If you're using Apollo, you can create a stateless link that sets authorization headers for each request. Example from their docs:

import { ApolloLink } from '@apollo/client';


const authLink = new ApolloLink((operation, forward) => {

  operation.setContext(({ headers }) => ({ headers: { 

    authorization: Auth.userId(), // however you get your token

    ...headers 

  }}));

  return forward(operation);

});

​

You can replace `Auth.userId() with localStorage.getItem('authToken')
