Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

pinia-state-sync-storage

v1.0.1

Published

Pinia cross-page state synchronization plugin

Readme

pinia-state-sync-storage

安装

npm i inia-state-sync-storage

用法

插件引入

import { PiniaNonreactiveState } from 'pinia-state-sync-storage';

pinia.use(
  PiniaStateSyncStorage({
    // 读取缓存的key
    key: 'storageKey',
  }),
)

pinia store配置

const useTestStore = defineStore({
  id: 'testStoreId',
  state: () => ({
    text: '123'
  }),
  stateSyncStorage: {
    key: 'storageKey',
    // key支持函数类型
    // key: (storeId) => `${storeId}_${queryId}`,
  },
})

key 对应 storage ID,需要和持久化插件的key保持一致。

清空事件监听:$unbindStorageEvents

页面卸载后,需要解绑 storage 事件监听:

onBeforeUnmount(() => {
  testStore.$unbindStorageEvents();
});

按需同步: useJsonPatch

const useStore = defineStore({
  id: 'testStoreId',
  state: () => ({
    text: '123'
  }),
  stateSyncStorage: {
    // 读取缓存的key
    key: 'storageKey',
    useJsonPatch: true,
  },
})

开启 useJsonPatch 后,插件会比对新旧缓存数据的差异,生成 json patch 数组,进而按需更新pinia状态。 useJsonPatch 关闭则使用 pinia.$patch 全量更新。

自定义反序列化函数: deserialize

const useStore = defineStore({
  id: 'testStoreId',
  state: () => ({
    text: '123'
  }),
  stateSyncStorage: {
    // 读取缓存的key
    key: 'storageKey',
    // 默认为`JSON.parse`
    deserialize: (data) => {
      return cusCudeserialize(data)''
    };
  },
})

该函数配置需要和持久化插件的反序列函数逻辑保持一致,如果持久化插件没有序列化函数的配置,则无需配置。 默认为JSON.parse
