This is my call_api.js

import request from 'superagent';
import base from '../base';
import getToken from '../../utils/getToken';

export default (id) => {
    const token = getToken();
    return base(
        request
            .put(`/api/client/workspace/${id}/leave`)
            .set('Authorization', `Bearer ${token}`)
    );
};

This is my base.js

import pathOr from 'ramda/src/pathOr';

export default function base (request) {
    return new Promise((resolve, reject) => {
        request
            .end((err, res) => {
                if (err) {
                    return reject(pathOr({}, ['response', 'body'], err));
                }

                resolve(res.body || res.text);
            });
    });
}

How to change base.js so that all call to request (put/get/post etc.) will have the host appended with yoyo.com, in this case the put will be to yoyo.com/api/client/workspace/${id}/leave rather than /api/client/workspace/${id}/leave?
