completeReducer

completeReducer - Completer

This completer can extend a reducer, helping to reduce its code size. It receives an object with different string arrays depending on how you want the resulting reducer to handle each action:

• primaryActions: Handles the _SUCEESS and _FAILURE actions with the onSuccess and onFailure effects.
• pollingActions: Handles the _RETRY, _CANCEL, _SUCEESS and _FAILURE actions with the onRetry, onCancel, onSuccess and onFailure effects.
• override: Overrides any effect this reducer has added. You can use a usual reducer here.

Example:

const actions = createTypes(completeTypes({
  primaryActions: ['PRIMARY_ACTION'],
  pollingActions: ['POLLING_ACTION'],
  ignoredActions: ['IGNORED_ACTION'],
  customCompleters: [{actions: ['CUSTOM_ACTION'], completer: action => `${action}_COMPLETED`}]
}), '@@NAMESPACE');
const reducerDescription = {
  primaryActions: [actions.PRIMARY_ACTION],
  pollingActions: [actions.POLLING_ACTION],
  override: {
    [actions.IGNORED_ACTION]: (state, action) => ({ ...state, someTarget: action.payload }),
    [actions.CUSTOM_ACTION_COMPLETED]: (state, action) => ({ ...state, someOtherTarget: action.payload }),
    [actions.PRIMARY_ACTION_FAILURE]: (state, action) => ({ ...state, someOtherTarget: action.payload }), // overrides the default onFailure() of PRIMARY_ACTION_FAILURE
  }
}

const completedReducer = completeReducer(reducerDescription);
/*
