Create Action Reducer

Abstractions suck so let's build an abstraction

Usage

import {createAction, createReducer} from '@beardedtim/create-action-reducer'

const ADD_USER = `ADD_USER`
const addUser = createAction(ADD_USER)

const userActions = {
  [ADD_USER]: (state,user) => [...state,user]
}

const userReducer = createReducer(userActions)

Now addUser is a normal redux action creator and userReducer is a normal redux reducer. addUser is waiting for payload and userReducer is waiting for (state,action)

createAction

This will create an action of {type,payload} using the following api:

const action = createAction(ACTION_TYPE)
action(payload) // ({type: ACTION_TYPE, payload: payload})

• This returns a function that is your 'action creator' and the returned function is your 'action'

createReducer

This will create a reducer with a default key that just returns the state. This needs your actions to be given as a dictionary/hash/object like so:

const actions = {
  [ADD_USER]: (state,payload) => [...state,payload]
}

and it can be used like so:

const actions = {
  ...
}

const reducer = createReducer(actions)

reducer(state,action) // new state
