use-async-ops-redux

An use-async-ops middleware to add redux actions that mimic the previous project async-ops

Example

import { createStore } from 'redux'
import { prependMiddleware } from 'use-async-ops'
import { reduxMiddleware } from 'use-async-ops-redux'
 
const store = createStore(reducer)
prependMiddleware(reduxMiddleware(store.dispatch))

Action Types

The actionTypes object contains the Redux action type strings for Async-Ops actions. The action types are:

• actionTypes.OPERATION = 'ASYNC_OPERATION'
• actionTypes.COMPLETE = 'ASYNC_COMPLETE'
• actionTypes.FAILURE = 'ASYNC_FAILURE'

Optional Reducer and Selectors

use-async-ops-redux ships with a reducer and two selectors that can be used to keep track of the loading and errors states.

Reducer

A Redux reducer is included that can be optionally added to an app's reducer to keep the store updated with the status about the latest use-async-ops calls. It must be put under the key 'asyncops' which can be imported from the async-ops package as STORE_DOMAIN.

import { combineReducers } from 'redux'
import { reducer as asyncops } from 'async-ops'
 
const rootReducer = combineReducers({
  asyncops
})

Loading Selector

This selector function can be used to determine the loading state of an asynchronous operation.

import { selectors } from 'use-async-ops-redux'
 
const mapStateToProps = state => ({
  testOpIsLoading: selectors.loadingSelector('testOp')(state)
})

Error Selector

This selector function can be used to retrieve error data from an asynchronous operation.

import { selectors } from 'async-ops'
 
const mapStateToProps = state => ({
  testOpError: selectors.errorSelector('testOp')(state)
})
