react-native-simple-local-storage

@react-native-community/async-storage 组件的同步写法

原理

一开始就将保存的数据全部导入内存中，初始化完毕后就可以直接在内存操作，速度更快

Install

$ yarn add react-native-simple-local-storage

Simple use

1 //在入口文件中;
2 import 'react-native-simple-local-storage';
3 function App(){
4   const [isReady, setReady] = useState(false);
5   useEffect(() => {
6     global.localStorage.isReady.then(() => setReady(true));
7    }, []);
8   if (!isReady) {
9     return null;
10   }
11   return (<View>
12            <Button onPress={() => global.localStorage.setItem('key', 'value')}>setItem</Button>
13            <Button onPress={() => console.log(localStorage.getItem('key'))}>getItem</Button>
14            <Button onPress={() => localStorage.removeItem('key')}>removeItem</Button>
15            <Button onPress={() => localStorage.clear()}>clear</Button>
16            <Button onPress={() => console.log(global.localStorage.length)}>length</Button>
17            <Button onPress={() => console.log(global.localStorage.byteSize)}>byteSize</Button>
18   </Layout>);
