uniapp pinia实现数据持久化插件

uniapp时间数据持久化兼容多端，话不多说直接上代码。

第一步新建一个插件index.js，内容如下：

import { onLoad } from "@dcloudio/uni-app";

const KEYPREFIX = 'PINIA:STATE:'

export function storeStorage({store}){
	const KEY = KEYPREFIX + store.$id;
	onLoad(()=>{
		const item = uni.getStorageSync(KEY)
		if(!item) return;
		try{
			const originState = JSON.parse(item);
			store.$patch(originState)
		}catch(e){
			console.log('e',e);
			console.log('存储格式无效');
		}
	})
	
	const saveState = () => {
	    try {
	      uni.setStorageSync(KEY, JSON.stringify(store.$state))
	    } catch (e) {
	      console.error('保存状态失败', e);
	    }
	}
	
	let saveTimer = null;
	store.$subscribe((mutation, state) => {
		if (saveTimer) clearTimeout(saveTimer);
		saveTimer = setTimeout(saveState, 1000);
	})
}

第二步，在main.js中引入并使用

//路径是自己刚才所建js的文件路径
import {storeStorage} from '../plugins/storeStorage.js'
import * as Pinia from 'pinia';


import { createSSRApp } from 'vue'
export function createApp() {
  const app = createSSRApp(App)
  const pinia = Pinia.createPinia()
  pinia.use(storeStorage)
  app.use(pinia);
  return {
    app,
	Pinia
  }
}
