ducks-request v0.0.3

Ducks Request

Request reducer and actions creator

Installation

yarn add ducks-request

Usage

1. Import the creator function and execute it to create new named request

// requests.js

import createRequest from 'ducks-request'

export const fooRequest = createRequest('foo')
export const barRequest = createRequest('bar', true)  // second argument `true` will preserve the request result in the reducer

createRequest returns a ducks module with action creators and reducer:

{
  started: ActionCreator<P>
  done: ActionCreator<Success<R, S>>
  failed: ActionCreator<Failure<R, E>>
  reset: ActionCreator<P>
  reducer: Reducer<Request<R, E>>
}

2. Combine the reducers:

// reducers.js

import { fooRequest, barRequest } from './requests'
import { combineReducers } from 'redux'

export default combineReducers({
  fooRequest.reducer,
  barRequest.reducer
})

3. Use them in components

// component.jsx

import * as React from 'react'
import { connect } from 'react-redux'
import { barRequest } from './requests'

const MyComponent = props => {
  const { result, pending } = props.barRequest
  return (
    <div>
      {pending && (
        <p>Loading...</p>
      )}

      {result && (
        <p>{result}</p>
      )}
    </div>
  )
}

export default connect(
  state => ({
    barRequest: state.barRequest
  }),
  {
    barRequestStarted: barRequest.started
  }
)
