Random Number Generator

The RNG task handler allows generating random numbers outside of the reducer, so as not to make the reducer impure.

Task: Default

This task causes a random number to be generated and to be dispatched back to as payload of the prescribe action.

{
  type: 'rng',
  actions: {
    result: string // action type to dispatch when the number has been generated
  }
}

Actions

Event Type	Meta	Payload
result	none	number

    case 'RANDOM_NUMBER':
      return addTask(state, {
        type: 'rng',
        actions: {
          result: 'RANDOM_NUMBER_RESULT'
        }
      })

    case 'RANDOM_NUMBER_RESULT':
      return {
        ...state,
        randomNumber: action.payload
      }

    default:
      return state
