🗃 Small Store

A small, immutable, reactive and framework agnostic state store under 2KB
powered by rxjs and immer with native typescript support. To be used with
vanilla, react, preact, angular, vue or whatever you like.

Quick Start

import { Actions, Store } from 'small-store';
// state declaration
interface CounterState {
  count: number;
}
// actions
enum CounterAction {
  Increment = 'increment',
  Decrement = 'decrement'
}
// action functions
const counterActions: Actions<CounterState, CounterAction> = {
  [CounterAction.Increment]: () => state => {
    state.count++;
    return state;
  },
  [CounterAction.Decrement]: () => state => {
    state.count--;
    return state;
  }
};
// the initial state
const initialCounterState: CounterState = {
  count: 0
};
// creating the store
const counterStore = new Store<CounterState, CounterAction>(
  initialCounterState,
  counterActions
);
// subscribing to the store's state
counterStore.state$.subscribe(state => console.log(state));
// dispatching actions
counterStore.dispatch(CounterAction.Increment);
counterStore.dispatch(CounterAction.Increment);
counterStore.dispatch(CounterAction.Decrement);
