javascript state management that is:
- minimal ~ there is only 3 properties
- tiny ~ only 1.8kb
- reactive ~ fully reactive to state changes with help of 'subscribe' method
- performant ~ you can subscribe to a part of the state and intercept its changes
class SimpleState<T extends object>{
get data(): T;
unsubscribe(callbackFn: Subscriber): void;
subscribe<G = T>(selectorString: string & NestedKeyOf<T>, callbackFn: Subscriber<G>): Subscriber<G>;
}import { SimpleState } from "@arashes/simplestate";
const store = new SimpleState({
personalInfo: {
name: "",
},
});
input.addEventListener("input", (evt) => {
const name = (evt.target as HTMLInputElement).value as string;
store.data.personalInfo.name = name;
});
store.subscribe<string>("personalInfo.name", (name) => {
inputShow.innerHTML = name;
// runs on every input changes
});
