How to change host from localhost to my network ip in vue-storefront?

I have install Vue-storefront in my local machine(Ubuntu 18) by following these commands

git clone https://github.com/DivanteLtd/vue-storefront.git vue-storefront

cd vue-storefront

yarn

yarn installer

here I have used https://demo.vuestorefront.io as the backend
I have install vue-storefront successfully

in localhost:3000

but I want to change localhost to 192.168.0.172 and port 3000 to 8080

for this, I have made changes in vue-storefront/config/local.json

I have run

npm restart

How can I do this…
