redux-threads v0.2.0

redux-threads

Helpers for reusable combinations of selectors, actions and reducers in redux.

Installation

npm install redux-threads

Usage

makeConnectArgs

A "thread" is an array of the form: selectors, action creators, prop mergers function.

makeConnectArgs takes any number of threads as args, and returns an array that can then be spread as args into react-redux connect

import { connect } from 'react-redux';
import { makeConnectArgs } from 'redux-threads';

// selectors & action creators imported here
// component to connect imported here

const thread1 = [
  {
    selector1,
    selector2,
  },
  {
    actionCreator1,
    actionCreator2,
  },
  (stateProps, dispatchProps) => ({
    compositeProp: dispatchProps.actionCreator1.bind(
      null,
      stateProps.selector1,
    ),
  }),
];

const thread2 = [
  {
    selector3,
    selector4,
  },
  {
    actionCreator3,
    actionCreator4,
  },
  // prop merger function is not required
];

const connectArgs = makeConnectArgs(thread1, thread2);

export default connect(...connectArgs)(ComponentToBeConnected);

This is useful for passing collections of selectors and action creators into multiple connected components.

createConstants

Given an array of constant strings, returns an object where keys equal values for the string and async suffixed variants (_START, _COMPLETED, _FAILED).

import { createConstants } from 'redux-threads';

export default createConstants([
  'AN_ACTION_TYPE',
]);

/* default export is:

{
  AN_ACTION_TYPE: 'AN_ACTION_TYPE',
  AN_ACTION_TYPE_START: 'AN_ACTION_TYPE_START',
  AN_ACTION_TYPE_COMPLETED: 'AN_ACTION_TYPE_COMPLETED',
  AN_ACTION_TYPE_FAILED: 'AN_ACTION_TYPE_FAILED',
}

*/

These constants can then be used as action types, which are especially useful for use with redux-token-api-middleware.
