Redux-kit

LIVE DEMO

Installation

yarn add @wellyes/redux-kit

Purpose

Library for reducing amount of redux code. Everything that you need is to call "builder" methods that will easly configure your app store.

What's Included

• actionCreatorFactory - simply implements typescript-fsa.

    import { actionCreatorFactory } from '@wellyes/redux-kit';
  
    const actionCreator = actionCreatorFactory('pokemons');

  returns builder which allows to create async and sync actions.

    const syncAction = actionCreator('sync');
    const asyncAction = actionCreator.async<
      object,
      PokemonResponse,
      ErrorResponse
    >('async');
  
    asyncAction.pending();
    asyncAction.done();
    asyncAction.failed();

• initWorker - wrapper around method that allows to create async action handlers. Accepts app axios instance and returns actionWorker factory, which allows to create action workers.

    import { actionCreatorFactory, initWorker, AsyncActionCreators } from '@wellyes/redux-kit';
  
    import axios from '@utils/axios';
  
    const payloadedWorker = initWorker(axios);
    const actionCreator = actionCreatorFactory('pokemons');
  
    export const pokemons: AsyncActionCreators<object, PokemonResponse, ErrorResponse> = actionCreator.async<
      object,
      PokemonResponse,
      ErrorResponse
    >('all');
  
    export const pokemonsWorker = (limit: number, offset: number) =>
  payloadedWorker(pokemons, `pokemon?limit=${limit}&offset=${offset}`, 'get');
      
    //You component code
    //Simply use dispath from react-redux package
    dispatch(pokemonsWorker(filters.limit, filters.offset)());
  
    //Example with body
    dispatch(pokemonsWorker(filters.limit, filters.offset)({
      example: 'of_body',
    }));
  
    //Example with callbacks
       dispatch(pokemonsWorker(filters.limit, filters.offset)({
      example: 'of_body',
    }, {
      cOnFail: (err) => console.log('Error', err),
      cOnSuccess: (payload) => console.log(payload),
      //formData flag is ussed to send body as multipart/form-data
      //Library will automatically convert u'r object to formdata.
      //default value is false
      formData: true
    }));

• eraseWorker - method that generates handler to clear any field in store.

• reducer - method that generates default async reducer with action types:

  • pending - request started
  • done - request ended without errors
  • failed - request ended with errors

  import { Action, reducer } from '@wellyes/redux-kit';

  import { pokemons } from './pokemons.actions';

  export const pokemonsReducer = (state: PokemonState = initialState, action: Action): PokemonState => {
  const states = {
    ...reducer(pokemons, state, action, { dataMask: 'pokemons', loadingMask: 'loading', errorMask: 'errors' }),
  };
  return states[action.type] ? states[action.type]() : state;
};

Basically ...reducer(ACTION_TYPE, STATE, CUR_ACTION, { SETTINGS }) generates object with keys ACTION_NAME_PENDING, ACTION_NAME_DONE, ACTION_NAME_FAILED. SETTINGS object contains of:

1. dataMask - mask for your response(asyncAction.done()), will be updated with async action payload if async action ends without errors.
2. loadingMask - loading mask will automatically set to true after you async action will be emitted asyncAction.pending() and false after it will ends with error or not.
3. errorMask - errorMask will be seted with error payload(asyncAction.failed(new Error())) in case of any errors.

• eraseReducer - generates reducer for erasing any fields in store.
• createStore - simply implements redux createStore method.
• combineReducers - simply implements redux combineReducers method.
