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 🙏

特点

  • pinia 的持久化
  • ✅ 各个模块支持自定义持久化配置
  • ✅ 支持indexedDB、storage进行存储,解决容量大小问题
  • ✅ 支持通过配置前缀、后缀,防止子项目之间持久化数据互相污染

安装

// npm
npm i pinia-plugin-persistedstore
// yarn
yarn add pinia-plugin-persistedstore
// pnpm
pnpm i pinia-plugin-persistedstore

使用

初始化

// 直接配置插件
import { createPinia } from 'pinia'
import piniaPluginPersistedStore from 'pinia-plugin-persistedstore'

const pinia = createPinia()
pinia.use(piniaPluginPersistedstate)

如果你不想要同域名下子项目持久化数据之间互相污染,可以配置前缀或后缀

// 为缓存添加前缀后缀
import { createPlugin } from 'pinia-plugin-persistedstore';

const store = createPinia();

const store = createPinia();

store.use(
  createPlugin({
    prefix: 'sunshine_prefix',
    suffix: 'sunshine_suffix',
  }),
);

模块配置

模块想要启用持久化,可以配置 persist 参数,它的类型是 TPersist

export interface IBasePersist {
  // 持久化存储的key(可选)
  key?: string;
  // 需要持久化的数据的路径(可选)
  paths?: string[];
  // 还原前执行函数(可选)
  beforeRestore?: (context: PiniaPluginContext) => void;
  // 还原后执行函数(可选)
  afterRestore?: (context: PiniaPluginContext) => void;
  // 还原失败打印报错(可选)
  debug?: boolean;
}

export interface IPersist extends IBasePersist {
  // storage类型,有localStorage、sessionStroage(可选)
  storage?: Storage;
  // 使用 indexedDB 或 storage(可选)
  type?: 'storage' | 'db';
}

// persist 的类型
export type TPersist = boolean | IPersist;

当你要启用持久化时,可以这么做

export const useUserStore = defineStore({
  id: 'app-user',
  persist: true, // 开启持久化
  state: (): UserState => ({
    name: 'sunshine'
  })
});

当你设置 persist = true 时,此模块开启了持久化功能,相当于传入了

  persist: {
    storage: localStorage,
    type: 'storage',
    key: $store.id, // 此模块的默认id
    paths: null,
    beforeRestore: null,
    afterRestore: null,
    debug: false,
  }

当然你也可以自己去进行配置,比如以下例子

export const useUserStore = defineStore({
  id: 'app-user',
  persist: {
    type: 'db',
    key: 'user_key',
    paths: ['userInfo', 'token'],
    beforeRestore: () => {
      console.log('beforeRestore');
    },
    afterRestore: () => {
      console.log('afterRestore');
    },
    debug: true,
  },
  state: (): UserState => ({
    userInfo: null,
    token: undefined,
    roleList: [],
  }),
});
