Helper functions to create reducers and actions, which can be re-used multiple times within a state. The action-types will be prefixed by slice key (sk), where the slices has to be stored in.

Prerequisite

Knowledge of redux-actions and -reducers

Example

state

{
	a:{},
	table:{
		page:0
	},
	anOtherTable:{
		page:0
	}
	b:{
		m:{
			page:0
		}
	}
}

reducer

import {createReducerSk, combineReducerSk} from '@pubcore/redux-slicify'

//example slice reducer
const page = (sk, initState=0) => createReducerSk(
	initState,
	{
		NEXT: (s, action) => s + action.step,
		BACK: (s, action) => s - action.step
	},
	sk
)

//slicified combined reducer, beware returning array
const table = [sk => combineReducerSk(
	{
		page
	},
	sk
)]

//slicified root reducer
export default combineReducerSk({
	a: s => s||{},     //trivial reducer
	table,
	anOtherTable: table,
	b:{
		m: table //table some where in state
	}
})

action

import slicify from '@pubcore/redux-slicify'


const next = step => ({type:'NEXT', step})
const back = step => ({type:'BACK', step})

//let there be the redux "dispatch" function

//this will change to next page of table in state.b.m
dispatch( slicify('b.m', next(1)) )

//and this will change to previous page of anOtherTable:
dispatch( slicify('anOtherTable', back(1)) )
