redux-p redux middleware accepts action type in action.type and Promise in action.payload.

• Dispatches action with action.type + '_PENDING' type as Promise is received
• ... action.type + '_FULFILLED' type as Promise is resolved (result set to action.payload)
• ... action.type + '_REJECTED' type as Promise is rejected (error set to action.payload)

redux-p was made to replace redux-promise-middleware basic interface for react-native, since redux-promise-middleware throws an error on Promise reject (this complicates development and requires special handling for react-native code).

Install

npm install redux-p --save

Use

import { applyMiddleware, createStore } from 'redux'
import reduxPromise from 'redux-p'

const middleware = applyMiddleware(reduxPromise)

const store = createStore(
	(state={}, action) => {
		switch (action.type) {
			case 'GITHUB_STATUS_PENDING':
				console.log('Pending')
				return { pending: true }

			case 'GITHUB_STATUS_FULFILLED':
				console.log('GitHub Status:', action.payload)
				return { pending: false, error: false, payload: action.payload }

			case 'GITHUB_STATUS_REJECTED':
				console.error('Error:', action.payload)
				return { pending: false, error: true, payload: action.payload }

			default:
				return state
		}
	},
	middleware
)

store.dispatch({
	type: 'GITHUB_STATUS',
	payload: fetch('https://github.com/status')
})
