Side Effects in Action Creators

One of the most common approaches seen in online Redux tutorials is to handle side effects inside action creators using redux-thunk. The solution appears to be quite straightforward:

//Handling side effects with redux-thunk
const addItemToCart = item => (dispatch, getState) => {
  dispatch(updateCart(item));

  if (getState().cart.items.length > 10) {
    dispatch(applyDiscount(20));
  }

  dispatch(showNotification(`${item.name} has been added to cart!`));
}
