vue中使用localstorage

1、store.js(读取写入到localstorage)

const STORAGE_KEY="todos-vuejs"
export default{
    fetch(){
        return JSON.parse(window.localStorage.getItem(
            STORAGE_KEY||"[]"))
    },
    save(items){
        window.localStorage.setItem(STORAGE_KEY,JSON.stringify(items))
    }
}

2、App.vue
