Concurrent actions in redux
So I have 2 actions:
- Ship a Arrived
- Ship b Arrived
Both these actions can happen at the same time, of course, one will go through the reducer first and the other one second.
But, on each ship arrived we need to remove some money.
The problem is the following:
- I have only $1 in the account
- First ship arrives and updates the ship and account reducer
- Second ship arrives and updates the ship, but the account has no money. In this case I'd like to don't process the ship arrival (is a simplified version of the bigger picture)
(the check for the money is done at the action creator level. When the 2nd ship is created will still read the previous money, which is not correct.)
Now the question is how to do it?
Option A:
- Have a root reducer which listens on this action
- Will delegate the ship update to the ship reducers only if there are money in the account first.
But I don't really like it that much, any other options?
