onFailure

onFailure - Effect

This effect is used when describing the FAILURE 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 with your action.payload by default.
• Put ${action.target}IsRetrying in false if action.isPolling is truthy
• Put ${action.target}CountRetry in 0 if action.isPolling is truthy

Example:

const reducerDescription = {
  [actions.ON_FETCH_FAILURE]: onFailure()
}

Custom selectors

onFailure effect receives an optional parameter:

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