Reactive tools for React.js

• createState - create state reactive variable that can be get and set from everywhere and subscribed to changes in react components
• createStateMap - create state reactive variable that can be get and set from everywhere and subscribed to changes in react components
• createAction - create action that can be dispatched from everywhere and subscribed in react components
• createCustomPubSub - create a custom PubSub that can publish from everywhere and subscribe by channel in react components
• createFixedPubSub - create a preconfigured PubSub that can publish from everywhere and subscribe by channel in react components

Examples:

Create a new reactive state of generic type:

const exampleState = createState<number>(0);

Update the state:

exampleState.set(10);

Get the state from everywhere:

const example = exampleState.get();

Subscribe for state updates in react components:

const example = exampleState.subscribe();

Get the state from everywhere ( with prev value ):

const { prev, current } = exampleState.get(true);

Subscribe for state updates in react components ( with prev value ):

const { prev, current } = exampleState.subscribe(true);

Reset the state from everywhere and return it to initial value:

exampleState.reset();

Create a new reactive state map of generic type:

const exampleStateMap = createStateMap<number>(0);

Update the state by some key (string | number):

exampleStateMap.set('key', 10)

Get the state by key from everywhere:

const example = exampleStateMap.get('key')

Subscribe for state updates by key in react components:

const example = exampleStateMap.subscribe('key');

Get the state of whole map from everywhere:

const example = exampleStateMap.getMap()

Subscribe for state updates of whole map in react components:

const example = exampleStateMap.subscribeMap();

Reset state by key and return it to initial value:

const example = exampleStateMap.reset('key');

Reset state for whole map and return it to initial value:

const example = exampleStateMap.resetMap();

Create a new reactive action of generic type (can be and void):

const exampleAction = createAction<string>();

Dispatch action from everywhere:

exampleAction.dispatch("Hi")

Subscribe for action in react components

exampleAction.subscribe(useCallback((value) => {
    console.log(`Action with value: ${value}`);
}, []))

Create a new PubSub:

const customPubSub = createCustomPubSub('customPubSub');

Publish to channel from everywhere:

customPubSub.publish<string>('someChannelName', 'World!')

Subscribe by channel in react components

customPubSub.subscribe<string>("someChannelName", useCallback((value) => {
    console.log(`Hello ${value}`);
}, []))

Also supports void pub/sub for action trigger

Create a new PubSub with predefined channel config:

type PubSubConfig = {
    channel: "channel1",
    dataType: string,
} | {
    channel: "channel2",
    dataType: number,
}

const fixedPubSub = createFixedPubSub<PubSubConfig>('fixedPubSub')

Publish to channel from everywhere:

fixedPubSub.publish('channel1', 'World!')

Subscribe by channel in react components

fixedPubSub.subscribe("channel1", useCallback((value) => {
    console.log(`Hello ${value}`);
}, []))

Also supports void pub/sub for action trigger
