Some functions which helps to reduce boilerplate in redux ducks files

ducks-helpers

Utils for ducks in redux to create action types and actions creators

###Installation

npm i --save ducks-helpers

###constants(namespace, actions) constants() - generates action types names If ~ sign presents at the beginning of the string then extra sufixes will be generated:

// available SUFFIXES

// 'LOADING'
// 'PENDING'
// 'SUCCESS'
// 'ERROR'
// 'FAILED'
// 'CANCELED'

How to use:

import {constants} from 'ducks-helpers'
export const TYPE = constants('module-name/namespace', [
    '~ASYNC_ACTION',
    'SYNC_ACTION'
])

Result:

// with ~
// TYPE.ASYNC_ACTION === 'module-name/namespace/ASYNC_ACTION'
// TYPE.ASYNC_ACTION_SUCCESS === 'module-name/namespace/ASYNC_ACTION_SUCCESS'
//...
// TYPE.ASYNC_ACTION_CANCELED === 'module-name/namespace/ASYNC_ACTION_CANCELED'

// without ~
// TYPE.SYNC_ACTION === 'module-name/namespace/SYNC_ACTION'

Using handleActions() from redux-actions

// reducer
export default handleActions({
    [TYPE.SYNC_ACTION]: (state, action) => state,
    [TYPE.ASYNC_ACTION]: (state, action) => state,
    [TYPE.ASYNC_ACTION_LOADING]: (state, action) => state,
    //... other suffixes also are available and can be used
    [TYPE.ASYNC_ACTION_SUCCESS]: (state, action) => state,
    [TYPE.ASYNC_ACTION_ERROR]: (state, action) => state,
}, {})

###actions(types)

types is an array of constants. In case of using ~ sign at the beginning of action name it will also create action creators with suffixes syncAction, asyncAction, asyncActionLoading, asyncActionPending, asyncActionCanceled, asyncActionError, asyncActionFailed using redux-actions:

import {actions} from 'ducks-helpers'
export const ACTION = actions(TYPE)

All action creators have been built now. You can use any action creators in your container.

// container.js
import { ACTION } from '../duck'
...
@connect(
    ...,
    {
        asyncAction: ACTION.asyncAction
    }

)
...

componentWillMount(){
    this.props.asyncAction()
}

...
