When should you use action creator and when reducer?

Action creator

  • you need to have side effects
  • you need to read from store to decide what to do
  • you need to dispatch more than one action
  • action produced by action creator needs to contain all the data reducer can need to shape the components state

Reducer

  • should not have any side effects
  • should not read global application state
  • should not manipulate data structures passed with the action, it should only pick the right data and merge it into state
