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 🙏

vue-cacheable-dictionary

v1.0.0

Published

A cacheable dictionary library for Vue.

Readme

vue-cacheable-dictionary

English README

一个面向 Vue 3 的可缓存字典加载器:维护响应式字典仓库、去重并发请求,并支持按 key 随用随取。

安装

pnpm add vue-cacheable-dictionary
# 或
npm i vue-cacheable-dictionary

使用

通常在一个 composable/模块中创建单例,提供 load 方法,然后按需查询字典。

import { createDictionaryInstance, type DictItem } from 'vue-cacheable-dictionary'

interface MyDictItem extends DictItem {
  color?: string
}

const dict = createDictionaryInstance<MyDictItem>({
  load: async (dicts) => {
    const res = await fetch('/dict', {
      method: 'POST',
      headers: { 'Content-Type': 'application/json' },
      body: JSON.stringify(dicts),
    })
    return res.json() as Promise<Record<string, MyDictItem[]>>
  },
})

export const useDict = dict.getDictData

组件内使用:

import { computed } from 'vue'
import { useDict } from './useDict'

const store = useDict(['type', 'status'])

const statusLabel = computed(() => store.get('status')?.label(1) ?? '')

你会得到什么

  • createDictionaryInstance(...):创建实例,负责缓存与请求去重。
  • DictArray:类数组封装,提供 pick / omit / label / item 等便捷方法。
  • DictItem / DictKey:字典数据类型定义。

说明

  • 只有字符串类型的 key 会传给 load(...);非字符串 key(例如 Symbol)会被忽略,不会触发远程请求。
  • 字典仓库底层是 Map 且具备响应式能力,可直接用于模板与 computed。

开发

pnpm install
pnpm play
pnpm test
pnpm build
pnpm typecheck
