vitruvius

Vitruvius extends redux's combineReducers to allow developers to include a buildInitialState method on their reducer. This allows for the passing of locals to build the initial state that wouldn't normally be available to a reducer when setting its initial state. For instance, one could pass some data from the request object.

Installation

$ npm install --save @crabas0npm2/autem-eveniet-maiores

Implementation

Below is an example of a reducer implementing a buildInitialState method and an example of vitruvius being implemented.

import { Map } from 'immutable';

export const SOME_ACTION = 'SOME_ACTION';

const buildInitialState = ({ data } = {}) => new Map({ foo: data || 'bar' });

export default function reducer(state = buildInitialState(), action) {
  switch (action.type) {
    case SOME_ACTION:
      return state.set('foo', action.data);
    default:
      return state;
  }
}

reducer.buildInitialState = buildInitialState;

TIP: To extend combineReducers from redux-immutable instead of redux import from @crabas0npm2/autem-eveniet-maiores/immutable.

import vitruvius from '@crabas0npm2/autem-eveniet-maiores';

const reducer = vitruvius({
  stuff: stuffReducer,
  things: thingsReducer,
  ...otherReducers,
});

const store = createStore(reducer, reducer.buildInitialState(locals), enhancer);
