Quick Start

tsx

import { defineStore, useStore } from 'valtio-define'

const store = defineStore({
  state: () => ({ count: 0 }),
  actions: {
    increment() { this.count++ },
  },
  getters: {
    doubled() { return this.count * 2 },
  },
})

function Counter() {
  const state = useStore(store)
  return (
    <div>
      <div>Count: {state.count}</div>
      <div>Doubled: {state.doubled}</div>
      <button onClick={store.increment}>Increment</button>
    </div>
  )
}
