Common Reducers

Because I got tired of re-writing these every reducer

Array Methods

Usage

import {add, updateByKey, removeByKey} from '@beardedtim/common-reducers'
const reducer = {
  [ADD_USER]: add,
  [UPDATE_USER]: updateByKey('_id'),
  [REMOVE_USER]: removeByKey('_id')
}

which is dependent on the action looking like this:

addUser(user) // {type: ADD_USER, payload: user}
updateUser({_id: _id, update}) // {type: UPDATE_USER, payload: {_id,update}}
removeUser(_id) // {type: REMOVE_USER, payload: _id}

If you want to remove more than one item at a time, you can use unique=false when creating removeByKey:

[REMOVE_MATCHING_NAME]: removeByKey('name',false)

this will now filter out all objects inside of state who have a property called name that is set to whatever is passed in by removeUser
