react-redux-fetch/lib/middleware/fetchRequest.js.flow

A declarative and customizable way to fetch data for React components and manage that data in the Redux state

import container from '../container';
import onFulfillment from '../utils/onFulfillment';
import onRejection from '../utils/onRejection';

const fetchRequest = (store, next, action) => {
  const req = container.getDefinition('requestBuilder').getArgument('build')(action.request.url, {
    method: action.method,
    body: action.request.body,
    headers: action.request.headers,
  });
  const meta = action.request.meta || {};

  return fetch(req).then((response) => {
    meta.response = response;
    return response;
  }).then(container.getUtil('handleResponse')).then(
    onFulfillment(store, next, action, meta),
    onRejection(store, next, action, meta),
  );
};

export default fetchRequest;
