List Reducer Actions

• addItemAction - add item to list (end).
• addItemsAction - add items to list (end).
• insertItemAction - insert item into list at given index.
• removeItemAction - remove item from list at given index.
• removeItemByKeyAction - remove item from list by "key".
• updateItemAction - update item at given index.
• updateItemByKeyAction - update item by "key".
• updateItemsByKeyAction - update items by "key".
• updateValueAllItemsAction - update key/value pair(s) on all items.
• setListAction - completely use new state and override current.

addItemAction({ 
    item: { id: 1 },
})

addItemsAction({ 
    items: [ { id: 1 } ],
})

insertItemAction({ 
    item: { id: 1 }, 
    index: 3,
})

removeItemAction({
    index: 3,
})

removeItemByKeyAction({ 
    item: { id: 1 },
    key: "id",
})

updateItemAction({ 
    item: { 
        id: 1, 
        newKey: "newValue" 
    }, 
    index: 3,
})

updateItemByKeyAction({ 
    item: {
        id: 1, 
        foo: "bar" 
    },
    key: "id",
})

updateItemsByKeyAction({ 
    items: [ 
        {
            id: 1, 
            foo: "bar" 
        }, 
        {
            id: 2, 
            cool: "beans" 
        },
    ],
    key: "id",
})

updateValueAllItemsAction({ 
    keyValuePairs: {
        foo: bar,
        updated: true,
        collapsed: true,
    }
})

setListAction({ 
    payload: [],
})

Object Reducer Actions

• updateObjectAction - update object key/value, can pass multiple key/value pair.
• setObjectAction - completely use new state and override current.

updateObjectAction({ 
    payload: { loading: true }, 
})

resetObjectAction()

setObjectAction({ 
    payload: {},
})

String Reducer Actions

• setStringAction - completely use new state and override current.

setStringAction({ 
    string: "foo bar",
})

Boolean Reducer Actions

• setBooleanAction - completely use new state and override current.
• toggleBooleanAction - toggle the state of the boolean.

setBooleanAction({ 
    payload: true,
})

toggleBooleanAction()

Number Reducer Actions

• incrementNumberAction - increment number.
• decrementNumberAction - decrement number.
• setNumberAction - set number.

incrementNumberAction()

decrementNumberAction()

setNumberAction({ 
    number: 100,
})

Each reducer, consider it like a micro service, it does one thing and one thing well.
