Redux action creator

It is an unofficial utility function that is designed to reduce verbosity of redux action creators. It is so simple that can fit into a single line of code, but I think it's nice to have on NPM.

Installation

npm i --save action-creator-redux

import actionCreator from 'action-creator-redux';

Example

Here we have a common redux action that fetches users.

const types = {
  FETCH_ATTEMPT: 'FETCH_ATTEMPT',
  FETCH_SUCCESS: 'FETCH_SUCCESS',
  FETCH_FAILURE: 'FETCH_FAILURE',
};

const fetchAttempt = () => ({
  type: types.FETCH_ATTEMPT,
});

const fetchSuccess = users => ({
  type: types.FETCH_SUCCESS,
  payload: users,
});

const fetchFailure = err => ({
  type: types.FETCH_FAILURE,
  payload: err,
});

export const fetchUsers = () => async (dispatch) => {
  dispatch(fetchAttempt());

  try {
    ...
    dispatch(fetchSuccess(users));
  } catch (err) {
    dispatch(fetchFailure(err));
  }
};

Actions creators look pretty verbose, and you may have a lot of those in each file. Here's what we can do.

import actionCreator from 'action-creator-redux';

...

const fetchAttempt = actionCreator(types.FETCH_ATTEMPT);
const fetchSuccess = actionCreator(types.FETCH_SUCCESS);
const fetchFailure = actionCreator(types.FETCH_FAILURE);

...

The rest of the code remains the same. This approach implies that you adhere to unified structure of redux action. It means that all the data the action holds is put inside the payload property.

const fetchSuccess = actionCreator(types.FETCH_SUCCESS);
fetchSuccess('This is payload');
// { type: 'FETCH_SUCCESS', payload: 'This is payload' }

There is nothing more to it.
