npm run dev' with Valet ?

I am learning, Bare with me

Can i Use Valet organized domain instead of 'localhost:8080' ?

I made vuejs project using

$npm install -g vue-cli
$ vue init webpack my-project
$ cd my-project
$ npm install

Now i want to use laravel link instaed of npm run dev, but when i do and open i see blank page without any errors on my-project.dev
