Store

const store = createStore({
    a: 1,
    b: 'test',
});
const computed1 = computed(() => {
    return store.a + store.b;
});
watch(store.a, (v, p) => {
    console.log(`a change: cur=${v}; prev=${p}`);
});
watch(computed1, (v, p) => {
    console.log(`computed1 change: cur=${v}; prev=${p}`);
});
watch(() => store.a + 1, (v, p) => {
    console.log(`store.a + 1 change: cur=${v}; prev=${p}`);
});
watch(join`hello ${store.b} ${raw(1)} ${store.a}`, (v, p) => {
    console.log(`join change: cur=${v}; prev=${p}`);
});
watchPure(() => store.a + 1, () => {
    console.log(`store.a + 1 pure change`);
});
watchImme(() => store.a + 1, (v, p) => {
    console.log(`store.a + 1 imme change: cur=${v}; prev=${p}`);
});

StorageStore

Binding State with localstorage

import { createStorage } from 'tc-store';
const store = createStorage({
    a: 1,
    b: 'test',
});

console.log(`store.a = ${store.a}`);

// this change will write into localstorage
// when you refresh the page, store.a will be 2
store.a = 2; 

// You can use all store methods

use $id

import { createStorage } from 'tc-store';
const store = createStorage({
    $id: 'my-store', // Custom you storage id
    a: 1,
    b: 'test',
});

DomStore

Binding State with HTMLElement

import { store, bind, watchImme} from 'tc-store';
const store = createStore({
    content: 'test',
});
const div = document.getElementById('div')!; // this is A Div
watchImme(store.content, (v) => {
    div.innerText = v;
});

const input = document.getElementById('input')!; // this is A Input Element(input, textarea, select, etc.)
bind(input, store.content); // This results in a two-way binding
