components

import React from 'react'
import {
  useItems,
  useOptedItem,
  useLoading,
  useLoadItems,
  useSetItems,
} from '@ambroseus/dck-store'

export const Items: React.FC<{ itemType: string; optedItemId?: number }> = ({
  itemType,
  optedItemId,
}) => {
  const items: any[] = useItems(itemType)
  const loading = useLoading(itemType)
  const load = useLoadItems(itemType)
  const setItems = useSetItems(itemType)
  const optedItem = useOptedItem(itemType)

  return (
    <>
      <button onClick={() => load({ optedItemId })} disabled={loading}>
        {loading ? 'loading...' : 'load items'}
      </button>{' '}
      <button onClick={() => setItems([])}>clear items</button>
      <div />
      <pre>items: {JSON.stringify(items, null, 2)}</pre>
      <pre>opted item: {JSON.stringify(optedItem, null, 2)}</pre>
    </>
  )
}

import React from 'react'
import { Provider } from 'react-redux'
import { store } from './store'
import { Items } from './components/Items'
import { TestItem } from './items'

export const App: React.FC = () => (

sagas

import { all, takeLatest } from 'redux-saga/effects'
import { Process, isAction } from '@ambroseus/dck-store'
import { testLoadFetcher } from './fetchers'
import { TestItem } from './items'

export function* rootSaga() {

    yield proc.optItem(action.meta.options.optedItemId)
    yield proc.stop()
  } catch (e) {
    yield proc.fail(e)

}

store

import { configureStore } from '@reduxjs/toolkit'
import createSagaMiddleware from 'redux-saga'
import { dckReducer } from '@ambroseus/dck-store'
import { rootSaga } from './rootSaga'

const sagaMiddleware = createSagaMiddleware()

export const store = configureStore({
  reducer: { dck: dckReducer },
  middleware: [sagaMiddleware],
  preloadedState: {},
})

sagaMiddleware.run(rootSaga)
