ducktools - namespaced reducer package (duck) factories

reduce boilerplate and increase fun with redux

Why?

Boilerplate makes redux tedious. Most reducers are either just a value, async value or a list of values. These reusable, namespaced, state slice reducer packages help you save time

Usage:

createValueDuck

import { createValueDuck } from "@usagihana/ducktools"
/* Ducks bundle their namespaced reducer, action creators and action types
    createValueDuck returns:
    const duck = {
        namespace,
        reducer: namespace ? createReducerNamespace(valueReducer, namespace) : valueReducer,
        //types
        VALUE_CREATED, 
        VALUE_REMOVED,
        // action creators
        create, 
        remove,
    }
*/

// choose a namespace, onlyActions with correct namespaces will be send to these reducers
export const myValueDuck = createValueDuck('app_myValue');
export const reducer = myValueDuck.reducer





store.dispatch( myValueDuck.create('value') )
// store.dispatch({type:myValueDuck.VALUE_CREATE, namespace: 'myNamespace', payload:'value' })

store.dispatch( myValueDuck.remove() )
// store.dispatch({type:myValueDuck.VALUE_REMOVE, namespace: 'myNamespace' })

createAsyncDuck

import { createAsyncDuck } from "@usagihana/ducktools"
/*  createAsyncDuck returns:
    const duck = {
        namespace,
        reducer: namespace ? createReducerNamespace(asyncReducer, namespace) : asyncReducer,
        // types
        ASYNC_REQUESTED, 
        ASYNC_REJECTED,
        ASYNC_FULFILLED,
        // action creators
        request, 
        reject, 
        fulfill,
        // thunks
        asyncFetchData
    }
*/


export const myAsyncDuck = createAsyncDuck('app_myAsyncValue');
export const reducer = myAsyncDuck.reducer


store.dispatch( myAsyncDuck.request() )

setTimeout( () => {
  const data = 'value'
  store.dispatch( myAsyncDuck.fulfill(data) )
}, 1000)

// store.dispatch( myAsyncDuck.reject() )
// store.dispatch({type:myAsyncDuck.ASYNC_REJECTED, namespace: 'myNamespace'})

createListDuck

import { createListDuck } from "@usagihana/ducktools"
/*  createListDuck returns: 
    const duck = {
        namespace,
        reducer: namespace ? createReducerNamespace(listReducer, namespace) : listReducer,
        // type
        LIST_CREATED, 
        LIST_REMOVED,
        LIST_RESET,
        LIST_CREATEDMANY,
        LIST_SORT,
        // creators
        create, 
        remove,
        reset,
        createMany,
        sort
    }
*/


export const myListDuck = createListDuck('app_myList');
export const rootReducer = myListDuck.reducer


store.dispatch( myListDuck.create({ id: 'myId',  name: "bla" }) )
store.dispatch( myListDuck.create({ id: 'myId2', name: "bla" }) )
// store.dispatch({type:myListDuck.LIST_CREATE, namespace: 'myNamespace', payload:{ id: 'myId',  name: "bla" }})

/* Lists have a object with IDs as keys and a order array
store = {
    list: { 
        "myID": { id: "myID" },
        "myID2": { id: "myID2" }
    },
    listOrder: [
        "myID", 
        "myID2"
    ]
}
*/

Full Usage Example:

import { createValueDuck, createAsyncDuck, createListDuck } from "@usagihana/ducktools"


// choose a namespace, onlyActions with correct namespaces will be send to these reducers
//
const namespace = "myNamespace";

const myListDuck = createListDuck(namespace+'myList');
const myValueDuck = createValueDuck(namespace+'myValue');
const myAsyncDuck = createAsyncDuck(namespace+'myAsync');

const rootReducer = combineReducers({
    myList: myListDuck.reducer,
    myValue: myValueDuck.reducer,
    myAsync: myAsyncDuck.reducer
})


// create store 
const store = createStore(rootReducer, undefined, applyMiddleware(logger,thunk))


store.dispatch( myValueDuck.create('value') )


store.dispatch( myListDuck.create({ id: 'myId',  name: "bla" }) )
store.dispatch( myListDuck.create({ id: 'myId2', name: "bla" }) )


store.dispatch( myAsyncDuck.request() )

setTimeout( () => {
  const data = 'asyncvalue'
  store.dispatch( myAsyncDuck.fulfill(data) )
}, 1000)

/*
store = {
    myList: {
        list: { 
            "myID": { id: "myID" },
            "myID2": { id: "myID2" }
        },
        listOrder: [
            "myID", 
            "myID2"
        ]
    },
    myValue: 'value',
    myAsync: 'asyncvalue'
}
