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)
})
