onSuccess

onSuccess - Effect

This effect is used when describing the SUCCESS case of the SUCCESS-FAILURE pattern.

This effect is a multi-target effect - It modifies more than one target at the same time.

It will:

• Put ${action.target}Loading in false
• Put ${action.target}Error in null
• Fill ${action.target} with your action.payload by default, or use a selector provided
• Put ${action.target}IsRetrying in false if action.isPolling is truthy
• Put ${action.target}CountRetry in 0 if action.isPolling is truthy

Example:

const selector =
  (action, state) => action.payload || state[action.target];  

const reducerDescription = {  
  'SUCCESS': onSuccess(),  
  'SUCCESS_CUSTOM': onSuccess(selector)  
};  

Custom selectors

onSuccess effect receives an optional parameter:

• selector: This function describes how we read the data from the action.
  (action, state) => any
  By default, is:
  action => action.payload
