Redux Enhancer

What is it?

Tired of always copy pasting a lot of redux boilerplate everytime you create a new store, or handle an async action?

• Automaticaly generate the state of your async actions!
• Automaticaly generate reset store

But in depth?

Enhance your redux modules:

• Automaticaly handling the start, loading, error or success, and reset Redux phases of your async calls
  • Four action types will be automaticaly created such as:

    {
      REQUEST: {
        SIGNUP: {
          START: `USER.REQUEST.SIGNUP.START`,
          SUCCESS: `USER.REQUEST.SIGNUP.SUCCESS`,
          FAILED: `USER.REQUEST.SIGNUP.FAILED`,
          RESET: `USER.REQUEST.SIGNUP.RESET`,
        },
      },
    }

  • Two states will be automaticaly added such as:

    {
      requests: {
        LOGIN: {
          loading: true,
          failed: false,
        },
      },
    }

  • Two selectors corresponding to the state will be automaticaly generated such as:

    {
      signupLoading: (state) => state.user.requests.LOGIN.loading,
      signupFailed: (state) => state.user.requests.LOGIN.failed,
    }

• Adding a RESET_STORE action to your different stores re-initializing your stores to their defaultState
  • An action type and action creator are generated:

    { RESET_STORE: 'RESET_STORE' }
    { resetStore: () => ({ type: 'RESET_STORE' }) }  

  • Your enhanced reducer will handle automaticaly your stores reset when dispatching the action

How to use? Full example here

1. In your redux module file(s) import the necessary enhancers:

import { enhanceActionTypes, enhanceActionCreators,
  enhanceDefaultState, enhanceReducer, enhanceSelectors } from 'redux-enhancer';
...

1. Create two variables, a string for the name of your store, an array of string in caps for your async calls:

...
const storeName = 'USER';
const asyncActionsNames = ['SIGNUP'];
...

1. Enhance your action types by passing the storeName and asyncActionsNames:

...
const actionTypes = {
  ...enhanceActionTypes(storeName, asyncActionsNames),
  LOGOUT: 'LOGOUT',
};
...

1. Enhance your action creators by passing the storeName, apiActionsNames and actionTypes:

...
const actionCreators = {
  ...enhanceActionCreators(storeName, asyncActionsNames, actionTypes),
  requestSignupStart: signupInfo => ({
    type: actionTypes.REQUEST.SIGNUP.START,
    payload: signupInfo,
  }),
};
...

1. Enhance your default state by passing the asyncActionsNames:

...
const defaultState = {
  ...enhanceDefaultState(asyncActionsNames),
};
...

1. Create your normal reducer and enhance it afterwards by passing the storeName:

...
const basicReducer = (state, action) => {
  switch (action.type) {
    case actionTypes.REQUEST.SIGNUP.SUCCESS:
      return {
        ...state,
        token: action.payload.token,
      };
    default:
      return state;
  }
};
 
const reducer = (state = defaultState, action) =>
  enhanceReducer(storeName, state, action, defaultState, basicReducer);
...

1. Enhance your selectors by passing the storeName and asyncActionsNames:

...
const selectors = {
  ...enhanceSelectors(storeName, asyncActionsNames),
  token: (state) => state.user.token,
};
...

1. Use your newly generated actions and state inside your app:

// In a container?
const mapStateToProps = (state) => ({
  signupLoading: selectors.signupLoading(state),
  signupFailed: selectors.signupFailed(state),
});
const mapDispatchToProps = {
  startSignup: actionCreators.startSignup,
  resetSignup: actionCreators.resetSignup,
};
 
// With a saga for instance
function* signupSaga(action) {
  try {
    const { email, password, nickname } = action.payload;
    const { token } = yield call(api.signup, email, password, nickname);
    yield put({ type: actionTypes.REQUEST.SIGNUP.SUCCESS, payload: { token } });
  } catch (err) {
    yield put({ type: actionTypes.REQUEST.SIGNUP.FAILED, payload: { err } });
  }
}

Todo

1. Rename the package to make it more explicit and less generic
2. Check the licence
3. Find a way to flow type the automaticaly created actions and selectors
