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 🙏

使用

安装

1. cli 创建的 uniapp 项目

npm i pinia-plugin-unistorage -D
// main.js
import { createSSRApp } from "vue";
import * as Pinia from "pinia";
import { createUnistorage } from "pinia-plugin-unistorage";

export function createApp() {
  const app = createSSRApp(App);

  const store = Pinia.createPinia();

  // 关键代码 👇
  store.use(createUnistorage());

  app.use(store);

  return {
    app,
    Pinia, // 此处必须将 Pinia 返回
  };
}

2. hbuilderx 创建的 uniapp 项目

👉 直接插件市场安装 后引入注册

// main.js
import { createSSRApp } from "vue";
import * as Pinia from "pinia";
import { createUnistorage } from "./uni_modules/pinia-plugin-unistorage";

export function createApp() {
  const app = createSSRApp(App);

  const store = Pinia.createPinia();

  // 关键代码 👇
  store.use(createUnistorage());

  app.use(store);

  return {
    app,
    Pinia, // 此处必须将 Pinia 返回
  };
}

基础

import { defineStore } from "pinia";

export const useStore = defineStore("main", {
  state() {
    return {
      someState: "hello pinia",
    };
  },
  unistorage: true, // 开启后对 state 的数据读写都将持久化
});

或者 setup 语法也是支持的

import { defineStore } from "pinia";

export const useStore = defineStore(
  "main",
  () => {
    const someState = ref("hello pinia");
    return { someState };
  },
  {
    unistorage: true, // 开启后对 state 的数据读写都将持久化
  },
);

选项

钩子

import { defineStore } from "pinia";

export const useStore = defineStore("main", {
  state() {
    return {
      someState: "hello pinia",
    };
  },
  unistorage: {
    // 初始化恢复前触发
    beforeRestore(ctx) {},
    // 初始化恢复后触发
    afterRestore(ctx) {},
  },
});

序列化

大多数情况下你并不需要了解该选项

import { defineStore } from "pinia";

export const useStore = defineStore("main", {
  state() {
    return {
      someState: "hello pinia",
    };
  },
  unistorage: {
    serializer: {
      // 序列化,默认为 JSON.stringify
      serialize(v) {
        return JSON.stringify(v);
      },
      // 反序列化,默认为 JSON.parse
      deserialize(v) {
        return JSON.parse(v);
      },
    },
  },
});

其他

import { defineStore } from "pinia";

export const useStore = defineStore("main", {
  state() {
    return {
      foo: "foo",
      nested: {
        data: "nested pinia",
      },
      someState: "hello pinia",
    };
  },
  unistorage: {
    key: "foo", // 缓存的键,默认为该 store 的 id,这里是 main,
    paths: ["foo", "nested.data"], // 需要缓存的路径,这里设置 foo 和 nested 下的 data 会被缓存
  },
});
