Usage Example

api.js

import { put, select } from 'redux-saga/effects';
import { API } from 'redux-saga-rest';

import * as selectors from './selectors';
import * as actions from './actions';

const authMiddleware = () => function* (req, next) {

    // request middleware
    const user = yield select(selectors.user);
    const headers = req.headers || new Headers();
    headers.set('Authorization', `Bearer ${user.token}`);

    // retrieve the response
    const res = yield next(new Request(req, { headers }));

    // response middleware
    if (res.status === 401) {
        yield put(actions.logout());
    }

    // return the response
    return res;
};

export const auth = new API('/api/')
    .use(authMiddleware());
