Fetch Data

Declarative data fetching for Redux and React.

Install

npm

npm install --save-dev @unfold/fetch-data

yarn

yarn add --dev @unfold/fetch-data

Usage

1. Add middleware to Redux store

import { createFetchMiddleware } from '@unfold/fetch-data'

const store = createStore(reducers, initialState, applyMiddleware(thunk, createFetchMiddleware()))

2. Create reducers for requests and entities

import { createRequestsReducer, createEntityReducer } from '@unfold/fetch-data'
import { combineReducers } from 'redux'

const reducers = combineReducers({
  requests: createRequestsReducer(),
  posts: createEntityReducer('LIST_POSTS')
})

3. Add declarative data requirements to your components

import fetchData, { createFetchAction } from '@unfold/fetch-data'

const listPosts = () => createFetchAction({
  url: 'http://api.io/posts'
})

const ProfileContainer = fetchData({
  mapPropsToAction: () => listPosts()
}, {
  mapStateToProps: ({ posts }) => posts
})
