First start the app

yarn start

In your consuming app add the following before you init the shippo sdk. Shippo doesn't expose the endpoint as an option so we have to mutate the constructor static values.

import Shippo from 'shippo';

Shippo.DEFAULT_HOST = 'localhost';
Shippo.DEFAULT_PROTOCOL = 'http';
Shippo.DEFAULT_PORT = '8080';

If you find a new mock response that is relevant, please add it to the collection in src/shipment/responses so we can share Shippo tribulations across the team.
