right value; when aggregating subduxes selectors Updux auto-wraps them to
|

access the right slice of the top object. ```
|
||||
|
||||
## Reactions
|
||||
|
||||
Reactions -- aka Redux's subscriptions -- can be added to a updux store via the initial config
|
||||
or the method `addSubscription`. The signature of a reaction is:
|
||||
|
||||
```
|
||||
(storeApi) => (state, previousState, unsubscribe) => {
|
||||
...
|
||||
}
|
||||
```
|
||||
|
||||
Subscriptions registered for an updux and its subduxes are automatically
|
||||
subscribed to the store when calling `createStore`.
|
||||
|
||||
The `state` passed to the subscriptions of the subduxes is the local state.
|
||||
|
||||
Also, all subscriptions are wrapped such that they are called only if the
|
||||
local `state` changed since their last invocation.
|
||||
|
||||
Example:
|
||||
|
||||
```
|
||||
const todos = new Updux({
|
||||
initial: [],
|
||||
actions: {
|
||||
setNbrTodos: null,
|
||||
}
|
||||
reactions: [
|
||||
({dispatch}) => todos => dispatch.setNbrTodos(todos.length);
|
||||
],
|
||||
});
|
||||
|
||||
const myDux = new Updux({
|
||||
initial: {
|
||||
nbr_todos: 0
|
||||
},
|
||||
subduxes: {
|
||||
todos,
|
||||
},
|
||||
mutations: {
|
||||
setNbrTodos: nbrTodos => u({ nbrTodos })
|

}
