pnpm add resso
# or
yarn add resso
# or
npm i resso
import resso from 'resso';
const store = resso({
count: 0,
text: 'hello',
inc() {
const { count } = store; // 须在顶层解构(若在方法中用到)
store.count = count + 1;
},
});
function App() {
const { count } = store; // 须在顶层解构(若在 UI 中用到)
return (
<>
{count}
<button onClick={() => (store.count += 1)}>+</button>
</>
);
}
* 顶部解构其实是调用 useState
(Hooks 规则,否则将有 React 报错)
更新单个
store.count = 60;
store('count', (c) => c + 1);
更新多个
store({
count: 60,
text: 'world',
});
store((s) => ({
count: s.count + 1,
text: s.text === 'hello' ? 'world' : 'hello',
}));
非 state 共享变量 (Refs)
事实上它与 resso 无关,只是 JavaScript。你可以这样做:
// store.js
export const refs = {
total: 0,
};
// App.js
import store, { refs } from './store';
function App() {
refs.total = 100;
return <div />;
}
* react<18
批量更新
resso.config({ batch: ReactDOM.unstable_batchedUpdates }); // 在项目入口
// 没有 text 更新,绝不 re-render
function Text() {
const { text } = store;
return <p>{text}</p>;
}
// 只在 count 更新时 re-render
function Count() {
const { count } = store;
return <p>{count}</p>;
}
// 没有 state 在 UI 中,绝不 re-render
function Control() {
return (
<>
<button onClick={store.inc}>+</button>
<button onClick={() => (store.count -= 1)}>-</button>
</>
);
}
