How to send from node data to localStorage React?

node

const LocalStorage = require ('node-localstorage').LocalStorage;
localStorage = new LocalStorage('./localStorage');
localStorage.setItem('username', user.name);
localStorage.setItem('token', user.token)

react

const author = localStorage.getItem('username')
const token = localStorage.getItem('token')

In react console.log(localStorage) // {}

P.S: maybe need send from react to node GET request?

  fetch('/api', {
    method: 'GET'
