I want to dispatch one of the action in the array based on a I am trying to dispatch different action based on type splitting up in several effects. My current effect code is like that here is my effect code in which currently i am dispatching single action from effect. I I learnt that we can dispatch multiple actions from an effect in NgRx by returning an Observable array having multiple actions. I know i am doing something wrong or thinking in a wrong way, so I am sharing my concerns. If the distinction of an action isn't clearly communicated this leads to different opinions and thus also different implementations, such as the Dispatching multiple actions at once is considered an anti-pattern.
