redux-modular-models

Manage models state for CRUD with ease.

• Installation
• Usage Example
  • Create model reducer and update state with actions
  • Selectors

Installation

yarn add redux-modular-models

Usage Example

The store should know how to handle actions. To enable this, we need to create the modelReducer to your store. It serves for all of your models, so you only have to pass it once.

Create model reducer and update state with actions

import { createStore, combineReducers } from 'redux';
import { schema } from 'normalizr';

import {
  createReducer,
  arrayRemoveAll,
  arrayConcat,
  entityMerge,

  const itemSchema = new schema.Entity('item', { user: userSchema }, options);
  const collectionSchema = new schema.Entity(
    'collection',
    { user: userSchema },
    options,
  );

  const rootReducer = combineReducers({
