    vitruvius

    npm version Build Status

    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 @americanexpress/vitruvius
    

    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 @americanexpress/vitruvius/immutable.

    import vitruvius from '@americanexpress/vitruvius';
    
    const reducer = vitruvius({
      stuff: stuffReducer,
      things: thingsReducer,
      ...otherReducers,
    });
    
    const store = createStore(reducer, reducer.buildInitialState(locals), enhancer);
