How to use compile ES6 (react) components and foundation sass with npm start

I followed this tutorial to setup a react project and I thought I nailed it. After installing everything works as it should.

But I have to create a website that uses foundation as a front-end lib. The tutorial I linked above runs server.js when I run npm start but foundation-cli uses the same command for compiling all foundation sass code to css.

At the moment when I run npm start it only runs react and not foundation. How can I run foundation too? can I make it so that it'll automatically run both?
